Johnson <stevenj@fftw.org> 182 183 * acx_pthread.m4: not sure if -mt uses -lpthread... 184 185 * acx_pthread.m4: added -mt flag 186 1872000-12-09 fftw <fftw@fftw.org> 188 189 * acx_pthread.m4: fixed position of AC_REQUIRE 190 191 * FAQ/fftw-faq.bfnn: addressed finite-precision floating-point in 192 FAQ 193 1942000-10-22 fftw <fftw@fftw.org> 195 196 * acx_pthread.m4: fixed comment 197 198 * gensrc/genfft.ml, gensrc/symmetry.ml: whoops, undo accidental 199 commit 200 201 * acx_pthread.m4, gensrc/genfft.ml, gensrc/symmetry.ml: many 202 changes 203 2042000-10-16 fftw <fftw@fftw.org> 205 206 * doc/fftw.texi: point rfftw users to fftw for prime sizes 207 2082000-10-04 fftw <fftw@fftw.org> 209 210 * acinclude.m4: newer xlc versions reportedly accept -qarch=auto 211 to automatically tune for the native host. 212 2132000-07-03 fftw <fftw@fftw.org> 214 215 * acinclude.m4: Punt on guessing -qarch/-qtune flags for AIX, 216 since there seems to be no good way to guess the CPU. 217 2182000-06-26 Matteo Frigo <athena@fftw.org> 219 220 * fftw/fftwnd.c: Unrolled loop to expose more parallelism. 221 2222000-06-07 fftw <fftw@fftw.org> 223 224 * configure.in: Added "mpcc" MPI compiler for IBM SP3. thanks to 225 Ferenc Molnar for the information. 226 2272000-06-03 Matteo Frigo <athena@fftw.org> 228 229 * gensrc/complex.ml, gensrc/complex.mli, gensrc/genfft.ml, 230 gensrc/symmetry.ml, gensrc/variable.ml: Implemented mp3mdct 231 generation mode for generating the MDCT used in mp3. 232 2332000-06-02 Matteo Frigo <athena@fftw.org> 234 235 * cilk/executor_cilk.cilk, cilk/fftw_cilk.cilkh, 236 cilk/fftwnd_cilk.cilk, cilk/Makefile, cilk/test_cilk.cilk, 237 cilk/time_cilk.cilk, fftw/malloc.c, fftw/planner.c, fftw/putils.c, 238 fftw/rader.c, fftw/twiddle.c: Adapted (simplified) to the 239 forthcoming Cilk-5.3 240 241 * gensrc/exprdag.ml: Iterate optimization until convergence. 242 Saves two fops in fhb_9.c 243 2442000-05-29 fftw <fftw@fftw.org> 245 246 * acx_pthread.m4: The autoconf folks like the macro name to be 247 quoted in AC_DEFUN. 248 2492000-05-20 fftw <fftw@fftw.org> 250 251 * fftw/fftw.h.in: If the user includes <complex.h> before 252 <fftw.h>, then use the new C99 complex type for fftw_complex. 253 This way, all the arithmetic operators, etcetera, are available to 254 the user. The C99 complex type should be binary-compatible with 255 FFTW's struct-based type. 256 257 * gensrc/ast.ml: deleted unused file 258 2592000-05-19 Steven G. Johnson <stevenj@fftw.org> 260 261 * acx_pthread.m4: synchronized with macro archive, and added in 262 Sequent -Kthread support. 263 2642000-04-05 Steven G. Johnson <stevenj@fftw.org> 265 266 * doc/fftw.texi: slight change for clarity 267 2682000-03-31 Steven G.

Thanks to Jonathan Wilkins for his time and the use of 292 his machine. 293 2942000-03-21 fftw <fftw@fftw.org> 295 296 * acx_pthread.m4: fixed AC_DEFINE for HAVE_PTHREAD 297 298 * acx_pthread.m4: added acknowledgments 299 300 * acx_pthread.m4: include description strings for AC_DEFINEs so 301 that autoheader will work 302 303 * acx_pthread.m4: check for pthread.h before checking for threads 304 libraries 305 306 * acx_pthread.m4: don't check for cc_r if threads weren't found 307 308 * acx_pthread.m4: check for -kthread, then -lpthread, then 309 -pthread 310 311 * threads/fftw_threads_test.c: added missing newline to error 312 message 313 314 * doc/fftw.texi: documented --with-openmp and --with-sgimp 315 316 * threads/fftw_threads.c: bug fix in compiler thread directive 317 loop 318 3192000-03-20 fftw <fftw@fftw.org> 320 321 * configure.in, fftw/config.h.in, threads/fftw_threads.c, 322 threads/fftw_threads-int.h: added experimental support for openmp 323 and sgi mp compiler directives for threads code 324 325 * Makefile.am: make sure acx_pthread.m4 is included in the dist 326 327 * acx_pthread.m4: minor rewording in comment 328 329 * acx_pthread.m4, configure.in, fftw/config.h.in, 330 threads/fftw_threads.c: Separated POSIX threads library checks 331 into a separate macro (ACX_PTHREAD) for submission to the autoconf 332 macro repository (replacing an earlier macro there by Alejandro 333 Cuervo). Also, added checks for -pthread compiler flag required 334 on FreeBSD (thanks to Jonathan Wilkins for the use of his machine 335 for testing). 336 3372000-03-02 Steven G. Johnson <stevenj@fftw.org> 338 339 * ChangeLog: fixed email addresses 340 341 * ChangeLog: updated 342 343 * mpi/sched.c, mpi/test_transpose_mpi.c, mpi/transpose_mpi.c, 344 rfftw/rexec2.c, rfftw/rexec.c, rfftw/rfftwf77.c, rfftw/rfftw.h, 345 rfftw/rfftwnd.c, rfftw/rgeneric.c, rfftw/rplanner.c, 346 tests/fftw_test.c, tests/rfftw_test.c, tests/test_main.c, 347 threads/executor_threads.c, threads/fftw_f77_threads.c, 348 threads/fftwnd_threads.c, threads/fftw_threads.c, 349 threads/fftw_threads.h, threads/fftw_threads-int.h, 350 threads/fftw_threads_test.c, threads/rexec2_threads.c, 351 threads/rexec_threads.c, threads/rfftw_f77_threads.c, 352 threads/rfftwnd_threads.c, threads/rfftw_threads.h, 353 threads/rfftw_threads_test.c, configure.in, fftw/executor.c, 354 fftw/f77_func.h, fftw/fftwf77.c, fftw/fftw-int.h, fftw/fftwnd.c, 355 fftw/generic.c, fftw/malloc.c, fftw/planner.c, fftw/putils.c, 356 fftw/rader.c, fftw/timer.c, fftw/twiddle.c, fftw/wisdom.c, 357 fftw/wisdomio.c, gensrc/codelet_prelude, gensrc/config_prelude, 358 gensrc/rconfig_prelude, matlab/fftw.c, mpi/fftw_f77_mpi.h, 359 mpi/fftw_mpi.c, mpi/fftw_mpi.h, mpi/fftw_mpi_test.c, 360 mpi/fftwnd_mpi.c, mpi/rfftw_f77_mpi.c, mpi/rfftw_mpi.h, 361 mpi/rfftw_mpi_test.c, mpi/rfftwnd_mpi.c, mpi/TOMS_transpose.h: 362 whoops, kill acx_pthread test code 363 364Wed Feb 23 17:07:23 2000 fftw <fftw@fftw.org> 365 366 * mpi/README.f77: noted column-major slab decomposition 367 368Tue Feb 22 00:23:44 2000 Matteo Frigo <athena@fftw.org> 369 370 * doc/fftw.texi: Changed ``@iftex\\@tex\\@end tex\\@end iftex'' to 371 ``@tex\\@end tex'' because nesting is broken with texi2dvi-3.12 372 and texi2dvi-4.00. I don't know whether this is a texi2dvi bug or 373 our fault. (Nesting works properly if one does not use texi2dvi.) 374 375Mon Feb 14 19:41:37 2000 Matteo Frigo <athena@fftw.org> 376 377 * gensrc/rconfig_prelude: Removed copyright, because it is added 378 by makerconfig.sh. 379 380Fri Feb 11 07:15:05 2000 fftw <fftw@fftw.org> 381 382 * FAQ/fftw-faq.bfnn: Noted problems with DEC CC. Thanks to Xavier 383 Marduel for the bug report. 384 385Sun Feb 6 20:01:52 2000 fftw <fftw@fftw.org> 386 387 * gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am, 388 mpi/Makefile.am, threads/Makefile.am: Use $(srcdir)/foo instead of 389 $<, since according to GNU Makefile conventions document, many 390 non-GNU 'make' implementations only set $< for implicit rules. 391 392Thu Jan 27 16:18:03 2000 fftw <fftw@fftw.org> 393 394 * configure.in, gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am, 395 mpi/Makefile.am, threads/Makefile.am: Used $@, $< in Makefile 396 rules for srfftw.h, etcetera. This should fix things in VPATH 397 builds; thanks to Michael Poole for the suggestion. 398 399Wed Nov 10 20:01:40 1999 Steven G. Johnson <stevenj@fftw.org> 400 401 * threads/fftw_threads-int.h: Yikes! Self-#include should be 402 fftw_threads.h. 403 404Mon Nov 8 00:53:35 1999 Steven G. Johnson <stevenj@fftw.org> 405 406 * NEWS: noted (expected) 2.1.3 release date 407 408 * doc/texi2html, AUTHORS: Updated Matteo's email address. 409 410 * README: Noted mailing list URL. 411 412Sun Nov 7 19:15:52 1999 Steven G. Johnson <stevenj@fftw.org> 413 414 * doc/fftw.texi: Reference latest version of gcc bug report. 415 416 * acinclude.m4: Updated stack alignment check to also check for 417 misaligned main() (due to OS/libc/loader problems), and to 418 reference latest version of gcc bug report. 419 420Fri Nov 5 01:49:21 1999 Steven G. Johnson <stevenj@fftw.org> 421 422 * NEWS: Thanked Diab Jerius for CFLAGS patch. 423 424 * NEWS: noted that configure no longer overrides CFLAGS. 425 426 * acinclude.m4: Fixed code so that configure will not override the 427 CFLAGS environment variable. 428 429Tue Nov 2 23:52:02 1999 Steven G. Johnson <stevenj@fftw.org> 430 431 * rfftw/rfftwnd.c, doc/fftw.texi: Ugh, ugh, triple ugh! Had to 432 modify the rule for stride interpretation of in-place rfftwnd 433 transforms to handle a pathological case. Before, if you did 434 howmany transforms of size 1 (stride=1, dist=1) both the r2c and 435 c2r transforms would work okay, BUT: the input of the r2c 436 transform would have the required "padding" elements to make room 437 for the complex output, while the c2r transform would output real 438 numbers *without* padding (because of the idist==1 -> odist_t=1 439 rule). Thus, we'd have the bizarre situation of r2c + c2r = input 440 in different order (no padding). This caused the rfftwnd_mpi 441 tests to fail for Nx1 transforms (N > 2). So, I've modified the 442 rule slightly to idist==1 && idist < istride. This should 443 continue to make rfftwnd do what we want in all the ordinary 444 cases, but fixes this case. 445 446Mon Nov 1 22:31:14 1999 Steven G. Johnson <stevenj@fftw.org> 447 448 * NEWS: noted that gcc stack alignment bug was only on x86. 449 450Sun Oct 31 23:17:12 1999 Steven G. Johnson <stevenj@fftw.org> 451 452 * mpi/test_transpose_mpi.c: got rid of unused variables. 453 454 * mpi/test_sched.c: got rid of unused variable 455 456 * mpi/rfftw_f77_mpi.c: fixed typo 457 458 * configure.in: awk -F can't be followed by a space in older 459 awk's. 460 461 * mpi/Makefile.am: added README.f77 to distribution 462 463 * mpi/README.f77: minor fixes 464 465 * fortran/fftw_f77.i: changed "c" comments to "!" to accommodate 466 f90 freeform mode. Also added params for experimental MPI 467 wrappers. 468 469Fri Oct 29 21:41:59 1999 Steven G. Johnson <stevenj@fftw.org> 470 471 * mpi/README.f77, mpi/fftw_f77_mpi.h: minor additions to 472 documentation 473 474 * Makefile.am: disable autoheader here too (it was a problem once 475 today; why not before?) 476 477 * mpi/README.f77, NEWS: Added description of experimental MPI 478 wrappers. 479 480 * acinclude.m4, configure.in: Use AC_F77_LIBRARY_LDFLAGS when 481 attempting to link Fortran with C code in ACX_F77_FUNC_MANGLE. 482 483 * fftw/config.h.in, mpi/Makefile.am, mpi/fftw_f77_mpi.c, 484 mpi/fftw_f77_mpi.h, mpi/rfftw_f77_mpi.c, configure.in: Added 485 experimental Fortran-callable wrappers for the MPI transforms. 486 487 * acinclude.m4: small fix 488 489Thu Oct 28 19:53:33 1999 Steven G. Johnson <stevenj@fftw.org> 490 491 * doc/fftw.texi: Noted stack alignment bug in gcc 2.95.[012]. 492 493 * NEWS, acinclude.m4, configure.in: Work around buggy stack 494 alignment in gcc-2.95.x. 495 496 * acinclude.m4, configure.in: Reorganized macros in acinclude.m4 497 somewhat. New checks for -fstrict-aliasing and try to guess cpu 498 type on powerpc by looking at /proc/cpuinfo (using -mcpu=750 makes 499 a ~10% difference on a PowerPC G3). 500 501Tue Oct 26 21:45:06 1999 Steven G. Johnson <stevenj@fftw.org> 502 503 * tests/test_main.c: Added obligatory new joke for 2.1.3 release. 504 505 * threads/executor_threads.c, threads/rexec_threads.c, 506 rfftw/rexec.c, rfftw/rexec2.c, gensrc/to_c.ml, fftw/executor.c, 507 fftw/fftw-int.h: Technically, macros with empty argument lists 508 invoke undefined behavior in ANSI C, although they will be allowed 509 in the C99 language revision. Fix HACK_ALIGN_STACK_* macros to 510 remove this usage. 511 512 * fftw/config.h.in, fftw/fftw-int.h, doc/fftw.texi, configure.in: 513 --enable-i386-hacks is no longer needed in gcc-2.95+ 514 (i.e. versions which have the -mpreferred-stack-boundary flag). 515 516 * fftw/fftw-int.h: Indented alignment #preprocessor statements to 517 make them more readable. Also, made it so that you can use 518 --debug-alignment even without --enable-i386-hacks. 519 520Tue Oct 26 16:17:51 1999 Matteo Frigo <athena@fftw.org> 521 522 * ChangeLog: Updated ChangeLog 523 524Tue Oct 26 05:47:25 1999 Steven G. Johnson <stevenj@fftw.org> 525 526 * acinclude.m4: No point in doing both -mcpu and -mtune (-mcpu 527 includes -mtune). 528 529 * doc/fftw.texi: Some fixes in Fortran docs. 530 531 * rfftw/rexec.c, rfftw/rplanner.c, fftw/config.h.in, 532 fftw/executor.c, fftw/planner.c, configure.in: Vector recursion is 533 now enabled by a --enable-vec-recurse flag (disabled by default). 534 535 * NEWS: Added version number. 536 537Tue Sep 28 09:13:39 1999 Steven G. Johnson <stevenj@fftw.org> 538 539 * rfftw/rplanner.c, fftw/planner.c: Disable vector recursion for 540 now. 541 542 * fftw/rader.c, fftw/twiddle.c, fftw/config.h.in, fftw/fftw-int.h, 543 FAQ/fftw-faq.bfnn, NEWS, configure.in: Fixed overflow for (x*y)%p 544 in Rader routines (for complex transforms of prime sizes). Thanks 545 to Ezio Riva (ERiva@artis-software.com) for the bug report. 546 547Thu Aug 19 03:08:29 1999 Steven G. Johnson <stevenj@fftw.org> 548 549 * NEWS: Noted Matlab wrapper bug fix. 550 551Tue Aug 17 18:46:54 1999 Steven G. Johnson <stevenj@fftw.org> 552 553 * matlab/fftw.c: Fixed bug (memory leak; a new plan is created on 554 each call for the multi-dim. transforms). Thanks to Matthew 555 Davis <m.davis2@physics.ox.ac.uk> for the bug report. 556 557Wed Jul 28 19:12:15 1999 Steven G. Johnson <stevenj@fftw.org> 558 559 * NEWS, configure.in: Fixed configure script problems with 560 --enable-threads on Digital Unix. 561 562Tue Jul 27 20:03:22 1999 Steven G. Johnson <stevenj@fftw.org> 563 564 * fftw.spec.in: Many changes, including several based on 565 suggestions by Keith Amidon <camalot@picnicpark.org>. Now install 566 into the "build root" at build time so that building the RPM does 567 not affect existing FFTW installations (and doesn't require root 568 privileges). Compilation (and configuration) now only occurs 569 during the build phase. Post install and uninstall scripts run 570 ldconfig to update the linker database, and warn the user if the 571 install directory is not in /etc/ld.so.conf. Finally, the 572 double-precision libraries are installed into the standard [r]fftw 573 names instead of under d[r]fftw. 574 575 * tests/test_main.c: Minor cleanup. 576 577Sat Jul 24 20:32:58 1999 Steven G. Johnson <stevenj@fftw.org> 578 579 * tests/test_main.c, tests/test_main.h: Added -1 580 (--only-one-speed-test) option, as I'm tired of waiting for the 8 581 different speed tests to run when I only want one. 582 583 * threads/fftw_threads_test.c, threads/rfftw_threads_test.c, 584 tests/fftw_test.c, tests/rfftw_test.c, tests/test_main.c, 585 tests/test_main.h, rfftw/rplanner.c, mpi/fftw_mpi_test.c, 586 mpi/rfftw_mpi_test.c, fftw/fftw-int.h, fftw/fftw.h.in, 587 fftw/fftwnd.c, fftw/planner.c, fftw/putils.c, fftw/rader.c, 588 fftw/wisdom.c, fftw/wisdomio.c: Implemented new 589 FFTW_NO_VECTOR_RECURSE flag to inhibit use of vector recursion. 590 This flag is used internally in the planner to prevent vector 591 recursion at anything other than the top level of the plan 592 (instead of the planner_depth stuff used previously), and insures 593 that the correct wisdom is used. (Note, however, that the wisdom 594 is still not specific to the vector_size parameter; this needs to 595 be fixed.) 596 597Mon Jul 19 17:04:16 1999 Steven G. Johnson <stevenj@fftw.org> 598 599 * fftw/fftw-int.h: Added a comment about why we have macros for 600 trig. functions. 601 602Mon Jun 21 16:01:44 1999 fftw <fftw@fftw.org> 603 604 * FAQ/fftw-faq.bfnn: Noted that SGI MipsPro bugs seem to have been 605 fixed. Also mentioned problems with egcs-1.0.2 on the PowerPC. 606 607Sat Jun 19 17:47:28 1999 fftw <fftw@fftw.org> 608 609 * FAQ/fftw-faq.bfnn: Noted incorrect code generation in Metrowerks 610 CodeWarrior Pro 4 for the Macintosh. (Maybe we should rename this 611 FAQ question?) 612 613Fri Jun 18 19:20:28 1999 fftw <fftw@fftw.org> 614 615 * FAQ/m-html.pl: Updated FFTW Manual bookmark. 616 617Sat Jun 12 05:03:31 1999 fftw <fftw@fftw.org> 618 619 * doc/fftw.texi: Added clarifications to fftwnd reference, as 620 suggested by John F. Gibson of Cornell. 621 622Tue Jun 8 22:17:35 1999 fftw <fftw@fftw.org> 623 624 * threads/fftw_threads-int.h, tests/test_main.c, matlab/fftw.m, 625 gensrc/README, matlab/README, fftw/fftw-int.h, doc/fftw.texi, 626 FAQ/html.refs, FAQ/m-html.pl, cilk/README, FAQ/fftw-faq.bfnn, 627 TODO, fftw.spec.in, Makefile.am, README: Great URL change: web 628 page -> www.fftw.org, ftp -> ftp.fftw.org, email -> @fftw.org. 629 Note that currently, this means that some of links in the 630 documentation are broken (links to sub-pages within the main FFTW 631 site). This will be fixed once we get real hosting for fftw.org. 632 633Mon Jun 7 23:36:19 1999 fftw <fftw@fftw.org> 634 635 * fftw/config.h.in, fftw/fftw-int.h: Added warnings to flaky MacOS 636 nanosecond timer routines. (The ordinary Mac timer routines, with 637 microsecond accuracy (in theory) are okay.) 638 639Tue Jun 1 21:52:50 1999 fftw <fftw@fftw.org> 640 641 * fftw/fftw-int.h: Oops, I declared fftw_time twice. 642 643 * fftw/fftw-int.h: Incorporated new timer code by Sampo Niskanen. 644 645Mon May 31 17:45:34 1999 Matteo Frigo <athena@fftw.org> 646 647 * acinclude.m4: Added -arch host to osf-alpha CFLAGS. 648 649Sat May 29 20:38:03 1999 fftw <fftw@fftw.org> 650 651 * Makefile.am: slight reformatting. 652 653 * Makefile.am: Make sure lynx doesn't attempt to reformat logo gif 654 data. 655 656 * NEWS: Noted the date of each release (plus or minus a day or 657 two, in some cases). Merged release notes for beta releases with 658 those of final releases. 659 660Sat May 29 04:28:29 1999 Steven G. Johnson <stevenj@fftw.org> 661 662 * ChangeLog: ChangeLog now reflects all revisions of FFTW (instead 663 of starting at 6/11/98). 664 665 * ChangeLog: Updated change log. 666 667Sat May 29 03:25:59 1999 fftw <fftw@fftw.org> 668 669 * doc/fftw.texi: Fixed another typo. 670 671 * doc/fftw.texi: Typo fix. 672 673Fri May 28 19:33:41 1999 fftw <fftw@fftw.org> 674 675 * fftw.spec.in, Attic/fftw.spec, Makefile.am, configure.in: You 676 can now build the RPM package by running 'make rpm' (as root) 677 after 'make dist'. fftw.spec is now kept in sync automatically 678 with the version numbers in configure.in. 679 680Thu May 27 05:48:57 1999 fftw <fftw@fftw.org> 681 682 * threads/rexec_threads.c, rfftw/rplanner.c, 683 threads/executor_threads.c, rfftw/rexec2.c, rfftw/rfftw.h, 684 rfftw/rexec.c, fftw/rader.c, fftw/wisdom.c, fftw/putils.c, 685 fftw/planner.c, fftw/fftw.h.in, fftw/fftw-int.h, fftw/executor.c: 686 Initial version of "vector recursion" in executor. No vector 687 codelets yet. The threads code works, but does not do vector 688 recursion. No use of vector recursion for in-place howmany loops 689 yet. 690 691Wed May 26 18:06:47 1999 fftw <fftw@fftw.org> 692 693 * gensrc/complex.ml: In times_3_3 routine, got rid of infinite 694 loop for multiplication by non-constants (was biting us during 695 generation of twiddle codelets). 696 697 * gensrc/number.ml, gensrc/magic.ml, gensrc/genfft.ml, 698 gensrc/exprdag.ml, gensrc/complex.ml: Various cleanup 699 700 * tests/test_main.c, fftw/config.h.in, fftw/fftw.h.in: Centralized 701 tests for Windows (in config.h.in) and use HAVE_WIN32 elsewhere. 702 703Tue May 25 23:59:14 1999 fftw <fftw@fftw.org> 704 705 * NEWS: Removed extra period. 706 707 * doc/fftw.texi: Noted possibility of "d" or "s" prefix in the 708 tutorial (as requested by many users). 709 710 * FAQ/fftw-faq.bfnn, Attic/fftw.spec, NEWS, configure.in: Bumped 711 version number to 2.1.3, documented AIX threads fix. 712 713 * threads/fftw_threads-int.h, threads/fftw_threads.c, 714 fftw/fftw-int.h, configure.in, fftw/config.h.in, acinclude.m4: 715 Fixed threads bug on AIX: pthread_create on AIX spawns detached 716 (non-joinable) threads by default. Also fixed much autoconf 717 lossage on AIX. Thanks to Jim Lindsay (lindsay@mill.acns.nwu.edu) 718 for the bug report and for the use of Northwestern's SP2. 719 720 * fftw/timer.c: Only use BSDgettimeofday if gettimeofday is not 721 available (causes problems on some AIX systems). 722 723 * tests/rfftw_test.c, tests/fftw_test.c, rfftw/rplanner.c, 724 fftw/planner.c, fftw/fftw-int.h: Put (r)fftw_plan_hook in 725 fftw-int.h, with a typedef, and used Andrew Sterian's DL_IMPORT 726 macro to succor the lost souls using VC++. 727 728Fri May 21 17:58:30 1999 fftw <fftw@fftw.org> 729 730 * tests/test_main.c: Fixed typo in help string. 731 732Tue May 18 23:39:07 1999 fftw <fftw@fftw.org> 733 734 * threads/rfftw_threads_test.c, tests/test_main.h, 735 threads/fftw_threads_test.c, tests/test_main.c, 736 tests/rfftw_test.c, tests/fftw_test.c, mpi/rfftw_mpi_test.c, 737 mpi/fftw_mpi_test.c, FAQ/fftw-faq.bfnn, NEWS: Whoops, found the 738 real source of the MPI bug that was supposedly fixed in 2.1.2. 739 MPI_Init can modify argv (and does so, for processes other than 740 the first), but we passed the original argv to getopt. This is 741 now fixed. (This is a bug in the MPI test programs of 2.1.2 also, 742 but as it's only in the test programs and doesn't seem to bite us 743 on any known MPI implementation, it can wait until the next FFTW 744 release.) Sigh. 745 746Mon May 17 23:09:31 1999 fftw <fftw@fftw.org> 747 748 * NEWS: Went into more detail regarding the generator changes. 749 750Mon May 17 22:20:27 1999 Matteo Frigo <athena@fftw.org> 751 752 * NEWS: Note reduction in rfftw code size. 753 754 * gensrc/symmetry.ml, gensrc/genfft.ml, fftw/twiddle.c: Reduced 755 code size and # of operations of rfftw twiddle codelets. 756 757Mon May 17 19:57:11 1999 fftw <fftw@fftw.org> 758 759 * ChangeLog: Updated 760 761 * NEWS: Noted codelet generator speed. 762 763 * gensrc/symmetry.ml, gensrc/genfft.ml, gensrc/fft.ml: Improved 764 real{even|odd}2 transforms 765 766 * doc/fftw.texi: Fixed typo. 767 768 * gensrc/exprdag.ml: Improved simplifier for DCT-type transforms. 769 770 * TODO: Noted that the transpose routines for MPI could use 771 improving. 772 773 * gensrc/symmetry.ml: Fixed comment. 774 775 * gensrc/symmetry.ml, gensrc/genfft.ml, gensrc/fft.ml: Fixed 776 modified DCT/DST generation (realeven2/realodd2) so that it works 777 now. The simplifier really sucks for this, at the moment. Why? 778 779Sun May 16 23:59:33 1999 fftw <fftw@fftw.org> 780 781 * gensrc/genfft.ml: Fixed real[even,odd]2 codelet node type 782 output. 783 784 * gensrc/variable.ml, gensrc/variable.mli, gensrc/symmetry.ml, 785 gensrc/genfft.ml: Added generators realeven2 and realodd2 for the 786 modified DCT and DST (i.e. transforms for real data that are 787 even/odd about n=-1/2, not n=0). 788 789 * gensrc/exprdag.ml: Memoized eval for speed reasons. 790 791 * gensrc/util.ml, gensrc/exprdag.ml: Implemented better 792 statistics. 793 794 * gensrc/exprdag.ml: Improved complexity of network transposition 795 from O(n^2)=O(slow) to O(n) [times O(polylog)] 796 797 * TODO: Noted that the generator can now output efficient 798 hard-coded DCT/DST routines of small sizes. 799 800 * gensrc/variable.mli, gensrc/variable.ml, gensrc/symmetry.ml, 801 gensrc/genfft.ml, gensrc/complex.mli, gensrc/complex.ml: Added 802 realeven and realodd codelet generation options. (They work.) 803 804Mon May 10 02:48:14 1999 fftw <fftw@fftw.org> 805 806 * doc/fftw.texi: Noted how to force compiler choice via CC 807 env. variable. Also added "compiler" index entry. 808 809Fri May 7 20:12:11 1999 fftw <fftw@fftw.org> 810 811 * TODO, NEWS: Updated TODO. 812 813 * README: Fixed Cilk URL. 814 815 * NEWS: Noted GNU-style long options in the test programs. 816 817Thu May 6 22:35:05 1999 fftw <fftw@fftw.org> 818 819 * tests/test_main.c: --help option no longer causes an exit with 820 an error code. 821 822 * tests/test_main.c, configure.in, fftw/config.h.in: Test programs 823 now use GNU-ly correct long options if getopt_long is available. 824 825 * FAQ/fftw-faq.bfnn, NEWS: MPICH bug fix is apparently not 826 specific to Linux (it also fixed the same problem on some 827 Ultrasparcs). 828 829 * Attic/fftw.spec: Updated for 2.1.2. 830 831 * mpi/fftw_mpi_test.c: --only-parallel argument hack should also 832 only be accessed by process 0. 833 834Wed May 5 23:02:12 1999 fftw <fftw@fftw.org> 835 836 * NEWS: Noted addition of omitted fftw_f77_threads_init function. 837 838 * FAQ/fftw-faq.bfnn: Bug fix (dates need to have two digits for 839 the day). 840 841 * threads/rfftw_threads_test.c, threads/fftw_threads_test.c, 842 tests/test_main.c, tests/test_main.h, tests/rfftw_test.c, 843 tests/fftw_test.c, mpi/rfftw_mpi_test.c, mpi/test_transpose_mpi.c, 844 FAQ/fftw-faq.bfnn, mpi/fftw_mpi_test.c, NEWS, configure.in: Fixed 845 bug when running test programs under MPICH; prepared for 2.1.2 846 release. 847 848Sun Apr 18 04:16:39 1999 Steven G. Johnson <stevenj@fftw.org> 849 850 * Attic/fftw.spec: Made package relocatable. 851 852 * Attic/fftw.spec: Created spec file for generating RPM packages 853 of FFTW. 854 855 * FAQ/fftw-faq.bfnn: Revised linker FAQ entry. 856 857Mon Apr 12 19:34:17 1999 fftw <fftw@fftw.org> 858 859 * tests/test_main.c: Added joke. 860 861Sat Apr 10 00:14:37 1999 fftw <fftw@fftw.org> 862 863 * FAQ/fftw-faq.bfnn: Added linker FAQ entry. 864 865Wed Apr 7 17:17:48 1999 Steven G. Johnson <stevenj@fftw.org> 866 867 * threads/fftw_f77_threads.c: Added missing fftw_f77_threads_init 868 function (thanks to V. Sundararajan for pointing out the 869 omission). 870 871Tue Apr 6 19:29:13 1999 Steven G. Johnson <stevenj@fftw.org> 872 873 * configure.in: Check for hcc in addition to mpicc (hcc is used by 874 the LAM MPI implementation). 875 876Wed Mar 31 00:54:20 1999 Steven G. Johnson <stevenj@fftw.org> 877 878 * NEWS, doc/fftw.texi, ChangeLog: Fixed credit for 2.1.1 bug fix 879 (real credit goes to Ming-Chang Liu, according to Jeff 880 Briedenbach, whose name was misspelled anyway). 881 882Tue Mar 30 18:19:21 1999 Steven G. Johnson <stevenj@fftw.org> 883 884 * FAQ/fftw-faq.bfnn: Moderated language. 885 886 * NEWS: This isn't LaTeX, Matteo; an en dash in a monospaced font 887 is rendered the same as a hyphen (i.e. "-" not "--"). 888 889Mon Mar 29 19:23:24 1999 Matteo Frigo <athena@fftw.org> 890 891 * ChangeLog: Updated 892 893 * NEWS: Minor change. 894 895Sun Mar 28 20:24:30 1999 Matteo Frigo <athena@fftw.org> 896 897 * tests/rfftw_test.c, tests/fftw_test.c: Implemented paranoid 898 check for real->complex and complex->real transforms 899 900Sun Mar 28 00:11:47 1999 fftw <fftw@fftw.org> 901 902 * NEWS: Moderated language. I do not want to claim that the bug 903 occurs in `rare' circumstances. A bug is a bug, period. 904 905 * tests/fftw_test.c, rfftw/rplanner.c: Implemented paranoid check 906 for in-place complex planners. I still don't know how to check 907 real->complex plans, though (apart from rewriting test_ergun for 908 real->complex and complex->real) 909 910Fri Mar 26 22:58:57 1999 Steven G. Johnson <stevenj@fftw.org> 911 912 * doc/fftw.texi, FAQ/fftw-faq.bfnn, NEWS: Updated documentation 913 for FFTW 2.1.1. 914 915 * configure.in: Updated version number for 2.1.1 (as well as 916 shared lib. version). 917 918 * threads/Makefile.am, mpi/Makefile.am: Fixed typo in comment. 919 920 * threads/fftw_threads_test.c, threads/rfftw_threads_test.c, 921 mpi/rfftw_mpi_test.c, mpi/fftw_mpi_test.c: Added definition of 922 enter_paranoid_mode() to threads & MPI test programs. 923 924 * fftw/planner.c: Slight modification for future safety (not 925 necessary now). 926 927Thu Mar 25 02:29:08 1999 Matteo Frigo <athena@fftw.org> 928 929 * tests/test_main.c, tests/test_main.h, tests/rfftw_test.c, 930 tests/fftw_test.c, fftw/planner.c: Added hooks for paranoid 931 verification of every single plan. 932 933Tue Mar 23 17:44:35 1999 Matteo Frigo <athena@fftw.org> 934 935 * fftw/generic.c: Array read out of bounds---fixed. Thanks to 936 Jeff Breiden. 937 938Tue Mar 9 01:40:54 1999 Steven G. Johnson <stevenj@fftw.org> 939 940 * FAQ/fftw-faq.bfnn: Noted free-ness in "What is FFTW?" 941 description. 942 943Mon Mar 8 20:21:46 1999 Steven G. Johnson <stevenj@fftw.org> 944 945 * threads/fftw_threads.c: By default, don't even try to specify 946 PTHREAD_SCOPE_SYSTEM, since it causes problems on @!#%$ IRIX 6.5 947 (in which PTHREAD_SCOPE_SYSTEM is not supported, but 948 pthread_attr_setscope doesn't return an error!!!). Just use the 949 default attributes (fftw_pthread_attributes_p == NULL). 950 951 * threads/fftw_threads.c: Fixed typo in comment. 952 953 * NEWS: Added 2.1 news. 954 955Mon Mar 8 18:00:37 1999 fftw <fftw@fftw.org> 956 957 * tests/rfftw_test.c, tests/fftw_test.c: Fixed pow(8192, x) --> 958 pow(8192.0, x) . This failed on Digital unix, I don't know why. 959 960Mon Mar 8 15:16:51 1999 Matteo Frigo <athena@fftw.org> 961 962 * ChangeLog: Updated 963 964 * configure.in: Updated version number 965 966Sun Mar 7 19:47:54 1999 Steven G.

Johnson <stevenj@fftw.org> 1042 1043 * FAQ/fftw-faq.bfnn: Noted workaround for buggy SGI compilers. 1044 1045 * ChangeLog: Line-wrapped (I wish you would remember to do this, 1046 Matteo). 1047 1048 * gensrc/Makefile.rfftw.am, mpi/Makefile.am, threads/Makefile.am, 1049 gensrc/Makefile.fftw.am: Got rid of hackery in header creation, 1050 since circular dependencies are gone. Also added prefixed headers 1051 to CLEANFILES so they get deleted by 'make clean'. 1052 1053 * configure.in: Used xyz for prefix1 instead of just x, to make 1054 future conflicts less likely. 1055 1056Mon Feb 22 18:55:16 1999 Matteo Frigo <athena@fftw.org> 1057 1058 * configure.in: Fix for irix didn't work, let's try this 1059 1060 * ChangeLog: Fixed typo 1061 1062 * ChangeLog: Updated 1063 1064 * configure.in: Accounted for irix thread lossage 1065 1066 * tests/test_main.c: usage() must normally exit, otherwise the 1067 test programs tries to read argv[] out of bounds. 1068 1069 * doc/Makefile.am: fftw.ps used compressed fonts 1070 1071 * gensrc/Makefile.rfftw.am, gensrc/Makefile.fftw.am: rfftw.h 1072 didn't go into distribution. Fixed 1073 1074 * threads/Makefile.am, gensrc/Makefile.rfftw.am, mpi/Makefile.am, 1075 configure.in, gensrc/Makefile.fftw.am: Removed circular 1076 dependencies 1077 1078 * configure.in: Fixed typo 1079 1080Mon Feb 22 05:19:40 1999 Steven G. Johnson <stevenj@fftw.org> 1081 1082 * tests/test_main.c: Added some new jokes.

(Also got rid of some extraneous 1089 newlines printed by mpi code.) 1090 1091 * configure.in, NEWS: Renamed 2.1 -> 2.1-beta1. 1092 1093 * doc/Makefile.am: make clean shouldn't remove rfftwnd.gif. 1094 1095Sun Feb 21 20:33:51 1999 Steven G. Johnson <stevenj@fftw.org> 1096 1097 * NEWS: Feature set for 2.1 is now frozen (I think). 1098 1099 * doc/fftw.texi: slight change 1100 1101 * mpi/Makefile.am, threads/Makefile.am, gensrc/Makefile.fftw.am, 1102 gensrc/Makefile.rfftw.am: Whoops! Don't include 1103 XXX_FFTW_PREFIX_XXX header files in CLEANFILES, because that will 1104 cause 'make clean' to delete irreplaceable files when no prefix is 1105 being used. 1106 1107 * mpi/Makefile.am, threads/Makefile.am, gensrc/Makefile.fftw.am, 1108 gensrc/Makefile.rfftw.am: Fixed installed headers to use 1109 FFTW_PREFIX for their own header inclusions. 1110 1111 * configure.in, doc/fftw.texi, NEWS: Documented 1112 --enable-type-prefix. 1113 1114 * mpi/Makefile.am, tests/Makefile.am, threads/Makefile.am, 1115 gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am, acinclude.m4, 1116 configure.in: Use FFTW_PREFIX for all installed files. 1117 1118 * configure.in: Use g77 in preference to fort77. 1119 1120Sun Feb 21 17:56:49 1999 Matteo Frigo <athena@fftw.org> 1121 1122 * tests/Makefile.am: Fixed forgotted XXX_FFTW_NAME_XXX 1123 1124 * configure.in: Allowed user specification of [r]fftw-name 1125 1126Sun Feb 21 17:35:28 1999 fftw <fftw@fftw.org> 1127 1128 * tests/Makefile.am, configure.in, gensrc/Makefile.fftw.am, 1129 gensrc/Makefile.rfftw.am, acinclude.m4: (Preliminary) hack: allow 1130 user to change name of fftw library. 1131 1132 * configure.in: Incremented shared library version number. 1133 1134 * configure.in: Added rfftw_mpi.h to list of files to install for 1135 --enable-mpi. 1136 1137Sat Feb 20 23:00:41 1999 Steven G. Johnson <stevenj@fftw.org> 1138 1139 * FAQ/fftw-faq.bfnn: The ascii and info (but not html) versions of 1140 the FAQ were chopping off the answer to the last question. Rather 1141 than fix the bug, I just added a trailing comment like in the 1142 Linux FAQ, which seems to correct the problem. 1143 1144 * FAQ/fftw-faq.bfnn: Minor fixes and updates for 2.1. 1145 1146 * mpi/rfftw_mpi_test.c, mpi/fftw_mpi.h, mpi/fftw_mpi_test.c, 1147 mpi/fftw_mpi.c: Share plans between forward and backward fftw_mpi 1148 plans (and between other fftw_mpi plans of the same size). 1149 1150 * tests/rfftw_test.c, tests/fftw_test.c: In -p test with rank > 1, 1151 reduce the size of the arrays for the plan. 1152 1153 * mpi/transpose_mpi.c: Got rid of compiler warning (code was okay, 1154 though). 1155 1156 * doc/fftw.texi: small fix. 1157 1158Sat Feb 20 03:27:36 1999 fftw <fftw@fftw.org> 1159 1160 * doc/fftw.texi: Minor tweaks 1161 1162Sat Feb 20 02:57:37 1999 Steven G. Johnson <stevenj@fftw.org> 1163 1164 * doc/Makefile.am, doc/rfftwnd.gif: fig2dev gif output stinks; 1165 "manually" add better version of gif figure. 1166 1167 * doc/fftw.texi: Added link. 1168 1169 * doc/Makefile.am: Make sure to distribute rfftwnd.fig. 1170 1171 * doc/fftw.texi: Some post-reorganization grooming. 1172 1173 * configure.in: Whoops! Use $enableval, not $withval, in 1174 AC_ARG_ENABLE. 1175 1176Fri Feb 19 23:50:45 1999 Matteo Frigo <athena@fftw.org> 1177 1178 * doc/Makefile.am, doc/fftw.texi: Added picture to postscript 1179 manual 1180 1181Fri Feb 19 23:29:07 1999 fftw <fftw@fftw.org> 1182 1183 * configure.in: Added fort77 to list of fortran compiler (linux 1184 f2c comes with a program with this name) 1185 1186 * doc/rfftwnd.gif, doc/rfftwnd.fig, doc/Makefile.am: 1187 Reverse-engineered rfftwnd picture from postscirpt to fig, so I 1188 can edit it and produce smaller postscript. (Linux rules!) 1189 1190 * doc/fftw.texi: Restructured manual 1191 1192Fri Feb 19 20:32:13 1999 Steven G. Johnson <stevenj@fftw.org> 1193 1194 * fftw/config.h.in, threads/fftw_threads-int.h, configure.in, 1195 doc/fftw.texi, NEWS: Added untested support for Mach C threads. 1196 Also changed three --with options to --enable. 1197 1198Fri Feb 19 17:22:38 1999 Matteo Frigo <athena@fftw.org> 1199 1200 * threads/rfftw_threads_test.c, threads/rfftwnd_threads.c, 1201 threads/rexec2_threads.c, threads/rexec_threads.c, 1202 threads/rfftw_threads.h, threads/fftw_threads_test.c, 1203 threads/fftwnd_threads.c, threads/fftw_threads.c, 1204 threads/fftw_threads.h, threads/executor_threads.c, 1205 threads/fftw_threads-int.h, tests/test_main.c, tests/fftw_test.c, 1206 tests/rfftw_test.c, rfftw/rgeneric.c, rfftw/rplanner.c, 1207 rfftw/rfftwf77.c, rfftw/rfftwnd.c, rfftw/rexec2.c, rfftw/rfftw.h, 1208 mpi/transpose_mpi.c, rfftw/rexec.c, mpi/sched.h, mpi/test_sched.c, 1209 mpi/test_transpose_mpi.c, mpi/rfftw_mpi_test.c, mpi/rfftwnd_mpi.c, 1210 mpi/sched.c, mpi/fftwnd_mpi.c, mpi/rfftw_mpi.h, mpi/fftw_mpi.c, 1211 mpi/fftw_mpi.h, mpi/fftw_mpi_test.c, mpi/TOMS_transpose.h, 1212 matlab/fftw.c, mpi/TOMS_transpose.c, gensrc/variable.ml, 1213 gensrc/variable.mli, gensrc/util.mli, gensrc/twiddle.ml, 1214 gensrc/util.ml, gensrc/to_c.mli, gensrc/symmetry.ml, 1215 gensrc/to_c.ml, gensrc/schedule.ml, gensrc/schedule.mli, 1216 gensrc/number.mli, gensrc/rconfig_prelude, gensrc/magic.ml, 1217 gensrc/number.ml, gensrc/fft.ml, gensrc/genfft.ml, 1218 gensrc/exprdag.mli, gensrc/expr.ml, gensrc/expr.mli, 1219 gensrc/exprdag.ml, gensrc/dag.ml, gensrc/dag.mli, 1220 gensrc/complex.ml, gensrc/complex.mli, gensrc/asched.mli, 1221 gensrc/ast.ml, gensrc/asched.ml, fftw/wisdomio.c, 1222 fortran/f77_test.F, fftw/twiddle.c, fftw/wisdom.c, fftw/rader.c, 1223 fftw/timer.c, fftw/planner.c, fftw/putils.c, fftw/generic.c, 1224 fftw/malloc.c, fftw/fftwf77.c, fftw/fftwnd.c, fftw/fftw-int.h, 1225 fftw/fftw.h.in, fftw/executor.c, fftw/f77_func.h, 1226 fftw/config.h.in, cilk/time_cilk.cilk, doc/fftw.texi, 1227 cilk/fftwnd_cilk.cilk, cilk/test_cilk.cilk, 1228 cilk/executor_cilk.cilk, cilk/fftw_cilk.cilkh, COPYRIGHT, 1229 ChangeLog: Fixed copyright year 1230 1231Fri Feb 19 06:12:37 1999 Steven G.

The new implementation is almost completely 1367 rewritten from before, and should (hopefully) be easier to manage 1368 and (maybe) faster in some cases. 1369 1370 * configure.in: Check for pthread_create outside of -lpthread, 1371 since some systems may have threads built into the standard C 1372 libraries. 1373 1374 * fftw/malloc.c: Allow allocation/freeing of 0-size blocks/NULL 1375 pointers (since that is ANSI-okay, after all). 1376 1377 * cilk/executor_cilk.cilk: Use ntwiddle instead of r-1 in case 1378 twiddle policy changes. 1379 1380 * mpi/Attic/time_fftwnd_mpi.c: Whoops! don't pass uninitialized 1381 out parameter (shouldn't be a problem in any case since transform 1382 is in-place, but better safe than sorry). 1383 1384Thu Feb 11 02:31:45 1999 Steven G. Johnson <stevenj@fftw.org> 1385 1386 * doc/fftw.texi: Noted necessity of linking threads-using code 1387 with -lpthread or whatever. 1388 1389 * rfftw/rfftwf77.c, fortran/Attic/rfftw_f77.c, 1390 fortran/Attic/fortranize.h, fortran/Attic/fftw_f77.c, 1391 fortran/fftw_f77.i, fortran/Attic/README, fortran/f77_test.F, 1392 fftw/f77_func.h, fftw/fftwf77.c, fftw/config.h.in, configure.in, 1393 doc/fftw.texi, NEWS, acinclude.m4: Fortran wrapper functions are 1394 now automatically included in the main FFTW libraries, unless the 1395 --without-fortran option is passed to configure. They are also 1396 documented in the main manual. 1397 1398 * doc/fftw.texi: Fixed broken cross-reference. 1399 1400Wed Feb 10 22:47:01 1999 Steven G.

Johnson <stevenj@fftw.org> 1441 1442 * tests/test_main.c: Noted -x and -f options in -h help. 1443 1444 * threads/executor_threads.c: Yikes! Use ntwiddle instead of r-1 1445 in twiddle_thread. (This would have been a problem if we ever 1446 changed the twiddle policy.) 1447 1448 * threads/fftwnd_threads.c, threads/executor_threads.c, 1449 threads/fftw_threads-int.h, fftw/config.h.in: Use autoconf to 1450 determine if alloca is available and use malloc/free if it is not. 1451 1452 * threads/fftw_threads_test.c: Call fftw_threads_init when 1453 starting up. 1454 1455 * threads/Attic/time_threads.c, threads/Attic/test_threads.c, 1456 threads/fftwnd_threads.c, threads/fftw_threads.h, 1457 threads/fftw_threads_test.c, threads/executor_threads.c, 1458 threads/fftw_threads-int.h, threads/fftw_threads.c, 1459 threads/Attic/README, threads/Makefile.am, tests/test_main.c, 1460 tests/test_main.h, tests/rfftw_test.c, configure.in, 1461 tests/fftw_test.c: Made the threads test program follow the model 1462 of the uniprocessor test programs. 1463 1464 * doc/fftw.texi: Documented --with-threads configure option. 1465 1466 * threads/Attic/time_threads.c, threads/Attic/README, 1467 threads/Attic/test_threads.c, threads/Makefile.am, 1468 threads/fftw_threads.h, threads/Attic/Makefile, configure.in, 1469 fftw/config.h.in, Makefile.am, NEWS: Autoconfiscated threads 1470 stuff. 1471 1472Mon Feb 1 18:49:40 1999 fftw <fftw@fftw.org> 1473 1474 * FAQ/fftw-faq.bfnn: Added entry about VC++ 5.0 1475 1476Fri Jan 29 01:11:15 1999 Steven G.

The linear system was converging to 0 in 1519 floating point, and it caused underflow problems. 1520 1521Wed Oct 7 16:15:39 1998 Steven G. Johnson <stevenj@fftw.org> 1522 1523 * configure.in: Fixed usage of ` in echo. 1524 1525Tue Oct 6 04:46:04 1998 Steven G.

This is almost completely 1919 portable because of the new alloca() trick. Code is much cleaner 1920 now. 1921 1922 * doc/fftw.texi: Described rfftwnd complex format, and discussed 1923 meaning of stride/dist for in-place transforms. 1924 1925Wed Aug 26 23:08:05 1998 fftw <fftw@fftw.org> 1926 1927 * fftw/rader.c, fftw/planner.c, cilk/test_cilk.cilk, 1928 cilk/executor_cilk.cilk, cilk/Makefile, ChangeLog: Upgraded Cilk 1929 version to 2.0 1930 1931 * doc/fftw.texi: Fixed a couple of typos 1932 1933 * doc/fftw.texi: Added most of rfftwnd reference. 1934 1935 * NEWS: Noted FFTW_THREADSAFE and corresponding new section of the 1936 manual. 1937 1938 * doc/fftw.texi: More changes in the introduction of the 1939 halfcomplex format. 1940 1941 * doc/fftw.texi: Made it clear that halfcomplex applies to 1942 one-dimensional rfftw only. 1943 1944 * doc/texi2html: There is no <MATH> tag in HTML 4.0. 1945 1946 * doc/fftw.texi: Fixed html versions of halfcomplex dfn. 1947 1948 * doc/texi2html, doc/fftw.texi: Added a few missing html formulas 1949 1950 * doc/fftw.texi: Some minor changes.

The hack 1977 now should work across all generations of gcc/egcs, whether 1978 building a shared library or not. 1979 1980 * doc/fftw.texi: Noted use of fast algorithm for prime sizes in 1981 complex transforms. Got rid of <MATH> tag everywhere (doesn't 1982 seem to be well-defined in the HTML standard). 1983 1984 * rfftw/rfftw.h: Changed rfftw.h to reflect the manual. 1985 1986 * rfftw/rexec.c, fftw/fftw-int.h, fftw/executor.c, 1987 fftw/config.h.in, configure.in: Changed the x86 hack to work also 1988 with the shared library. 1989 1990 * doc/texi2html: @math used to translate to italics, which looked 1991 ugly in HTML; now does nothing. 1992 1993 * doc/fftw.texi: Several small changes.

Emacs 2067 texinfo-mode is great! 2068 2069 * doc/fftw.texi: Re-added "Words of Wisdom" and "Multi-Dimensional 2070 Array Formats" chapters Added chapter on parallel transforms & 2071 thread-safety. 2072 2073 * doc/texi2html: @url{} tags are now converted into hyperlinks. 2074 2075Fri Aug 21 17:24:36 1998 fftw <fftw@fftw.org> 2076 2077 * gensrc/util.mli, gensrc/util.ml, gensrc/symmetry.ml, 2078 gensrc/fft.ml: Fixes to improve speed of generator and op count 2079 for n not squarefree. 2080 2081Thu Aug 20 22:35:04 1998 fftw <fftw@fftw.org> 2082 2083 * doc/fftw.texi: Grammar fix. 2084 2085 * doc/fftw.texi: Don't need to say the number of args. 2086 2087 * doc/fftw.texi: Recommend that quick starts be read in order. 2088 2089 * rfftw/rfftwnd.c: dist parameter for in-place transforms now 2090 works more closely like what you might expect. 2091 2092 * doc/fftw.texi: Various fixes and modifications. 2093 2094 * doc/fftw.texi: Added rfftwnd quick start. 2095 2096 * doc/fftw.texi: public-domain -> freely-available (FFTW, along 2097 with many other FFT routines, is not "public-domain"). 2098 2099 * doc/fftw.texi: Minor additions. 2100 2101 * doc/fftw.texi: Wrote rfftw quick start. 2102 2103 * fftw/twiddle.c, fftw/rader.c: Use FFTW_FORWARD instead of a 2104 hard-coded negative sign, in case someone ever needs to change 2105 this sign. 2106 2107 * rfftw/rfftw.h: Recreated rfftw_plan and rfftwnd_plan types. 2108 2109 * doc/fftw.texi: Some more changes to the multi-dimensional 2110 quick-start. 2111 2112 * doc/fftw.texi: Added quick-start for multi-dimensional 2113 transforms. 2114 2115 * doc/fftw.texi: Added 1d complex quick start. 2116 2117Wed Aug 19 23:55:39 1998 fftw <fftw@fftw.org> 2118 2119 * doc/fftw.texi: Changed reference in the introduction--an 2120 introductory book is a better reference for people who don't know 2121 anything about DFTs. Also some minor changes. Alluded to a 2122 License and Copyright section. 2123 2124 * gensrc/symmetry.ml, gensrc/magic.ml, gensrc/fft.ml, 2125 gensrc/exprdag.mli, gensrc/exprdag.ml, gensrc/expr.mli, 2126 gensrc/expr.ml: Implemented three-phase simplifier. 2127 2128 * gensrc/symmetry.ml, gensrc/magic.ml, gensrc/fft.ml: Reset 2129 rader_min to 13, until I understand how to simplify the code 2130 properly. 2131 2132 * gensrc/number.ml, gensrc/magic.ml, gensrc/genfft.ml, 2133 gensrc/fft.ml, gensrc/exprdag.mli, gensrc/exprdag.ml, 2134 gensrc/Makefile.sources, gensrc/Makefile.genfft: Disabled new 2135 convolution hack for n >= 17, since the naive algorithm is better. 2136 The hack is similar to Rader's variant 4 in Tolimieri's book, and 2137 the growth of the operation count is also documented in that book. 2138 2139 * TODO: Updated to reflect the fact that we have now rewritten 2140 rfftw. 2141 2142 * fortran/Attic/README: Fixed erroneous listing of rfftwnd. 2143 2144 * fortran/Attic/fortranize.h, fortran/Attic/README: Various 2145 improvements. 2146 2147 * NEWS: Added rfftw Fortran wrappers. 2148 2149 * fortran/Attic/fortranize.h, fortran/Attic/rfftw_f77.c, 2150 fortran/fftw_f77.i, fortran/Attic/fftw_f77.c, 2151 fortran/Attic/README: Added rfftw wrappers. 2152 2153Tue Aug 18 23:52:19 1998 fftw <fftw@fftw.org> 2154 2155 * gensrc/exprdag.ml, gensrc/expr.ml, gensrc/Makefile.genfft: 2156 Another horrible hack in the generator speeds up n=13 by a lot. 2157 2158 * rfftw/Attic/rfftwint.h: Whoops! Deleted extraneous characters. 2159 2160 * rfftw/rplanner.c, rfftw/rgeneric.c, rfftw/rfftwnd.c, 2161 rfftw/Attic/rfftwint.h, rfftw/rfftw.h, rfftw/rexec2.c, 2162 rfftw/rexec.c, gensrc/Makefile.rfftw.am: Added invoke_many routine 2163 for rfftw, and split hacks into separate header file (rfftwint.h). 2164 2165 * gensrc/magic.ml, gensrc/genfft.ml, gensrc/fft.ml, 2166 gensrc/exprdag.ml, gensrc/Makefile.sources: Implemented new way of 2167 doing Rader's algorithm. 2168 2169 * NEWS: Noted fftw_one, etcetera. 2170 2171 * ChangeLog: Line-wrapped entries. 2172 2173 * tests/rfftw_test.c, rfftw/rfftwnd.c: Yikes! Bug fix. In the 2174 future, be sure to try running the test program with the -m 2175 option, since the rfftwnd specific planner operates signficantly 2176 differently under FFTW_MEASURE than under FFTW_ESTIMATE. 2177 2178Mon Aug 17 23:27:23 1998 fftw <fftw@fftw.org> 2179 2180 * tests/test_main.c: Also sprach g++: the `gets' function is 2181 dangerous and should not be used. 2182 2183 * rfftw/rfftwnd.c, fftw/rader.c, fftw/malloc.c: Made g++ happy 2184 2185 * rfftw/rplanner.c, fftw/putils.c, ChangeLog: Fixed wrong 2186 arguments in make_node_rgeneric. (Ouch!) 2187 2188 * tests/rfftw_test.c, tests/fftw_test.c, rfftw/rfftwnd.c, 2189 fftw/fftwnd.c, fftw/fftw.h.in, fftw/fftw-int.h: Added 2190 FFTW_THREADSAFE flag, which is intended to guarantee that the plan 2191 be read-only, making it safe to use the same plan in parallel from 2192 multiple threads. Currently, it only has an effect in the 2193 multi-dimensional transforms (the 1d plans are already read-only). 2194 2195 * tests/Makefile.am, rfftw/rfftw.h, rfftw/rexec2.c, rfftw/rexec.c, 2196 fftw/executor.c: Optimized the aligned _many loop. Fixed 2197 alignments in rexec2.c 2198 2199 * rfftw/rexec.c, fftw/fftw-int.h, fftw/executor.c: Reorganized 2200 alignment hacks to be more robust with different compilers and 2201 compiler flags. 2202 2203 * tests/Makefile.am: automake TESTS variable expects the names of 2204 actual executables, not simple 'make' dependencies. Fixed by 2205 overriding 'make check' behavior instead of using TESTS. 2206 2207 * tests/test_main.c, tests/Makefile.am: Added 'make check' 2208 feature, along with flag to test programs to limit the number of 2209 iterations. 2210 2211 * tests/test_main.h, tests/test_main.c, tests/rfftw_test.c, 2212 tests/fftw_test.c, rfftw/rfftwnd.c, rfftw/rfftw.h, rfftw/rexec.c, 2213 fftw/fftwnd.c, fftw/fftw.h.in, fftw/executor.c: Added fftw_one and 2214 friends, and modified the test programs to check them. 2215 2216 * doc/fftw.texi: Capitalization changes, clarifications, and other 2217 minor changes. 2218 2219 * doc/texi2html, doc/fftw.texi: Restructured manual (still 2220 incomplete) 2221 2222 * rfftw/rplanner.c, rfftw/rgeneric.c, rfftw/rfftw.h, 2223 rfftw/rexec.c, fftw/twiddle.c, fftw/timer.c, fftw/rader.c, 2224 fftw/putils.c, fftw/planner.c, fftw/malloc.c, fftw/generic.c, 2225 fftw/fftwnd.c, fftw/fftw-int.h, fftw/executor.c, fftw/config.h.in: 2226 Many cosmetic changes. ``optimized'' rexecutor slightly. 2227 2228 * fftw/rader.c: Calls fftw_executor_simple directly instead of 2229 calling fftw(). 2230 2231 * tests/test_main.h, tests/test_main.c, tests/rfftw_test.c: Fixed 2232 (hopefully) a problem with roundoff errors sometimes exceeding the 2233 tolerance. 2234 2235Sun Aug 16 22:55:43 1998 fftw <fftw@fftw.org> 2236 2237 * rfftw/rgeneric.c: ``optimized'' rgeneric codelets (kind of) 2238 2239 * fftw/fftw-int.h, fftw/config.h.in, configure.in: Added separate 2240 --enable-debug-alignment flags for debugging x86 alignments (the 2241 --enable-debug flag also changes the compiler flags, which we 2242 don't want to do). 2243 2244 * rfftw/rplanner.c, fftw/putils.c: Bug fix--make sure to only call 2245 rgeneric codelets for odd n. 2246 2247 * rfftw/rexec2.c, gensrc/Makefile.sources: Fixed x86 alignments. 2248 2249 * tests/test_main.c: -s now interacts with -d 1 in the same way 2250 that -c and -a do. 2251 2252 * NEWS: Slight clarification. 2253 2254 * rfftw/rplanner.c: Planner can now decide on the best place to 2255 use generic codelets. 2256 2257 * fftw/planner.c: Planner now decides the best place to put 2258 generic/Rader codelets. 2259 2260 * fftw/putils.c: Changed message for Rader print_plan. 2261 2262 * tests/rfftw_test.c, fftw/rader.c, fftw/putils.c, fftw/fftw.h.in: 2263 Modified Rader to use only a single plan for forward and backward 2264 transforms of the convolution. 2265 2266Sat Aug 15 22:35:05 1998 fftw <fftw@fftw.org> 2267 2268 * NEWS: Noted the news. 2269 2270 * threads/Attic/Makefile, tests/Makefile.am, mpi/Attic/Makefile, 2271 matlab/Makefile, gensrc/config, gensrc/README, fftw/fftw-int.h, 2272 doc/fftw.texi, cilk/README, cilk/Makefile, FAQ/fftw-faq.bfnn, 2273 configure.in, README.hacks, Makefile.am, INSTALL: The great 2274 directory renaming: src -> fftw. 2275 2276 * fftw/twiddle.c, fftw/rader.c, fftw/putils.c, fftw/fftw.h.in, 2277 fftw/fftw-int.h, fftw/executor.c: Added sharing of Rader data and 2278 twiddles between different plans (and within the same plan). 2279 2280 * tests/test_main.c, fftw/malloc.c, fftw/fftw.h.in: When debugging 2281 is enabled, keep track of the peak memory usage (and report it in 2282 the test programs). 2283 2284 * fftw/rader.c: Rader is now prepared to share data between 2285 forward and backward transforms. 2286 2287 * fftw/rader.c, fftw/fftw.h.in, fftw/fftw-int.h, fftw/executor.c: 2288 Whoops, forgot to add rader.c to the repository. Also got rid of 2289 an unused variable and include prototypes for the *_ops functions 2290 in fftw-int.h. 2291 2292 * fftw/twiddle.c, fftw/putils.c, fftw/planner.c, fftw/fftw.h.in, 2293 fftw/fftw-int.h, fftw/executor.c, gensrc/Attic/Makefile.am: Added 2294 Rader codelets to handle large prime factors. 2295 2296Fri Aug 14 23:37:20 1998 fftw <fftw@fftw.org> 2297 2298 * rfftw/rgeneric.c: rgeneric seems to work! 2299 2300 * rfftw/rgeneric.c: Fixed yet another bug in rgeneric. 2301 2302 * rfftw/rexec.c: Fixed wrong union field. 2303 2304 * fftw/putils.c, fftw/planner.c, fftw/fftw.h.in, fftw/fftw-int.h, 2305 rfftw/rplanner.c, rfftw/rgeneric.c, rfftw/rexec.c, 2306 gensrc/Makefile.rfftw.am: Implemented generic codelet.

(It's working 2316 now...hooray!) 2317 2318 * tests/test_main.h: CHECK now calls fftw_die instead of exit 2319 (mainly to make it easier to breakpoint). 2320 2321 * fftw/wisdom.c, fftw/twiddle.c, fftw/timer.c, fftw/putils.c, 2322 fftw/planner.c, fftw/malloc.c, fftw/generic.c, fftw/fftwnd.c, 2323 fftw/fftw.h.in, fftw/fftw-int.h, fftw/config.h.in, 2324 fftw/.indent.pro, rfftw/rplanner.c, rfftw/rfftwnd.c, 2325 rfftw/rfftw.h, rfftw/.indent.pro, gensrc/.indent.pro: Moved code 2326 around to avoid unnecessary linking dependencies. 2327 2328 * tests/rfftw_test.c, fftw/putils.c, fftw/planner.c, 2329 fftw/generic.c, fftw/fftw-int.h, fftw/.indent.pro, 2330 rfftw/rplanner.c, rfftw/rfftwnd.c, rfftw/rfftw.h, rfftw/rexec2.c, 2331 rfftw/rexec.c, rfftw/.indent.pro, gensrc/Attic/Makefile.am, 2332 gensrc/.indent.pro: Splitted planner.c into two files, so that the 2333 liker does not load the complex codelets if only rfftw is used. 2334 Renamed rfftw_plan->fftw_plan, since they are the same and we do 2335 not seem able to maintain consistency internally. 2336 2337 * ChangeLog: Updated changelog 2338 2339 * fftw/executor.c, rfftw/rexec2.c: Removed redundant test 2340 2341 * tests/rfftw_test.c, rfftw/rfftwnd.c: Fixed more bugs in in-place 2342 rfftwnd (not done yet...sigh). 2343 2344 * rfftw/rfftwnd.c, rfftw/rexec2.c, rfftw/rexec.c: Fixed bug in 2345 rfftwnd for ((n+1)/2)%4 == 0. 2346 2347Thu Aug 13 23:56:16 1998 fftw <fftw@fftw.org> 2348 2349 * rfftw/rexec2.c: Removed redundant statement. 2350 2351 * tests/test_main.c: test -d 1 -a now uses nd routines, consistent 2352 with -d 1 -c <n>. 2353 2354 * fftw/malloc.c: Need to flush(stdout) before printing to stderr, 2355 or messages sometimes come in the wrong order. Also, should pass 2356 EXIT_FAILURE instead of 1 to exit(). 2357 2358 * fftw/executor.c, rfftw/rexec.c: Fixed those damned alignments. 2359 2360 * tests/test_main.h, tests/test_main.c, tests/rfftw_test.c, 2361 tests/fftw_test.c: Multi-dimensional tests are getting closer to 2362 working... 2363 2364 * rfftw/rfftwnd.c, rfftw/rexec2.c: Bug fixes. 2365 2366 * fftw/fftw-int.h, fftw/executor.c, rfftw/rexec.c, gensrc/to_c.ml, 2367 gensrc/magic.ml, gensrc/genfft.ml, gensrc/Makefile.sources: Added 2368 automatic alignment checker --- this will make life easier on the 2369 x86 2370 2371 * fftw/wisdom.c: Fixed incorrect order of arguments. 2372 2373 * fftw/wisdom.c, fftw/twiddle.c, fftw/planner.c, fftw/fftw-int.h, 2374 fftw/executor.c, fftw/.indent.pro, rfftw/rplanner.c, 2375 rfftw/rfftwnd.c, rfftw/rexec2.c, rfftw/rexec.c, rfftw/.indent.pro, 2376 configure.in: Added extra wisdom flag.

Also, cleaned up the 2822 please_wait routine and called it in more places. 2823 2824Mon Apr 6 23:29:21 1998 fftw <fftw@fftw.org> 2825 2826 * TODO: fixed typo 2827 2828 * tests/fftw_test.c: minor fix 2829 2830 * tests/fftw_test.c, fftw/fftw-int.h, fftw/config.h.in, 2831 doc/fftw.texi, configure.in: Added pentium timer and jokes 2832 2833 * fftw/wisdom.c, fftw/fftw.h.in, fftw/fftw-int.h, 2834 gensrc/genfft.ml, configure.in: Minor fixes 2835 2836 * tests/fftw_test.c, fftw/wisdom.c, tests/Attic/Makefile.in, 2837 fftw/planner.c, fftw/fftw.h.in, fftw/executor.c, 2838 rfftw/Attic/test_rfftw.c, rfftw/Attic/Makefile.in, 2839 gensrc/genfft.ml, gensrc/Attic/Makefile.in, configure.in, TODO: 2840 fixed wisdom + minor details 2841 2842Sun Apr 5 17:28:03 1998 fftw <fftw@fftw.org> 2843 2844 * doc/fftw.texi: In Quick Start, reminded readers that they need 2845 to compile and install FFTW. 2846 2847 * doc/fftw.texi: Casted malloc results in example code for C++ 2848 compatibility. 2849 2850 * Attic/RELEASE-NOTES: Noted threads improvements. 2851 2852 * threads/fftw_threads.h: Fixed missing close paren in comment. 2853 2854 * threads/fftw_threads.h, threads/Attic/README: Added experimental 2855 Win32 threads support. 2856 2857 * threads/fftwnd_threads.c: Used recursive fftwnd, adapted from 2858 new serial version.
