# Scratch Memory Allocation (Microbenchmark)

This code sample aims to benchmark the performance of the scratch memory allocation. This facility is a viable option to satisfy the need for temporary memory when using the DNN domain of LIBXSMM (small convolutions).  Although any kind of readable/writable buffer can be bound to a convolution handle, LIBXSMM's `libxsmm_aligned_scratch` features a thread-safe linear allocator mechanism which can help to lower allocation overhead.
