Package: raxml Version: 7.2.8-2 Severity: wishlist Dear Maintainer,
the current RAxML package contains only the "vanilla" version of RAxML compiled without support threading or SIMD. Given that typical use cases of RAxML require days of computation, enabling parallel processing would improve the utility of the package significantly. RAxML does not detect the available hardware at runtime. Instead, separate Makefiles build the various optimized versions. Supported SIMD variants are: (none), SSE3, AVX and AVX2. Supported threading variants are: (none), PTHREADS, MPI and HYBRID (both pthreads and MPI). The makefile names are "Makefile.<SIMD-TYPE><THREAD-TYPE>gcc". Since most users will have multi-core CPUs and only very few a MPI environment, focusing on the PTHREAD variants with SIMD extensions should be a good balance between package complexity and extra value. The AVX2 extensions apparently do not add much performance. Therefore, I would suggest building three versions: - Makefile.PTHREADS.gcc - Makefile.PTHREADS.SSE3.gcc - Makefile.PTHREADS.AVX.gcc (depends >= gcc 4.6) A simple bash wrapper script could then be used to make the appropriate choice for the user. E.g.: ---- #!/bin/bash if grep -q avx /proc/cpuinfo; then exec raxml.PTHREADS.AVX "$@" elif grep -q sse3 /proc/cpuinfo; then exec raxml.PTHREADS.SSE3 "$@" else exec raxml.PTHREADS.NOSIMD "$@" fi ---- best regards, Elmar -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
