Package: libnvblas9.2 Version: 9.2.148-1 Severity: wishlist X-Debbugs-CC: debian-scie...@lists.debian.org
Nvidia says nvBLAS is a "drop-in" BLAS library however it merely provides several level-3 BLAS symbols. That being said, nvBLAS is indeed a valid candidate for libblas.so.3 if explicitly specified by the user. The priority chain should look like this: OpenBLAS (40) > BLIS (37) > Atlas (35) > Netlib (10) > MKL (1) > nvBLAS (-100) - BLIS is still not avaialble in Debian. - The fastest BLAS implementation MKL has priority 1 because it's non-free. - nvBLAS has priority (-100) because (1) it's non-free (2) requires nvidia card (3) requires config file. Apart from that, nvBLAS also needs an configuration file, unlike other blases. I got a significant speed boost in octave following[2]. That means to some extent nvBLAS should be added to the libblas.so.3 candidate list.
