Hi, before making an official cygwin package for OpenBlas (fast Blas) http://www.openblas.net/
I would like some test from potential users. The dynamic library is multicore, so it should work on "all" processors, but unfortunately I can only test on my dual Core i5-3320M. On this system the speedup of basic BLAS operation is notable. 1000x1000x1000 DGEMM tests give for x86_64 architecture 0.818047 s 2444.847301 MFLOPS x86_64 netlib reference 0.055000 s 36363.636364 MFLOPS x86_64 openblas 2.12 for i686 architecture 0.825001 s 2424.239486 MFLOPS i686 netlib reference 0.095001 s 21052.409975 MFLOPS i686 openblas 2.12 Libraries are available on: http://matzeri.altervista.org/x86/openblas/libopenblas_dynamic/ http://matzeri.altervista.org/x86_64/openblas/libopenblas_dynamic/ To use them is enough to copy the cygblas-0.dll in any path directory before "/usr/lib/lapack" where the lapack one is located. On http://matzeri.altervista.org/works/openblas/ there is also a DGEMM test routine, if you have no other benchmark.
