OpenBLAS is licensed under the 3-clause BSD license. HOMEPAGE http://www.openblas.net/ CYGWIN NOTES 1) As BLAS it is around 5-10 times faster than Netlib reference, included in the liblapack0 package. 2) No devel package is provided as liblapack-devel already provide the needed headers and import. Openblas is fully compatible with Netlib BLAS. 3) libopenblas consist of a single file /usr/bin/cygblas-0.dll that will precede in PATH the liblapack0 /usr/lib/lapack/cygblas-0.dll and used instead. Removing libopenblas will restore the usage of Netlib BLAS 4) CPU architecture covered up to now 64 bit ATOM BARCELONA BOBCAT BULLDOZER CORE2 DUNNINGTON EXCAVATOR HASWELL NANO NEHALEM OPTERON OPTERON_SSE3 PENRYN PILEDRIVER PRESCOTT SANDYBRIDGE STEAMROLLER ZEN 32 bit ATHLON ATOM BANIAS BARCELONA BOBCAT COPPERMINE CORE2 DUNNINGTON KATMAI NANO NEHALEM NORTHWOOD OPTERON OPTERON_SSE3 PENRYN PRESCOTT 5) Built with a max number of 16 threads; it should be enough to fully utilize up a 8 core dual thread. The fixed max limit at build time is a upstream limitation, if you need more than 16 let me know.
