https://github.com/xianyi/OpenBLAS/releases

  OpenBLAS will now provide enough buffer space for at
  least 50 threads by default.

GotoBLAS2 1.13 BSD version and further extended.
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
