OpenBLAS : An optimized BLAS library (original) (raw)

OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version. Please read the documents on OpenBLAS wiki.

Binary Packages

We strive to provide binary packages for the following platform.

• Windows x86/x86_64/arm64 (hosted on sourceforge.net; if required the mingw runtime dependencies can be found in the 0.2.12 folder there)
  Note that while the binaries may be slow to arrive on sourceforge.net at the moment, they can also be found in the Releases section of the github site,https://github.com/OpenMathLib/OpenBLAS/releases. Binaries for other platforms are usually available on the sites listed in the OpenBLAS Wiki

Install from Source

Please read User Manual and Installation Guide

Full project documentation (that also covers topics like installing from source) is available here - this builds on and will eventually replace the wiki
