Package Information

Description:
OpenBLAS is an optimized Basic Linear Algebra Subprograms (BLAS) library based on GotoBLAS2 1.13 BSD version. It was forked when Mr. Kazushige Goto left TACC and GotoBLAS became unmaintained. In general, BLAS is the computational kernel ("the bottom of the food chain") in linear algebra or scientific applications. Thus, if your BLAS implementation is highly optimized, the whole application can substantially benefit. OpenBLAS has optimized code for modern architectures, and has accrued many other features and bug fixes beyond GotoBLAS.
