Optimized Basic Linear Algebra Subprograms library.
OpenBLAS supplies BLAS routines and an included LAPACK implementation for applications that need numerical linear algebra. Developers link the library into their programs, using packaged binaries or builds configured with Make or CMake. Builds can target a particular CPU or include multiple targets within an architecture for runtime selection, and threading controls let applications configure the library’s worker count.
