OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version. The BLAS (Basic Linear Algebra Subprograms) are routines that provide standard building blocks for performing basic vector and matrix operations. The Level 1 BLAS performs scalar, vector and vector-vector operations, the Level 2 BLAS performs matrix-vector operations, and the Level 3 BLAS performs matrix-matrix operations. Because the BLAS are efficient, portable, and widely available, they are commonly used in the development of high-quality linear algebra software, LAPACK for example. The reference BLAS is included inside the LAPACK package. Please refer to tools built under Windows using Cmake the cross-platform, open-source build system. The new build system was developed in collaboration with Kitware Inc. Machine-specific optimized BLAS libraries are available for a variety of computer architectures. These optimized BLAS libraries are provided by the computer vendor or by an independent software vendor.
Features
- OpenBLAS is licensed under the 3-clause BSD license
- Simply invoking make (or gmake on BSD) will detect the CPU automatically
- Requires a C compiler, e.g. GCC or Clang
- Requires a Fortran compiler (optional, for LAPACK)
- Compile with MASS support on Power CPU
- The IBM MASS library consists of a set of mathematical functions for C, C++
