OpenBLAS is an optimized open-source implementation of the BLAS (Basic Linear Algebra Subprograms) library, based on GotoBLAS2, with LAPACK included. It provides fast, hand-tuned linear algebra kernels for many CPU architectures.
Use cases
- speed up matrix multiplication in scientific computing
- fast linear algebra backend for numpy or scipy
- optimized BLAS routines for machine learning workloads
- solve linear systems and eigenvalue problems with LAPACK
- build numerical applications needing tuned kernels per CPU architecture
When to choose
- you need a fast, free BLAS/LAPACK implementation across many platforms and CPU architectures
- you want a drop-in replacement for reference netlib BLAS with much better performance
- you are building numerical, scientific, or ML software that depends on BLAS
When to avoid
- you need GPU-accelerated linear algebra (consider cuBLAS or similar)
- you only need simple matrix math without performance tuning (a higher-level library may suffice)
- you need a pure high-level API rather than low-level BLAS/LAPACK routines
