Install: brew install flexiblas

About:
FlexiBLAS is a unified BLAS and LAPACK interface wrapper library designed for high-performance computing environments. It allows users to dynamically switch between different optimized BLAS backends (like OpenBLAS, Intel MKL, or ATLAS) at runtime without recompiling applications. This flexibility simplifies performance tuning and dependency management across diverse hardware architectures.

Key Features:

Runtime exchangeable backend interfaces
Drop-in replacement for standard BLAS/LAPACK
Support for multiple backend providers simultaneously
Low overhead wrapper design

Use Cases:

Optimizing linear algebra performance on heterogeneous clusters
Managing BLAS dependencies in scientific software stacks
Benchmarking different BLAS implementations without recompilation

Alternatives:

OpenBLAS – OpenBLAS is a specific optimized implementation, while FlexiBLAS provides a wrapper layer to switch between implementations including OpenBLAS.
Intel MKL – MKL is a proprietary high-performance library; FlexiBLAS can use MKL as a backend but offers vendor-neutral abstraction.
