    ScaLAPACK is a library of high-performance linear algebra routines
    for parallel distributed memory machines. It depends on external
    libraries including BLAS and LAPACK for Linear Algebra computations.

    AMD's optimized version of ScaLAPACK enables using BLIS and
    LibFLAME library that have optimized dense matrix functions and
    solvers for AMD EPYC processor family CPUs.
