AOCL-ScaLAPACK is a library of high-performance linear algebra routines for parallel distributed memory machines. It can be used to solve linear systems, least squares problems, eigenvalue problems, and singular value problems. AOCL-ScaLAPACK is optimized for AMD “Zen”-based processors. It depends on the external libraries BLAS and LAPACK; thus, the use of AOCL-BLAS and AOCL-LAPACK is recommended.
