How To Install psblas3-openmpi on Rocky Linux 8

In this tutorial we learn how to install psblas3-openmpi on Rocky Linux 8. psblas3-openmpi is OpenMPI psblas3

Introduction

In this tutorial we learn how to install psblas3-openmpi on Rocky Linux 8.

What is `psblas3-openmpi`

The PSBLAS library, developed with the aim to facilitate the parallelization of computationally intensive scientific applications, is designed to address parallel implementation of iterative solvers for sparse linear systems through the distributed memory paradigm. It includes routines for multiplying sparse matrices by dense matrices, solving block diagonal systems with triangular diagonal entries, preprocessing sparse matrices, and contains additional routines for dense matrix operations. The current implementation of PSBLAS addresses a distributed memory execution model operating with message passing. This is a OpenMPI PSBLAS version.
