How To Install ga-openmpi-static on CentOS 8

ga-openmpi-static is Global Arrays Toolkit for OpenMPI Static Libraries

Introduction

In this tutorial we learn how to install ga-openmpi-static on CentOS 8.

What is ga-openmpi-static

The Global Arrays (GA) toolkit provides an efficient and portable “shared-memory” programming interface for distributed-memory computers. Each process in a MIMD parallel program can asynchronously access logical blocks of physically distributed dense multi- dimensional arrays, without need for explicit cooperation by other processes. Unlike other shared-memory environments, the GA model exposes to the programmer the non-uniform memory access (NUMA) characteristics of the high performance computers and acknowledges that access to a remote portion of the shared data is slower than to the local portion. The locality information for the shared data is available, and a direct access to the local portions of shared data is provided. - Static Libraries against OpenMPI.

We can use yum or dnf to install ga-openmpi-static on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install ga-openmpi-static.

Install ga-openmpi-static on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:
