How To Install ga-openmpi on CentOS 8
Introduction
In this tutorial we learn how to install ga-openmpi on CentOS 8.
What is ga-openmpi
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. - Libraries against OpenMPI.
We can use yum or dnf to install ga-openmpi on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install ga-openmpi.
Install ga-openmpi 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:

Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install ga-openmpi using dnf by running the following command:
sudo dnf -y install ga-openmpi
Install ga-openmpi on CentOS 8 Using yum

After updating yum database, We can install ga-openmpi using yum by running the following command:
sudo yum -y install ga-openmpi
How To Uninstall ga-openmpi on CentOS 8
To uninstall only the ga-openmpi package we can use the following command:
sudo dnf remove ga-openmpi
