How To Install pmix on Fedora 36

In this tutorial we learn how to install pmix in Fedora 36. pmix is Process Management Interface Exascale (PMIx)

Introduction

In this tutorial we learn how to install pmix on Fedora 36.

What is pmix

The Process Management Interface (PMI) has been used for quite some time as a means of exchanging wireup information needed for interprocess communication. Two versions (PMI-1 and PMI-2) have been released as part of the MPICH effort. While PMI-2 demonstrates better scaling properties than its PMI-1 predecessor, attaining rapid launch and wireup of the roughly 1M processes executing across 100k nodes expected for exascale operations remains challenging. PMI Exascale (PMIx) represents an attempt to resolve these questions by providing an extended version of the PMI standard specifically designed to support clusters up to and including exascale sizes. The overall objective of the project is not to branch the existing pseudo-standard definitions - in fact, PMIx fully supports both of the existing PMI-1 and PMI-2 APIs - but rather to (a) augment and extend those APIs to eliminate some current restrictions that impact scalability, and (b) provide a reference implementation of the PMI-server that demonstrates the desired level of scalability.

We can use yum or dnf to install pmix on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install pmix.

Install pmix on Fedora 36 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

After updating yum database, We can install pmix using dnf by running the following command:

sudo dnf -y install pmix

Install pmix on Fedora 36 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

After updating yum database, We can install pmix using yum by running the following command:

sudo yum -y install pmix

How To Uninstall pmix on Fedora 36

To uninstall only the pmix package we can use the following command:

sudo dnf remove pmix
