How To Install libvma on CentOS 8

libvma is A library for boosting TCP and UDP traffic (over RDMA hardware)

Introduction

In this tutorial we learn how to install libvma on CentOS 8.

What is libvma

libvma is a LD_PRELOAD-able library that boosts performance of TCP and UDP traffic. It allows application written over standard socket API to handle fast path data traffic from user space over Ethernet and/or Infiniband with full network stack bypass and get better throughput, latency and packets/sec rate. No application binary change is required for that. libvma is supported by RDMA capable devices that support “verbs” IBV_QPT_RAW_PACKET QP for Ethernet and/or IBV_QPT_UD QP for IPoIB.

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

Install libvma on CentOS 8 Using dnf

Update yum database with dnf using the following command.
