Introduction

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

What is atlas

The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort f(ocusing on applying empirical techniques in order to provide portable performance. At present, it provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK. The performance improvements in ATLAS are obtained largely via compile-time optimizations and tend to be specific to a given hardware configuration. In order to package ATLAS some compromises are necessary so that good performance can be obtained on a variety of hardware. This set of ATLAS binary packages is therefore not necessarily optimal for any specific hardware configuration. However, the source package can be used to compile customized ATLAS packages; see the documentation for information. atlas 3.10.3 8.el8 x86_64 6.4 M atlas-3.10.3-8.el8.src.rpm baseos Automatically Tuned Linear Algebra Software http BSD The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort f(ocusing on applying empirical techniques in order to provide portable performance.

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

Install atlas 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:

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

sudo yum -y install atlas

How To Uninstall atlas on CentOS 8

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

sudo dnf remove atlas
