How To Install qrmumps on Fedora 34

qrmumps is A multithreaded multifrontal QR solver A multithreaded multifrontal QR solver

Introduction

In this tutorial we learn how to install qrmumps on Fedora 34.

What is `qrmumps`

qr_mumps is a software package for the solution of sparse, linear systems on multicore computers. It implements a direct solution method based on the QR factorization of the input matrix. Therefore, it is suited to solving sparse least-squares problems and to computing the minimum-norm solution of sparse, underdetermined problems. It can obviously be used for solving square problems in which case the stability provided by the use of orthogonal transformations comes at the cost of a higher operation count with respect to solvers based on, e.g., the LU factorization. qr_mumps supports real and complex, single or double precision arithmetic. qrmumps 3.0.2 1.fc34 x86_64 315 k qrmumps-3.0.2-1.fc34.src.rpm updates A multithreaded multifrontal QR solver http LGPLv3+ qr_mumps is a software package for the solution of sparse, linear systems on multicore computers.

We can use yum or dnf to install qrmumps on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install qrmumps.

Install qrmumps on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

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

sudo dnf -y install qrmumps

Install qrmumps on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

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

sudo yum -y install qrmumps

How To Uninstall qrmumps on Fedora 34

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

sudo dnf remove qrmumps
