How To Install qrmumps on CentOS 7
Introduction
In this tutorial we learn how to install qrmumps on CentOS 7.
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.
We can use yum or dnf to install qrmumps on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install qrmumps.
Install qrmumps on CentOS 7 Using yum
Update yum database with yum using the following command.
sudo yum makecache
After updating yum database, We can install qrmumps using yum by running the following command:
sudo yum -y install qrmumps
Install qrmumps on CentOS 7 Using dnf
If you don’t have dnf installed you can install DNF on CentOS 7 first.
Update yum database with dnf using the following command.
sudo dnf makecache
After updating yum database, We can install qrmumps using dnf by running the following command:
sudo dnf -y install qrmumps
How To Uninstall qrmumps on CentOS 7
To uninstall only the qrmumps package we can use the following command:
sudo dnf remove qrmumps
