How To Install gromacs on CentOS 8
Introduction
In this tutorial we learn how to install gromacs on CentOS 8.
What is gromacs
GROMACS is a versatile and extremely well optimized package to perform molecular dynamics computer simulations and subsequent trajectory analysis. It is developed for bio-molecules like proteins, but the extremely high performance means it is used also in several other field like polymer chemistry and solid state physics. This package provides single and double precision binaries. The documentation is in the package gromacs-common. mdrun has been compiled with thread parallellization, so it runs in parallel on shared memory systems. If you want to run on a cluster, you probably want to install one of the MPI parallellized packages. N.B. All binaries have names starting with g_, for example mdrun has been renamed to g_mdrun.
