Several versions of Gromacs are available, check below:

Compilation details:

For example Gromacs 2022.6 was patched with Plumed 2.8.3 and compiled with the GNU 8.3.0 tool chain and OpenMPI 3.1.6. The GPU enabled version was compiled with CUDA SDK (software development kit) 12.0.0 and is usable with CUDA RTL (run time library) 12.0.0. Code was generated for CUDA architecture 6.0, 7.0, 8.0.

Supported CUDA architectures:

Environment modules are available in different flavors:

To define the GMXLIB environment variable, add the following lines to the file $HOME/.bash_profile:

GMXLIB=$HOME/gromacs/top
 
export GMXLIB
