Unlike the openmpi and mvapich2 modules, mvapich2-gdr does not adapt itself to the currently loaded compiler and CUDA modules. This version of the software was built using GCC 8.4.1 and CUDA 11.3.
However, gcc 8.4.1 is not a module, there is 8.4.0 and native which currently maps to an install of 8.5.0.
