Returns an array with the mpi compiler and the source code located in /data/hpc

relogin_root

When subroutine returns immediately returns 1 to indicate that no relogin has occurred.

compare_mpi_versions

compare_mpi_versions($package_name, $package_version, $another_package_version);

Given an HPC package, compare package_version against another_package_version. The default behavior is to compare any given another_package_version with the installed version. In that case package_version is determined in runtime.
