or:

module load gcc openmpi-gcc

for OpenMPI programs.

There are many versions of the GNU compilers installed on Artemis. To see what versions are available, run the following command:

module avail |& grep gcc

The following table shows the various commands to use when compiling code, depending on the language and style of execution being used:
