> module avail openmpi openmpi/2.1.1--gnu--6.1.0 openmpi/1.8.4--intel--cs-xe-2015--binary openmpi/1.8.5--pgi--15.3
> module load gnu openmpi/1.8.4--gnu--4.9.2 > man mpif90 > mpif90 -o myexec myprof.f90 (uses the gfortran compiler) > module purge > module load intel openmpi/1.8.4--intel--cs-xe-2015--binary > man mpif90 > mpif90 -o myexec myprof.f90 (uses the ifort compiler) > module purge > module load pgi openmpi/1.8.5--pgi--15.3 > man mpif90 > mpif90 -o myexec myprof.f90 (uses the pgf90 compiler)
In all cases the parallel applications have to be executed with the command:
