PLEIADES

User documentation for the PLEIADES cluster at the University of Wuppertal

PGI is superseded by the NVHPC module, but both approaches should work.

PGI

PGI provides tools to develop programs in a heterogeneous environment (CPUs & GPUs):

The PGI license is made available through the HPC.NRW Kompetenznetzwerk.

Setup

The PGI license is currently only available on our fugg1 node. Connect to it from within the university network via

ssh fugg1.pleiades.uni-wuppertal.de

Additionally you need to setup your user environment:

export PGI="/beegfs/pgi"
export PATH="${PGI}/linux86-64/20.4/bin":$PATH
export MANPATH=$MANPATH:"${PGI}/linux86-64/20.4/man"
export LM_LICENSE_FILE=$LM_LICENSE_FILE:"${PGI}/license.dat"

This can also be done via

source /beegfs/pgi/scripts/setup.sh

Consider putting this into your bashrc, if you have to call it regularly!

Small Fortran Test

To check if the compilers work, lets create a small Fortran program hello.f90:

print *, "Hello world"
end

Now compile and execute it via:

pgfortran -o hello hello.f90
./hello

Additional Resources

Get an overview of possible command line options via the man pages, e.g. man pgfortran or through the -help flag. (not -h or --help!)

There is a lot of information on the PGI page as well:
