Task and submission

...

1. Use the input under testsuite/isc2023 folder.

2. Profile the input
   Use any of the remote clusters to run an MPI profile (such as IPM profile or any other profiler) over 4 nodes, full PPN to profile the given input.

   • Submit the profile as PDF to the team's folder.

   • Add to your presentation the 3 main MPI calls that are being used plus the MPI time being used.

3. Run the POT3D with isc2023 input on both PSC bridges-2 and FAU Fritz CPU clusters.

4. Submission and Presentation:
   - Submit all the build scripts, run scripts and input & outputs (pot3d.dat, pot3d.out, timing.out)
   - Do not submit HDF5 outputs or the source code.
   - Prepare slides for the team’s interview based on your work for this application.
