Invalid user id #43

Closed LorenzoKonig closed 4 years ago

LorenzoKonig commented 4 years ago

Describe the issue When running a python script via mpiexec on the Alan CPUs an error "invalid user id: 1049" occurs. When I submit it without mpiexec it is generating the output as expected.

To Reproduce My submit.sh file:

#!/bin/bash #SBATCH --job-name=OPGtests #SBATCH --output=optical_propagation_tests.txt #SBATCH --ntasks=4 #SBATCH --time=59:00 #SBATCH --mem-per-cpu=100 mpiexec -n 4 python finite_HWP.py

And the output file contains only:

srun: fatal: Invalid user id: 1049

Note that the job continues running but no further output is generated. I noticed that Malavika experienced the same error message a couple of months ago, although in a different context (Issue #41 )

Additional Context I have a python environment activated to run Meep simulations (optical propagation) in parallel using mpirun / mpiexec. Please let me know if you need more detailed information. Thanks!

It is possible that the provisioning script has not been executed when your account was added. I'll check this.

Hi @LorenzoULG

Can you try again? I'll give your jobs priority to test this.
