Running jobs


Frequently asked questions related to running jobs in the queue system on the HPC clusters (currently: Fram and Saga).

"srun: Warning: can't honor --ntasks-per-node set to X which doesn't match the requested tasks Y with the number of requested nodes Y. Ignoring --ntasks-per-node."

This warning appears when using the mpirun command with Intel MPI and specifying --ntasks-per-node for jobs in the normal partition on Fram. As far as we have seen, the job does not ignore the --ntasks-per-node, and will run the specified number of processes per node. You can test it with, e.g., mpirun hostname. Please let us know if you have an example where --ntasks-per-node is not honored!

So, if you get this when using mpirun with Intel MPI, our recommendation is currently that the warning can be ignored.
