Hello,
We use OneAPI on IBM Spectrum LSF environment.
Now we are facing that "mpirun -np 2 -ppn 1 ./mpi-program.out" does not work.
It always run all processes on same node.
LSF support said it is not related LSF.
What does it caused by ?
And how do we investigate this issue ?

Hi TobiasK,
Thank you for your reply and big hint.
I got this output with I_MPI_DEBUG=10 and I_MPI_HYDRA_DEBUG=1.
Both I_MPI_JOB_RESPECT_PROCESS_PLACEMENT and ppn = 1 specified, defaulting to scheduler-supplied value.
-ppn worked fine by specified I_MPI_JOB_RESPECT_PROCESS_PLACEMENT=disable.
We appreciate for your kind support.
