This is indeed strange, as it first detects the correct allocation. And it conforms to the one granted.
- You used a plain `mpiexec` without and number of processes or machinesfile?
[eg: ] I'm using orterun and i'm ony providing the number of process. Shouldn't I ?
- Can you please post while it's running the relevant lines from:
ps -e f --cols=500
(f w/o -) from both machines.
It's allocated between the nodes more like in a round-robin fashion.
[eg: ] I'll try to do this tomorrow, as soon as some slots become free. Thanks for your feedback Reuti, I appreciate.
