I think I know how many ppn one nodes have. :-) My question was that the number of ppn has something to do with the PME mesh part number or not?
Why sometimes I had a big load imbalance.

Regarding the nodes ask your administrator how many ppn one node have. example suppose if one node has 6 ppn then 12 nodes will have 72ppn which is sufficient to run md. hope the above explanation helps you.

Before I did those kind of very blindly, just based on the most nodes I can use to hopefully run quickly.
