Here post your question
I am testing the performance over 20 nodes in a HPC. I submit job through pbs and end the program after 2 min, sometimes log files do not contains perforamce report. especially when i add more number of nodes. Can someone can tell me why it is so?
Example:
Running on 25 nodes with total 1700 cores, 6800 logical cores
Cores per node: 68
Logical cores per node: 272
Last part is
Intra-simulation communication will occur every 20 steps.
There are: 338569 Atoms
Atom distribution over 960 domains: av 352 stddev 27 min 307 max 402
Center of mass motion removal mode is Linear
We have the following groups for center of mass motion removal:
0: SOLU_MEMB
1: SOLV
