I've recently started running multi-host parallel NWCHEM runs. I would like to confirm what sort of scaling I am getting.
Is it sufficient to look at the 'Task Times' as reported in the .out file & calculate the ratio of Cpu vs. Wall time as an estimate this? Or does one really have to run the same benchmark job on different number of nodes and compare the Wall time?
I'm not looking for accurate figures - just a check to make sure I'm not squandering CPU!
