Result Summary Different For Jobs With Different Numbers of Nodes
I've been running some benchmarks using MPI and I have noticed that when the jobs complete the summary is displayed in a different way depending on how many nodes I use.
For a two node job:
Core t (s) Wall t (s) (%) Time: 151386.697 3153.890 4800.0 52:33 (ns/day) (hour/ns) Performance: 0.044 546.867 Finished mdrun on rank 0 Thu Jun 7 15:12:51 2018
And for a 256 node job:
Core t (s) Wall t (s) (%) Time: 960396.768 156.315 614400.0 (ns/day) (hour/ns) Performance: 0.885 27.104 Finished mdrun on rank 0 Wed Nov 15 06:26:15 2017
What is the significance of the "52:33" which is displayed for the 2 node job and not the 256 node job?
