Description

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?
