PE layout diagram: Always show largest/ending process number

[sarats]

To find the number of nodes, first look at the Processor # / Simulation Time chart on PACE. The furthest right number on that chart is the number of processors - 1 (because of zero-indexing), so add one to get the number of processors. Divide that number by MPI tasks/node in the “Experiment Details” section. The result will be the number of nodes.

In some cases, the largest process number is not listed.
