Feature: Possibility to suppress slaves from output

When using large number of CPU e.g 720+, each execution of utility prints slaves.

-should this printing be optional ?

On/off would be the first improvement. Could also consider allowing other integer values for collating by host (with pids, or simply the count per host).

Any thoughts about this for a compromise. Report slave information, but in a more compact form? Code attached as patch.

looks good, but any limitation on number of cpus of any node printed over line?

e.g. 24 cpus of node1

"node1" (1 ... 24)

No line length imposed. I'm not sure how important the pids are anyhow. We could readily just print out the number of processes per node (as yet another selectable option).

Eg,

      nProcs : 18
      Slaves :
      (
          (node1 6)
          (node2 8)
          (node1 3)
      )

Or

      nProcs : 18
      Slaves :
      (
          (6 node1)
          (8 node2)
          (3 node1)
      )

Looks good. I like the 3 choices (print pids, collate per node, suppress) For 2 my preference is

      nProcs : 18
      Slaves :
      (
          (node1 6)
          (node2 8)
          (node1 3)
      )

• pids is only important if something goes wrong
• but knowing the nodes that are have been used is nice. Quite a few customer problems come from e.g. oversubscribing or using nodes that have problems

That is what I was thinking too. When collating with count, maybe makes more sense to include the master node in the count list too. This is a better indication of the subscription. Of course, shouldn't be labeled as Slaves in that case, but Hosts or Procs
