So, you are running on 80+ core machines then?

    Well, AIX runs on mainframes, and IBM System z mentions 141 cores per frame. I've never worked with such a machine, so I can't tell whether you can use them all easily.

      Agreed. Several of my projects have been destined to run on Power 8 architecture with upto 192 processors; but such expensive systems rarely give all their resources over to a single job.

      What I was attempting to determine is how near to "launch simultaneously" the OP needed. If all start within a few seconds is good enough, it's pretty simple. If it's all start at exactly the same time, it's possible, but requires a different approach.

      In the absence of evidence, opinion is indistinguishable from prejudice.
