The following scenario:
an LPAR wirth 5 CPs and single zIIP. Some HPU job causes 100%
utilization of zIIP, other HPU tasks wait until zIIP gets free cycles.
What's strange IMHO: the jobs do not try to consume CP cycles.
It's good, because of SCRT reports, from the other hand it's bad,
because
Yes, IIPHONORPRIORITY is your way to allow or disallow zIIP work to be run on
CPs in scenarios as you describe.
