I'm certain that CFCC would provide an excellent soaker workload. I just
wouldn't try to use that coupling LPAR for anything!

more and no less than 4/32 of the total CPU is wasted running a silly
loop.
Whatever's not used by the loop is available to the other LPARs. Warn
capacity planners and resource billing people that there's a "soaker"
workload.
I don't get it! Is this "soaker" some sort of stand-alone IPLable
program you've written? Or do you need to IPL z/OS to run it? If the
latter case, how does it keep your z/OS VWLC peak from reaching 32 MSU?
Is there some sort of VWLC exemption for running a z/OS "soaker"? Does
IBM allow you to exclude that LPAR's SMF records from your SCRT input?
