In the late 1980s I was involved with a customer to look at (then) DFHSM to figure out how to control the number of parallel tasks on each machine (MVS/ESA image). This was for (then) 24-bit virtual storage management purposes. I vaguely recall we could decide which system had how many of each type of task - obviously long before Parallel Sysplex.
I wonder if such an approach could control WHERE the CPU is consumed, as much as how much. Probably doesn't help the OP, though.

I teamed up with Frank Kyne of Watson & Walker to write an article on this topic in their newsletter. I'm also more than happy to give a WebEx on this topic with this client, and any other who is interested. It's a popular presentation from IBM TechU and SHARE. One of the topics is to reduce the MAX tasking level to reduce peak MIPS during HSM windows. Just send me an email.
