Greetings.
As a newbie to the mainframe environment (my background is mostly linux), I have grown
enthusiastic about this superior hardware I knew very little about. Nevertheless, I
have always found it a shame that number crunching workloads are not a good match to
the mainframe.

So what if we could patch a zLinux image kernel and then made it one of the node

CPU intensive jobs from the linux/mainframe to cheaper external engines.
The part of offloading cycles to a cheaper platform, is that we would
be offloading to a more expensive platform (intel). Not that the Intel
box isn't cheap, but the economic reasons for server consolidations is
to get away from these cheap boxes.

Actually, the IBM zSeries do make use of IA32 processors...the HMC is PC
based. And let's not overlook those two IBM ThinkPads embedded inside each
zSeries box, acting as the support element (SE) processors.
However, none of those IA32 systems are in direct line of executing 390
