It is my understanding that IBM intends to integrate Cell Blade engine (e.g. playstation 3) technology into the z/Series ecosystem. This would seem to me to be the place where massively parallel high intensity cpu workload would live in the not so far flung future.

Ok, so reality check folks before y'all start drooling about jobs and can think you can run 47000 windows servers under VM. In Linux we learned that running compiled code "natively" on "z", megahertz is megahertz and a CPU intensive task would always run faster on Intel than on "z" (until we got z9 and z10). And that is "native" meaning the programs were compiled to run on z, and the operating system was compiled to run on z. So now, under CMS, this emulates intel. So megahertz is NOT megahertz. With emulating an architecture, one could easily imagine losing an order of magnitude. Thus a windows server that is running at 10% peak on a 4Ghz processor would consume a z10 IFL and want more. One does need to pay significant attention to the performance characteristics before thinking about something like this seriously. Sorry. Gary M. Dennis wrote: > Z/VOS is a CMS application.
