It's the "Most powerful Unix machine in the world" native, and it also runs under VM (though not as fast). Amdahl's hardware is faster than IBM's, so it beats an Unix IBM has (yet) to deliver. Sorry, i don't think we've written any papers on the subject of running under VM. There's really not alot to say, aside from paying attention to all the idiosyncracies of whatever VM you're running under, in order to get decent performance. It's particularly hard to get decent performance using virtual memory as a "Virtual Operating System". -- George Bush snorts Contra coke. craig@uts.amdahl.com {uunet,sun,decwrl}!amdahl!craig [views above shouldn't be viewed as Amdahl views, or as views from Amdahl, or as Amdahl views views, or as views by Mr. Amdahl, or as views from his house]
