Uh, you can look at the top500 list at the site. It's not like it's secret.
The highest ranking pseries is #3. Highest xseries is #53. There's _lots_ of both pseries and xseries on the list.
As for AS400 and mainframes, I'm quite sure you won't find em. They might be excellent in terms of RAS, but in terms of flops/$ they suck. Or any other relevant price/performance metric for HPC for that matter.
There's a couple of windows clusters. Mainly at the Cornell Theory center, which has some "partnership" with MS.
As for *BSD, I don't think you'll find them either. In this space, they don't really do anything that Linux doesn't do better.
There's a couple of OSX clusters. #16 and #20 for starters.
