Nice article, Was looking at some supercomuters myself not too long ago.. Then I figured out these things were pretty expensive and started building them myself..

This is a great advance in technology. The Cray XT5 delivers 1.75 Pflops, but is dwarfed by the Tianhe-1A's 4.669 petaflops when all its graphics processing units are operational.

Also to do the job, the Cray needed 224.000 processors This new Tianhe-1A needs "only" 21.500 which is great even if you are never going to carry your supercomputer around from time to time anyway..
