Last day, the petaflops limit is broken by the RoadRunner, the new supercomputer from IBM and owned by Los Alamos Nat Lab. The hardware is a nice mix with ~7,000 AMD Opterons and ~13,000 Cell Processors, connected by Infiniband. OS is RedHat with xCAT to control it. The cost was $133 millions USD.
Many of the applications include simulations in nuclear material aging and the sciences, financial, automotive and aerospace industries.
The RoadRunner will be soon the #1 in top500.
I want one of this!
