New Petaflop computer planned for 2008

The Energy Department’s Oak Ridge National Laboratory and Cray announced a $200 million deal in June to make a petaflop computer in 2008. The computer code, dubbed Qbox, will help researchers run science simulations deemed essential to national security. The supercomputer, which Cray nicknamed Baker, will use optimized Advanced Micro Devices dual-core Opteron processors.

The current fastest computer is the japanese MD Grape 3 which is already at a petaflop.
The fastest computer that can run standard benchmark code is the Blue Gene computer.
