I’m looking forward to reading more about Blue Gene/P (coming to Argonne!). Excerpt from the press release:

ARMONK, NY – 26 Jun 2007: IBM (NYSE: IBM) today announced Blue Gene/P, the second generation of the world’s most powerful supercomputer. Blue Gene/P nearly triples the performance of its predecessor, Blue Gene/L — currently the world’s fastest computer — while remaining the most energy-efficient and space-saving computing package ever built.

The IBM System Blue Gene/P Solution scales to operate continuously at speeds exceeding one “petaflop” — or one-quadrillion operations per second. The system is 100,000 times more powerful than a home PC and can process more operations in one second than the combined power of a stack of laptop computers nearly 1.5 miles high. The Blue Gene/P supercomputer can be configured to reach speeds in excess of three petaflops, a performance level that many thought unattainable only a few short years ago.
