IBM to build fast computer
Interesting that they will use GNU/Linux in the massively parallel Blue Gene/L but not the pending ASCI Purple which will utilize AIX/5...Obviously they realize GNU/Linux is going to scale better.

The second supercomputer, a research machine called Blue Gene/L, will employ advanced IBM semiconductor and system technologies based on new architectures being developed in the ongoing partnership between IBM and the DOE for the government’s ASCI Program. When completed, Blue Gene/L will have a theoretical peak performance of up to 367 teraflops with 130,000 processors running GNU/Linux. It will have the capability to process data at a rate of one terabit per second, equivalent to the data transmitted by ten thousand weather satellites. The supercomputer will be used by the three NNSA laboratories (Los Alamos, Sandia and Lawrence Livermore) and the ASCI University Alliance collaborators as well as other DOE laboratories in the future.
