IBM has begun building the chips that will be used in the first Blue Gene, a machine dubbed Blue Gene/L that will run Linux and have more than 65,000 computing nodes, said Bill Pulleyblank, director of IBM's Deep Computing Institute and the executive overseeing the project. Each node has a small chip with an unusually large number of functions crammed onto the single slice of silicon: two processors, four accompanying mathematical engines, 4MB of memory and communication systems for five separate networks.
