Blue Gene is a computer architecture project designed to produce several next-generation supercomputers, designed to reach operating speeds in the petaflops range, and currently reaching sustained speeds over 360 teraflops.
It is a cooperative project among IBM (particularly the Thomas J.
Watson Research Center), the Lawrence Livermore National Laboratory, the United States Department of Energy (which is partially funding the project), and academia.
There are four Blue Gene projects in development: BlueGene/L, BlueGene/C, BlueGene/P, and BlueGene/Q.
On June 26, 2007, IBM unveiled Blue Gene/P, the second generation of the Blue Gene supercomputer.
Designed to run continuously at one petaflops, it can be configured to reach speeds in excess of three petaflops.
Furthermore, it is at least seven times more energy efficient than any other supercomputer, accomplished by using many small, low-power chips connected through five specialized networks.
