Operators of the supercomputing center at Argonne National Laboratory used innovations in both computer architecture and cooling methods to achieve over $1 million in annual energy savings for its IBM Blue Gene/P supercomputer. Supercomputers typically consume multiple megawatts of electricity. At 557 teraflops, Argonne's Blue Gene/P is one of the fastest supercomputers in the world, but uses as little as one-third the power consumed by other supercomputers.
BOTTOM LINE: Going green can be a matter of degree, and was achieved here by tuning the design of this supercomuter facility rather than adopting expensive new technologies.
