Energy Efficiency

IBM Building Energy-Efficient 20 Petaflop Computer

I have to admit, this news makes me drool a little bit. The US government agreed today to buy two supercomputers from IBM— including one that will scale to 20 petaflops. That’s 10 times the performance of today’s most powerful systems. The Sequoia system will be 15 times faster than BlueGene/P, but will have the same carbon footprint and only a small increase in power consumption.

You may recall that Argonne National Laboratory’s BlueGene/P, which makes 350 million calculations a second per watt, is the second most energy-efficient supercomputer in the world.

The Sequoia system will use 45nm processors with up to 16 cores per chip, and will have 1.6 petabytes of memory feeding its 1.6 million cores. IBM and DOE engineers will begin work on Sequoia in 2011, with an expected completion date sometime in 2012.

Former Tesla Battery Expert Leading Lyten Into New Lithium-Sulfur Battery Era — Podcast:

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
