Today in Cleantech

MIT’s Anant Agarwal is featured prominently in the recent article from Wired about low power processors. Agarwal is obsessed with building processors with lots of cores, and is putting out a 100 core processor via the company he launched, Tilera. Agarwal is open about the fact that 32-bit chips are “a nonstarter for the cloud,” a refreshingly honest perspective from the low power processor guys. It’s easy for him to say; Tilera released 64-bit chips last June. We’re still waiting on 64-bit ARM chips and HP’s ARM powered servers will be 32-bit, limiting their market. There are a number of roadblocks to low power server adoption, ranging from increased up front capital expense for the same amount of processing power and the need to recompile code to non x86 architecture. But clearly it isn’t stopping companies like Calxeda and Tilera from chipping away at objections to their chips.
