IBM liquid-cooled supercomputer heats building

An IBM supercomputer is doubling as a space heater via a technique that reduces energy use by 40 percent and dramatically lowers the overall carbon footprint.

Based at Swiss university ETH Zurich and dubbed Aquasar, the liquid-cooled supercomputer went live on Thursday and started analyzing fluid dynamics while simultaneously providing heat for the building. In a typical data center, about half of the energy is used for cooling.

Researchers at IBM and ETH Zurich will monitor the system, which consists of two IBM BladeCenter servers in one rack, able to compute six teraflops. They will be gathering data on energy performance but one of the main goals of the project is to show that liquid-cooled computers are possible, according to an IBM representative.
