Hessian Minister of Economics visits Green IT Cube
On Wednesday, 24 February 2016, the Hessian Minister of Economics, Energy, Transport and Regional Development, Tarek Al-Wazir, visited the high-performance computing centre Green IT Cube at FAIR and GSI in the context of his excursion "Tour Digitalization in Hesse 2016". He was accompanied by Karin Wolff, who is a member of the Landtag of Hesse elected by the constituency Darmstadt Stadt II. Following up on the welcome by Jörg Blaurock, Technical Managing Director of FAIR and GSI, and professor Volker Lindenstruth, head of the GSI research area "Scientific IT", a guided tour of the Green IT Cube took place. It involved the galleries with computing racks as well as the balcony with view onto the not yet equipped steel framework and the utility buildings containing pumps and heat exchangers.
The Green IT Cube is an especially energy-efficient, space-saving and cost-effective high-performance computing centre. Instead of air, the Green IT Cube cools its computers with water. This means the energy used for cooling is only seven per-cent of the electrical power used for computing. Conventional computing centres with air cooling use 30 to 100 per-cent. The Green IT Cube will host 300,000 processing units. Scientists use it to perform simulations, to develop detectors for FAIR and to analyse measurements obtained from experiments in the accelerator facilities of GSI and, in future, FAIR.
Al-Wazir commented on the visit on Twitter: "One of the three (because of water cooling) most energy efficient computers in the world. Where? At GSI in Darmstadt of course" and documented his tour with pictures on Facebook and Twitter (in German).
