JUGENE

JUGENE (Jülich Blue Gene) was a <a href="/facts/Supercomputer/HT9NwGAN">supercomputer</a> built by <a href="/facts/IBM/QszA7nwd">IBM</a> for <a href="/facts/Forschungszentrum_J%C3%BClich/72Kc5S0N">Forschungszentrum Jülich</a> in Germany. It was based on the <a href="/facts/Blue_Gene/y4EvbyS4">Blue Gene/P</a> and succeeded the <a href="/facts/J%C3%BClich_Research_Centre/72Kc5S0N">JUBL</a> based on an earlier design. It was at the introduction the second fastest computer in the world, and the month before its decommissioning in July 2012 it was still at the 25th position in the <a href="/facts/TOP500/rz8zbyss">TOP500</a> list. The computer was owned by the "Jülich Supercomputing Centre" (JSC) and the <a href="/facts/Gauss_Centre_for_Supercomputing/WCU1X8Ch">Gauss Centre for Supercomputing</a>.
With 65,536 <a href="/facts/PowerPC_400/X6zS1Rgu">PowerPC 450</a> cores, clocked at 850 MHz and housed in 16 cabinets the computer reaches a peak processing power of 222.8 <a href="/facts/FLOPS/6zYlH68F">TFLOPS</a> (Rpeak). With an official <a href="/facts/Linpack/2VtBJ2va">Linpack</a> rating of 167.3 TFLOPS (Rmax) JUGENE took second place overall and is the fastest civil/commercially used computer in the <a href="/facts/TOP500/rz8zbyss">TOP500</a> list of November 2007.
The computer was financed by Forschungszentrum Jülich, the State of <a href="/facts/North_Rhine-Westphalia/0QmCWxjo">North Rhine-Westphalia</a>, the Federal Ministry for Research and Education as well as the <a href="/facts/Helmholtz_Association_of_German_Research_Centres/ad3cxFIh">Helmholtz Association of German Research Centres</a>. The head of the JSC, Thomas Lippert, said that "The unique thing about our JUGENE is its extremely low power consumption compared to other systems even at maximum computing power". A Blue Gene/P-System should reach about 0.35 GFLOPS/<a href="/facts/Watt/VK8oqRrm">Watt</a> and is therefore an order of magnitude more effective than a common <a href="/facts/X86/Kypq5fgu">x86</a> based supercomputer for a similar task.
In February 2009 it was announced that JUGENE would be upgraded to reach petaflops performance in June 2009, making it the first <a href="/facts/Petascale/HbIWaQ0L">petascale</a> supercomputer in Europe.
On May 26, 2009, the newly configured JUGENE was unveiled. It includes 294,912 processor cores, 144 <a href="/facts/Terabyte/BNHUp9Qq">terabyte</a> memory, 6 <a href="/facts/Petabyte/BNHUp9Qq">petabyte</a> storage in 72 racks. With a peak performance of about one <a href="/facts/FLOPS/6zYlH68F">PetaFLOPS</a>, it was at the time the third fastest supercomputer in the world, ranking behind <a href="/facts/IBM_Roadrunner/tXDaFkQM">IBM Roadrunner</a> and <a href="/facts/National_Center_for_Computational_Sciences/CE3w1ekX">Jaguar</a>. The new configuration also incorporates a new water cooling system that will reduce the cooling cost substantially.
The two front nodes of JUGENE are operated with <a href="/facts/SUSE_Linux_Enterprise_Server/Fqf31h9R">SUSE Linux Enterprise Server</a> 10.
JUGENE was decommissioned on 31 July 2012 and replaced by the Blue Gene/Q system <a href="/facts/JUQUEEN/72Kc5S0N">JUQUEEN</a>.
