JUGENE

JUGENE ( Jülich Blue Gene ) was a supercomputer from the Blue Gene / P at Forschungszentrum Jülich and successor of the operated there until 2008 JUBL. The computer belonged to the Institute Jülich Supercomputing Centre (JSC ) and the virtual Gauss Centre for Supercomputing.

With 294,912 clocked at 850 MHz Power PC 450 cores and 144 terabytes of main memory - each of the 73 728 nodes contained a quad-core processor and two gigabytes of RAM - 72 in cabinets provided the computer has a power output of 825.5 TFLOPS (Rmax ).

Was financed the purchase by the Research Center, the state of North Rhine -Westphalia, the German Federal Ministry of Education and Research and the Helmholtz Association. The head of the JSC Thomas Lippert emphasized " the special feature of our JUGENE is in comparison to other systems, very low power consumption with maximum computing power " - a Blue Gene / P system is intended to afford watts according to the manufacturer about 0.35 GFLOPS / almost twice be as efficient as the previous model at the same location used.

The official inauguration in the presence of the North Rhine-Westphalian Minister President Jürgen Rüttgers took place on 22 February 2008; also on this day went a few hours later, the civil but also even faster Ranger at the Texas Advanced Computing Center ( TACC ) at the University of Texas at Austin officially put into operation.

The former first version of JUGENE reached with 16 racks an official Linpack performance of 167.3 TFLOPS (Rmax ) and secured himself as the fastest of civilian computer # 2 on the TOP500 list of November 2007.

The upgrade to the last stage was inaugurated on 26 May 2009 and put to productive use from 1 July 2009. The mark of 1 petaflops ( Rpeak ) was breached for the first time in May 2009 - JUGENE is therefore referred to as the first European petaflop computer.

JUGENE 2012 has been switched off and from May 2012 replaced by the Blue Gene / Q system JUQUEEN that occupies the 8th of June 2012 in the 39th TOP500 list.
