JUBL ( Jü Licher B lue Gene / L ) was a supercomputer in the Jülich Research Center . The computer, inaugurated on March 6, 2006, was used for complex simulations in astrophysics, biology, climate research or physics. JUBL was dismantled in May 2008.
With 16,384 processors (8192 nodes with two processors each) and a main memory of 4.1 terabytes (512 megabytes per node), the computer achieved a peak performance ( Rpeak ) of 45.87 TFLOPS . The LINPACK performance ( Rmax ) was 37.33 TFLOPS. JUBL entered the TOP500 list in June 2006 at number 8 and was at number 18 in the June 2007 edition.
The processors used were 32-bit PowerPCs 440d with a clock rate of 700 MHz.
Additional infrastructure was formed by a service and login node, each with eight Power5-1.6 GHz processors and 18 and 8 GB of main memory. SUSE Linux Enterprise Server (SLES 9) was used as the operating system .
A BlueGene / P type computer was set up as a successor at Forschungszentrum Jülich . This computer, known as JUGENE , already performed 167 TFLOPS in measurements in November 2007.
