ABSTRACT

With the IBM Blue Gene/P supercomputer JUGENE, inaugurated in May 2009 at the Julich Supercomputing Centre (JSC), the Forschungszentrum Julich has entered the era of petaflop supercomputer performance in Europe. The Julich Supercomputing Centre (JSC), as a part of the Institute for Advanced Simulation within the Forschungszentrum Julich, operates supercomputers of the highest performance class in Europe. When IBM Blue Gene technology became available in 2004/2005, Forschungszentrum Jülich recognized the potential of this architecture as a leadership-class system for capability computing applications. The lifetime of the largest Blue Gene/P in the world ended in mid 2012 after having been in operation for over three years and being superseded by an IBM Blue Gene/Q system. Blue Gene/P is an MPP type system with the design goal of achieving an optimal Performance/Watt ratio and extreme scalability. The JUGENE system in Julich consists of 72 Blue Gene/P racks, configured as 9 rows with 8 racks each, which sums up to 73,728 nodes.
