JuQUEEN, Juelich, Germany

JuQueen is the newest system at the Forschungszentrum Juelich (FZJ) supercomputing center in Germany, whose JuGENE system previously held a spot in the top 10. The structure of the Blue Gene/Q is similar to that of the Blue Gene/P with increased performance metrics and on-board water cooling. The system consists of eight racks and will have a peak performance of 1.6 petaflops. It clocked in at 1.38 petaflops in the Linpack testing for the Top 500. One rack contains 32 node boards with 32 compute nodes each. A node consists of a processor comprising 16 IBM PowerPC A2 cores (1.6 GHz, 64 bits) for the execution of user applications; one additional core is used for the operating system. Each core can execute four processes/threads and has a quad floating point unit.
