A new milestone in high performance computing was reached late Tuesday evening (1/22/13) when Stanford researcher and Cascade consultant Dr. Joe Nichols ran the CharLES solver on more than 1 million processor cores. This breakthrough happened during "Early Science" testing of the newly installed Sequoia supercomputer at the Lawrence Livermore National Laboratories (LLNL). The Sequoia IBM Bluegene/Q system is currently ranked No. 2 on the list of the world's most powerful supercomputers boasting 1,572,864 compute cores and 1.6 petabytes of memory connected together with a high-speed five-dimensional torus interconnect. A CFD simulation tasks all parts of a supercomputer ...

Among them, the Intrepid system at Argonne is one of the two leadership computing facilities supported by the U.S. Department of Energy (DOE), and it currently stands at number 23 in the latest Top500 world ranking (November 2011). Intrepid consists of 40 Blue Gene/P racks of 4096 cores each for a total of 163840 cores. A visual snapshot of the daily activity on Intrepid can be seen below, where each of the smallest squares is made up of 128 cores, every larger block represents ...
