Berkeley Lab Researchers Analyze Performance, Potential of Cell Processor
Though it was designed as the heart of the upcoming Sony PlayStation3 game console, the STI Cell processor has created quite a stir in the computational science community, where the processor’s potential as a building block for high performance computers has been widely discussed and speculated upon. To evaluate Cell’s potential, computer scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory evaluated the processor’s performance in running several… Read More »
Evaluating Application Performance on Big Iron
Four years ago, a group of scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Princeton Plasma Physics Laboratory began to undertake what would become one of the most comprehensive performance evaluations of supercomputers. The project, led by Lenny Oliker at Berkeley Lab, has produced findings that not only illustrated the strengths and weaknesses of various high-performance computing architectures, but also pinpointed bottlenecks in scaling applications for petascale computing down the road.
