| The prestigious Gordon Bell Prizes were awarded last November at the SC06 conference in Tampa, FL. Dr. Francois Gygi led a winning team, which also includes Dr. Bronis de Supinski. Both researchers are also members of SciDAC project teams. |

| Titled “Large-Scale Structure Calculations of High-Z Metals on the BlueGene/L Platform,” the entry won in the “peak performance” category, judged on sustained floating point operations per second. Such research on heavy metals is of interest to scientists with the National Nuclear Security Administration’s (NNSA) Stockpile Stewardship Program. | ||||
| Dr. Gygi’s team used the first principles molecular dynamics (FPMD) code called Qbox to achieve simulations of unprecedented scale and detail. A sustained peak performance of 207.3 TFlop/s was measured on 65,536 nodes, corresponding to 56.5% of the theoretical full machine peak using all 128,000 CPUs. |
