A 2000-processor Intel Itanium 2 supercomputer at the U.S. Department of Energy's Pacific Northwest National Labs may have edged out Lawrence Livermore National Lab's Intel Xeon-based Multiprogrammatic Capability Cluster for the title of world's fastest Linux supercomputer.
The PNNL says that its supercomputer cluster takes the crown following completion of an upgrade this week. The lab has boosted the system's peak performance from 6.2 trillion floating point operations per second (T FLOPS) to 11.8T FLOPS.
The upgrade involved adding 1400 1-GHz Itanium 2 McKinley processors in the PNNL's William W. Wiley Environmental Molecular Sciences Laboratory supercomputer in Richland, Washington. The new processors run at 1.5 GHz and are based on Intel's follow-up to its McKinley design, which is called Madison.
