The San Diego Supercomputer Center (SDSC) at the University of California, San Diego has transitioned into the early operations stages of its new Comet supercomputer. When it is fully functioning, the new cluster will have an overall peak performance approaching two petaflops.

Comet has been designed as a solution for the "long tail" of science, which refers to the significant amount of research that is computationally-based, but modest-sized. Together, these projects represent a great amount of research and potential scientific impact. Much of this research is being conducted in disciplines that are new to high performance computing such as economics, genomics and social sciences.

The Comet cluster includes:

  • An Intel Xeon® Processor E5-2600 v3 family, with two processors per node, and 12 cores per processor running at 2.5GHz.
  • 128 gigabytes (GB) of traditional DRAM and 320 GB of local flash memory on each compute node.
  • 27 racks of 72 nodes each (1,728 cores) with a full bisection InfiniBand FDR interconnect from Mellanox, and a 4:1 over-subscription across the racks.
  •  A total of 1,944 nodes or 46,656 cores
