Cray® XC™ Series ‘Edison’ Supercomputer Helps Model 3-D Map of Adolescent Universe

Using extremely faint light from galaxies 10.8 billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice of the adolescent universe — just 3 billion years after the Big Bang. The map shows a web of hydrogen gas that varies from low to high density at a time when the universe was made of a fraction of the dark matter we see today. It was created in part using the Cray® XC30™ supercomputer “Edison” at the National Energy Research Scientific Computing Center (NERSC) by a team that included researchers from Berkeley Lab’s Computational Cosmology Center (C3).

Cray XC30 ‘Edison’ Overview

  • • Cabinets: 30
  • • Peak Performance: 2.57 PF
  • • System Memory: 357 TB
  • • Compute Nodes: 5,576 12-core Intel® Xeon® “Ivy Bridge” processors (24 cores per node)
  • • Compute Cores:133,824
  • • Interconnect: Aries
  • • Storage: 7.56 PB
  • • I/O Bandwidth: 163 GB

Cray and NERSC share a long history, starting with a Cray-1 in 1978. Its current Cray systems are the Cray® XE6™ “Hopper” system and Cray® XC30™ “Edison” supercomputer. In 2016, Cray will deliver “Cori” — a nextgeneration Cray® XC™ system that is expected to deliver 10 times the sustained computing capability of the Hopper supercomputer.
