Researchers with the Lawrence Berkeley National Laboratory and Cray squeezed more I/O from the NERSC Cray XE6 “Hopper” supercomputer than ever before in a plasma physics simulation involving more than a trillion particles. The work paved the way for even bigger, exascale HDF5 workloads in the future, and yielded a scientific discovery as a bonus.
Hooper, the Opteron-powered Cray system at NERSC has been tasked with helping scientists on the Planck space telescope project filter ancient light against sensor signals to help astronomers understand the….
NERSC director Kathy Yelick shares insights on programming petascale systems like the Hopper system.
The Weekly Top Five features the five biggest HPC stories of the week, condensed for your reading pleasure. This week, we cover NERSC’s acceptance of its first petascale supercomputer, the potential for magnets to revolutionize computing; NCSA’s private sector supercomputer; the official debut of Australia’s MASSIVE supercomputer; and PRACE’s biggest supercomputing allocation yet.
