Doe to Field Pre-Exascale Supercomputers Within Four Years
In late 2016 or early 2017, Oak Ridge National Laboratory (ORNL), Argonne National Laboratory (ANL), and Lawrence Livermore National Laboratory (LLNL) aim to deploy their first 100-plus petaflop systems, which will serve as precursors to an exascale machine farther in the future.
The partnership between ORNL, ANL and LLNL, known as Collaboration Oak Ridge Argonne Livermore (CORAL), to secure the pre-exascale machines is similar to the approach of NERSC, Los Alamos, and Sandia National Labs to acquire their next round of supercomputers, known as NERSC-8 and Trinity. The CORAL supercomputers are initially specified at 100 to 300 petaflops, along with 5 to 10 petabytes of memory and 70 to 150 petabytes of storage. "The expectation is that the proposed 2016-2017 system will be roughly an order of magnitude less in time-to-solution than today's systems at our facilities," according to CORAL's Request for Information.
The CORAL lab proposals will have two distinct solutions. One of them will be delivered as separate systems to both ORNL and ANL, while LLNL will choose one of two solutions for its own use. Part of the CORAL effort will be to fund non-recurring engineering costs associated with the pre-exascale computers.
