The delivery date for the U.S.'s first exascale supercomputing system, Aurora, has been extended from 2018 to 2021, while its target capability has been enlarged from 180 petaflops to 1 exaflop, according to announcements at Tuesday's Advanced Scientific Computing Advisory Committee meeting.
Despite this promise, the Collaboration of Oak Ridge, Argonne, and Lawrence Livermore (CORAL) initiative to build two distinct pre-exascale architectures has not met its goal.
Sources say several people at the U.S. Department of Energy (DoE) are disappointed with the Intel/Cray partnership contracted to deliver Aurora, because of its inability to fulfill its objective of providing a 180-200 petaflops system by 2018.
The scientific/research community sees the non-delivery of Aurora as significantly disruptive to them, especially because the supercomputer was wanted by both the DoE and Argonne National Laboratory.
However, two other CORAL projects at the Oak Ridge and Lawrence Livermore national laboratories remain on track.
