NERSCPowering Scientific Discovery Since 1974

Edison's last day is May 13, 2019

NERSC Edison opened for production use on January 14, 2014, and after exactly 64 months of providing a supercomputing capability to DOE projects, will retire on May 13, 2019.

Edison was serial number 1 of the Cray XC line and the first to use the Aries network with Dragonfly topology, also used in Cori. Edison's retirement will make room for the installation of Perlmutter, NERSC's next supercomputer.

In preparation for Edison's retirement, we recommend that all users:

1. Migrate your Edison-based workflows to Cori. The architecture Cori's Haswell nodes is most similar to that of Edison, but most optimizations you make to run your workflow on Cori KNL will be also beneficial on Perlmutter, and with about four times as many KNL as Haswell nodes, the queues will be shorter.

2. Make sure that all important data on Edison $SCRATCH and /scratch3 is backed up to HPSS or elsewhere. The Edison scratch filesystems are part of Edison and will retire along with the rest of Edison.
