retire Cori config

[cms21]

Per NERSC:

NERSC will retire the Cori supercomputer in one week, on Wednesday, May 31 at noon (Pacific time). Here is a detailed breakdown of what will happen on that date and after.
At 12:00 noon next Wednesday, May 31, Cori queues will be turned off. A reservation has been put in place to prevent any jobs from running over, but any errant jobs will be deleted at that time. All jobs in the queue will be deleted.
Cori login nodes and scratch file systems are planned to be available until 12:00 PST (noon) on June 7, 2023, to provide a final opportunity for users to retrieve their files off the Cori-specific scratch file system.
Please save your important files from the Cori scratch file system to HPSS, your CFS directory, or elsewhere at your earliest convenience. If you plan to back up many small files to HPSS, be sure to use the htar utility to concatenate those small files into a larger archive.
