Polaris nodes with Slingshot 10 (60% of the system) are available for use. However, we are still working on making the Slingshot 11 nodes available. The upgrade will continue on November 6 and November 13. For details on how this effects queues and job submissions, see: https://www.alcf.anl.gov/polaris-slingshot11-upgrade.
