The HPC team has concluded initial evaluation of the Meltdown and Spectre processor vulnerabilities. All HPC systems are vulnerable, as are the vast majority of computing devices.
UPDATE: 12/23/2017 8:45AM System is back in service, we will continue to monitor. We apologize for the issues. Have a pleasant holidays-- HPC Team
On January 2, 2018 we will be setting the default process mapping for the system OpenMPI installations on Argon to "map by socket". This is being done to improve the process distribution of jobs in the absence of any specific process mapping given at job submission time.
Update: December 12, 2017 - 7:49 PM - The argon login nodes are back up.
Sorry about the inconvenience.
The Argon login nodes are currently down with a network issue.
The next scheduled maintenance window for the HPC systems is November 30, 2017 8AM - December 1, 2017 8AM.
During this time the Neon and Argon systems will be offline for maintenance. All jobs running at the beginning of the maintenance will be killed.
