The /work filesystem, which is mounted across all machines, is currently experiencing instability. Users may see slow or interrupted I/O during jobs. In particular, any users who are dependent on the /work filesystem for their conda settings are likely to be impacted. It is recommended to review your workflows, especially on the login nodes, to reduce dependence on /work temporarily. Admins are continuing to investigate the issue, and an update will be posted when the problem is resolved.

Dear TACC Community, Starting Tuesday, October 1st, we will be implementing a new policy regarding how short-duration jobs are charged on our systems. All jobs which start will be charged a minimum of 0.25 SUs per node regardless of actual runtime. This is equivalent to 15 minutes of runtime. This change be will applied to all TACC resources. We understand that large jobs will be the most affected and encourage users to do thorough testing at smaller node counts before increasing the size of their jobs in order to reduce the impact of this change. Thank you for your cooperation and understanding. If you have any questions about this change, please submit a ticket: https://tacc.utexas.edu/portal/tickets
