OSC project filesystem resuming normal operations
The issue with the Project file system that causes deletes of file system snapshots to fail has now been resolved. OSC Project file system has resumed normal operations. We are still working with our storage vendors to identify how to perform remaining maintenance work. We will update you as much advance notice as possible if it causes any disruption to users.
Huge memory nodes partial scheduling
Beginning on Tuesday, March 10th users are able to run jobs using less than a full huge memory node on both the Owens and Pitzer clusters.
Please consider your request more carefully when you plan to use a huge memory node, and specify the resources based on what you will use. Please check our documentation for more detailed guidance:
