Announcements

We have just been notified of scheduled electrical maintenance at the Campus Data Center on Tuesday August 22^nd. During these necessary electrical upgrades the 28-core and GPU (K80) queues will be off-line and jobs running on those queues will be terminated, starting at 9:00 AM on Tuesday the 22^nd. The maintenance is expected to be completed by the end of business on the 22^nd.

No other queues will be affected, and the login nodes will remain accessible during this maintenance period.

We thank you for your patience while these necessary upgrades are completed.

In preparation for a new expansion to SeaWulf (announcement to follow), we will be performing maintenance on the 96-core, 40-core, and A100-GPU queues, as well as the milan.seawulf.stonybrook.edu login nodes, starting at 10:00 AM on Wednesday June 14^th and concluding by the end of business the same day.

During this maintenance window, the 28-core and GPU queues, as well as the login.seawulf.stonybrook.edu login nodes will continue to be available.

We thank you for your patience while we perform these necessary preparations.

In order to allow the university to perform electrical maintenance on the circuits for the 24-core queues and the login node 'Login2', they will be offline starting Sunday evening April 16th concluding Tuesday April 18th by the end of the day. No other queues will be affected, and the login node 'Login1' will remain accessible during this maintenance period.

We thank you for your patience while these necessary upgrades are implemented.

We have just been notified by the manufacturer of a critical firmware update that needs to be applied to SeaWulf to ensure we can continue to provide a robust computational environment. Out of an abundance of caution, we are taking an emergency maintenance window, scheduled for ~3 hours from now at 3:30 PM today. This window is expected to last for ~24 hours.

During this maintenance window, all Seawulf login nodes and queues, as well as the storage will NOT be available.

We apologize for this unforeseen development, and thank you for your patience while we apply these critical firmware updates.

In order to allow the university to perform electrical maintenance on the campus data center, the 28-core and Tesla K80 gpu queues will be going offline starting at end-of-business on March 21st. These queues will come back online after the maintenance is concluded by the end of business on March 22nd. No other queues will be affected, and the login nodes will remain accessible during this maintenance period.

We thank you for your patience while these necessary upgrades are implemented.

In order to perform the 2nd phase of updates on the SeaWulf storage arrays, upgrade the networking and perform electrical maintenance on the infrastructure, the SeaWulf cluster will be going off-line starting 9:00 AM on Wednesday February 15th. The maintenance is expected to be completed by the end of business on Thursday February 16th. During this maintenance window, all login nodes, compute nodes as well as the storage array will NOT be accessible.

We thank you for your patience while we perform these necessary updates.

In order to perform updates on the SeaWulf storage arrays, the SeaWulf cluster will be going off-line starting at 9:00 AM Tuesday December 6th . The maintenance is expected to be completed by the end of business on Wednesday December 7th. During this maintenance window, all login nodes, compute nodes as well as the storage array will NOT be accessible.

The second phase of this two part maintenance is tentatively scheduled for January 4th and 5th.

We thank you for your patience while we perform these necessary updates.

Starting at 5:00 PM on Friday September 30th, the 40-core queues on the SeaWulf cluster will be going off-line for scheduled maintenance. All jobs, queued or running, on the 40-core queues at that time will need to be resubmitted at the end of the maintenance window, which is scheduled to conclude on Friday October 7th by the end of business.

The 24-core, 28-core and 96-core queues will be in operation throughout this time. Thank you for your patience while we perform these necessary maintenance operations.

The intel-stack module has been updated to provide compilers, MKL, and MPI from Intel oneAPI version 2022.2.

Older versions of the Intel modules are still available and can be loaded individually, but they are no longer part of the intel-stack module.
