A reminder that the Halstead cluster will be decommissioned in a little over a week, soon after the Thanksgiving holiday. Please start moving data to Fortress or other locations now to ensure you have time to save everything you need.

Link to original posting ORIGINAL:

The Halstead cluster has reached the end of its life cycle and will be retired on Thursday, December 1, 2022. Researchers who purchased access to Halstead should start archiving any data they may have there to the Fortress Archive now, or move it to other clusters or Data Depot for any ongoing work. After Halstead stops processing jobs on Thursday, December 1, 2022, there will only be 12 more days to remove or save and data on Halstead. Instructions on how to transfer data to Fortress can be found in the Fortress User Guide - File Transfer Section, and you can contact with any questions.

After Tuesday, December 13, 2022, RCAC STAFF WILL NOT be able to retrieve any data left in the Halstead scratch filesystem.

Shares in our latest community cluster, Negishi, are available for purchase now. Negishi will have considerable advantages over Halstead in many respects -- Negishi nodes contain many more processing cores that can be scheduled for jobs, and Negishi will provide more ability to take advantage of standby scheduling. Each Negishi node contains 256 GB of RAM. In addition, Negishi has faster networking, and a faster and larger scratch filesystem to improve your processing efficiency.

Purchasers of Halstead may receive a small credit once Halstead salvage value has been assessed, but all nodes will be retired and salvaged due their age. Please contact us at if you have any questions.
