Wulver will be out of service on Tuesday, August 12th, for OS and SLURM updates.
This spring semester, we are offering drop-in office hours every Monday and Wednesday from 2:00 to 4:00 p.m. Stop by to meet with our student consultants and ask any questions you have about using HPC resources. Whether you’re just getting started or need help with a specific issue, feel free to bring your laptop to walk us through any problems you're facing. There's no need to create a ticket in advance; if follow-up is needed, the student consultants will open a ticket on your behalf, and you'll receive further instructions.

Wulver Monthly Maintenance
Beginning Feb 1, 2024, ARCS HPC will be instituting a monthly maintenance downtime on all HPC systems on the second Tuesday from 9AM - 9PM. Wulver and the associated GPFS storage will be taken out of service for maintenance, repairs, patches and upgrades. During the maintenance downtime, logins will be disabled, users will not have access to their stored data in /project, /home and /scratch. All jobs that do not end before 9AM will be held by the scheduler until the downtime is complete and the systems are returned to service.
We anticipate maintenance to be completed by the scheduled time. However, occasionally the maintenance may be completed earlier than scheduled or could be extended to the following days. A notification will be sent to the user mailing list when the systems are returned to service or the maintenance window is extended. Additionally, users will encounter the cluster service information upon logging in to Wulver during maintenance. Please pay attention to the Message of the Day when logging in, as it will serve as a reminder for upcoming downtimes or other crucial cluster-related information. Users should take into account the maintenance window when scheduling jobs and developing plans to meet various deadlines. Please do not contact the help desk, HPC staff or open SNOW tickets for access to the cluster or data during the maintenance downtime.
Lochness is Back Online!
Lochness is mostly back up after being moved to a new facility. The move required complete disassembly and reassembly of the entire cluster. There are 8 nodes down as they were damaged in the move, repairs forthcoming. Infiniband network issues affect 50 nodes, these are in "drain" state. Currently 120 nodes are fully functional. You can use sinfo to see the exact states of nodes accessible to you. Please email hpc@njit.edu for assistance.
GPFS Fileset Changes
Wulver will be out of service Wed Oct 18th between 9:00 am-11:00 am for updates and configuration changes. The maintence will be conducted to fix the stale file handle error on /scratch while accessing files from login node.
Dear Lochness Users,
We hope this message finds you well. We want to inform you of an upcoming significant event regarding our HPC (High-Performance Computing) cluster, lochness.njit.edu. The GITC datacenter is scheduled for demolition on November 1, 2023. In order to maintain the operation of our computing infrastructure, we will be relocating the cluster to the Databank colocation facility in Piscataway.
The scheduled shutdown of the lochness.njit.edu cluster will take place on October 6th, 2023. We have estimated that the relocation process will require no longer than five days to complete. During this time, the cluster will not be accessible. We understand the importance of uninterrupted access to computational resources, and we will make every effort to minimize downtime.
Rest assured that we are committed to maintaining cluster availability for your research and academic needs. The lochness.njit.edu cluster will remain operational until the end of the current semester. This means that you will have access to its computing power throughout your ongoing projects and coursework.
Our team is actively working on the migration process to ensure a smooth transition for all users. We plan to migrate all users to the new cluster, wulver.njit.edu, well before the end of the semester. Detailed instructions and support will be provided to facilitate this transition, and we will keep you updated on the migration progress.
We understand that this relocation may raise questions or concerns, and we are here to address them. Please feel free to reach out to hpc@njit.edu you have any specific inquiries or require further information.
We appreciate your understanding and cooperation during this transitional period. The relocation of our HPC cluster is aimed at providing you with an improved and more reliable computing environment.
Thank you for your ongoing support and contributions to our research community.
