Note
Software configurations on NU HPC facilities are updated on a continuous basis. The limits on job execution and maximum storage allocations are subject to change based on decisions made by the NU HPC Committee and actual system utilization.
Acceptable Use
The HPC system is a unique resource for NU researchers and the community. It has special characteristics, such as a large amount of RAM and the capability for massive parallelism. Due to its uniqueness and expense, its use is supervised by the HPC team to ensure fair and efficient utilization.
Storage quotas
Current default storage quota for users’ home directories is set to 100 GB. If any individual user requires more storage for his/her work, it can be allocated through a special request to the HPC admins. For particularly large, multi-terabyte storage needs Shabyt has an HDD array with the total capacity of 120 TB.
Data integrity and backup
Please be advised that users take full responsibility for the integrity and safety of their data stored on NU HPC facilities. While our clusters feature enterprise level hardware, failures are still a possibility. We do backup data in user home directories automatically several times a week (note that this applies only to your home directory in /shared/home, not to the group storage allocations in /zdisk). However, if a major hardware failure takes place, even if your data is eventually restored, you may not have access to it for a prolonged period of time while the system is being repaired. In some unfortunate situations it might take many days or even weeks to get everything back. Moreover, no system or storage solution is 100% reliable. Therefore we highly recommend that you backup most important and precious data on your personal computer from time to time.
Queues and the number of jobs
Currently, Shabyt has two partitions for user jobs. While at this time, when the system is still being configured and fine-tuned, there is no hardcoded limit on the number of jobs by any individual user, it will likely change in the near future.
Acknowledgment
If the computational resources provided by NU HPC facilities were an important asset in your work resulting in a publication, we will greatly appreciate your acknowledgment.
