High Performance Computing Clusters
Stony Brook University researchers may access the services provided by the following two HPC clusters:
LI-red
LI-red is a computational cluster using top-of-the-line components from Cray, IBM, Intel, Mellanox and other technology partners. It is intended for members of the campus community, as well as industrial partners, and is located in the Institute for Advanced Computational Science's (IACS) server room.
SeaWulf
SeaWulf is a computational cluster using top of the line components from Penguin, DDN, Intel, Nvidia, Mellanox and numerous other technology partners. It is intended for members of the campus community, as well as industrial partners, and is located in the Computing Center.
New User Warnings
- If you have never used a high performance computing cluster, or are not familiar with SeaWulf, YOU WILL WANT to read and follow the instructions in the FAQ below (start with the Getting Started Guide!). It is a common practice by new users to ignore this FAQ and simply try to run jobs without understanding what they are doing. Such carelessness can and WILL easily impact the many users who are currently running critical jobs on the cluster. If your actions compromise the health of SeaWulf, your account will be LOCKED so please make sure you thoroughly read the guides below before you embark on running jobs.
- Do NOT use the login nodes for computationally intensive work of any kind. This includes compiling software. If everyone runs CPU- or RAM-intensive processes on either login node, it will crash and prevent all other SeaWulf users from being able to login to the cluster. If you need to test or compile your code, please request an interactive job instead of testing it on the login nodes!
- Do NOT use your home directory (/gpfs/home/NETID) to store large files as you may quickly exceed the directory’s storage limit (20 GB). It is best to place large or temporary files in your scratch directory (/gpfs/scratch/NETID), though please keep in mind that files and directories in scratch are automatically removed after 30 days. If your research group needs a persistent directory with a larger storage limit, consider requesting a shared project space.
- Never submit a large number of jobs (greater than 5) without first running a small test case to make sure your code works as expected. Start slow and then ramp up with jobs once you are familiar with how things work.
- SeaWulf is managed by a small number of System Administrators and students. If you encounter an issue or have problems running your job, please make sure you read through the FAQ items below before submitting a ticket to HPC Support.

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 14th 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.
- April 12, 2023
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.
- March 17, 2023
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.
- March 16, 2023
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.

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.
