QCL Computational Resources
High Performance Computing (HPC)
Local HPC and Compute Server Resources
(1) Local (on-premises) Compute Server: RStudio Server and JupyterHub
We have a dedicated server machine for RStudio and JupyterHub. Students taking a CMC course using R or Python, and participating in a QCL workshop may get access to the computational resources. To get access to the RStudio Server and/or JupyterHub, please contact [email protected] for your account activated. The RStudio Server and JupyterHub are equipped with 2 CPUs (32 cores) and 512 GB of memory. So, it will perform better than your laptop or personal computer (for sure!) for those who need large memory space.
(2) NVIDIA GPU Machine
A GPU (Graphic Processing Unit) machine is a high performance computer system equipped with one or more GPUs. QCL has an NVIDIA DGX system having four Tesla V100 GPUs. To use the NVIDIA DGX system, please contact us at [email protected] and provide your project details. The NVIDIA DGX is a shared resource and its availability depends on the number of projects we are hosting. (As of February 2025, we are hosting Data Science Capstone projects and a CGU Math Clinic project.)

| Network | Dual 10GBASE-T (RJ45) |
Remote HPC Resources
(1) Regional HPC Cluster Allocations through SoCal Research Computing and Data Alliance
The SoCal Research Computing & Data Alliance (led by USC), a collaboration of 12 academic institutions including all the Claremont Colleges, was awarded an NSF CC* grant and launched a high-performance computing (HPC) cluster, Laguna, which is managed by USC. The Laguna cluster is available for the CMC faculty for their computational and data-intensive research and teaching.
If you are interested in using the Laguna HPC Cluster:
- Sign up using this form.
- Send an email to [email protected], so we can assist you with onboarding.
Configuration of the Laguna HPC Cluster
- 1 Login Node
- 16 Compute Nodes: 128 cores/node, 365 GB/node
- 8 GPU Nodes: Dual Nvidia L40S/node, 735 GB/node
- Storage (hot): 100GB/user, 5TB/project (with 5TB increments per request per project)
(Note on storage: no cold storage (tape or slow disk storage) available. The Laguna system does not support the use or storage of sensitive data (e.g., HIPAA-, FERPA-, or CUI-regulated data).)
(2) National Supercomputing Allocations through NSF ACCESS (formerly XSEDE)
ACCESS is a collection of integrated advanced digital resources and services that provide easy access to the most advanced computational resources and scientific research support in the world. QCL has two Campus Champions who are trained to help local users utilize national supercomputing resources available through the NSF Access program. From various national supercomputing facilities, QCL has awarded a large number of computing hours for testing and developing scientific applications (see below).

The Service Unit (SU) is like a currency used to run an application on supercomputers. Supercomputer users are charged by SUs (hours of runtime on one core). For example, if an application ran on 100 cores for 10 hours, 1,000 SUs will be deducted from your account.
The Campus Champion allocations can be used to test computational research applications. To test out the supercomputers, please make an appointment with one of the CMC Campus Champions (email: [email protected]).
