Support

The Resnick High Performance Computing Center provides operational, technical, and research computing support for Caltech researchers using the central HPC infrastructure.

Support ranges from basic onboarding and account assistance to performance optimization, software environments, GPU workflows, large-scale parallel computing, and long-term collaboration on computational research projects.

We aim to make advanced computing resources approachable, reliable, and productive for research groups across the Institute.

Getting Help

The best way to reach us is through the HPC support email or the Caltech Help System

Tip

When submitting a request, include:

• your username and associated research group

• job IDs, error messages, or command output

• relevant submission script locations or software versions

• steps needed to reproduce the issue

• whether the problem is new or previously failing

The more context we have, the faster we can usually identify the root cause.
