About

Mission

The Resnick High Performance Computing Center provides advanced computing infrastructure and technical expertise for sponsored research at Caltech. The Center:

  • Evaluates, acquires, and operates HPC infrastructure — including compute nodes, GPUs, storage systems, and high-speed interconnects — together with the software environment required to support research computing at scale.

  • Provides technical guidance through documentation, ticket-based support, and one-on-one consultations for code porting, scaling, debugging, and workflow optimization.

  • Evaluates emerging computational technologies — including accelerators, filesystems, schedulers, and AI infrastructure — to ensure new capabilities are ready as campus research needs evolve.

  • Collaborates with peer computing centers and technology vendors to share expertise and advance capabilities that benefit the broader research computing community.

Research community

The Center supports researchers across all Caltech divisions, including faculty, postdoctoral scholars, graduate and undergraduate students, and staff scientists.

Research workloads span astronomy and astrophysics, structural biology and cryo-EM, AI/ML training, computational chemistry, geophysics, computational engineering, and many other data-intensive scientific disciplines, all supported by a shared high-performance computing infrastructure.
