Computing

The high-performance computing resources at CCV equip the Brown research community to undertake complex numerical simulation, modeling, and data analysis.

Oscar is our primary research computing cluster with several hundred multi-core nodes sharing a high-performance interconnect and file system. Applications can be run interactively or scheduled as batch jobs.

Several large memory nodes provide substantially more memory than is available on typical workstations and laptops.

A large collection of software is available on CCV systems, including:

  • python, perl, R, Matlab, Mathematica, Maple
  • optimized math and science libraries
  • domain-specific applications

We can help acquire and install most applications upon request.
