Parasol Resources Overview

Computational Resources

Computing in the Parasol laboratory is primarily based on the Linux operating system, specifically the community-oriented CentOS, and Open Source software, on both workstation and server platforms. The network services provide version control, project tracking, identity and configuration management, web publishing and database back ends (among other functions). Two ROCKS-based clusters are implemented for project testing and benchmarking.

We also support undergraduate and graduate instruction for our faculty members.


Cray XE6m Supercomputer at Parasol CRAY XE6m Supercomputer
• 24 compute nodes, with the following characteristics:
  • 12 regular nodes each with two 16 core 64-bit AMD© 'Interlagos' 2.1 GHz CPUs, for a total of 384 cores.
  • 12 accelerated nodes, each with one 16 core 64-bit AMD© 'Interlagos' 2.1 GHz CPU, Kepler© K20 GPU, for a total of 192 cores.
  • Note: Grand total is 576 cores.
  • Additionally, each Kepler K20 has a total of 2496 GPU cores, approaching a peak double precision performance of 1.17 TFLOPS, or 3.52 TFLOPS in single precision. The total GPU core count is 29,952.
