Parasol Resources Overview

Computational Resources

Computing in the Parasol laboratory is primarily based on Unix-based operating systems such as Linux and Mac OS X, and Open Source software. Researchers have Fedora Linux and OS X workstations, supported by CentOS servers providing 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.
