I am corresponding to update you on several aspects of our ISTeC High-Performance Computing (HPC) Initiatives:

  1. The HPC system to be purchased under the joint NSF $3 million MRI award to CSU and UC-Boulder is in the purchasing process, and is scheduled to be available by April 2016. The system will be installed and operated by CU Boulder, to which we are fiber connected with excellent connectivity. That system is anticipated to have more than 20X the computing power of CSU’s Cray, including GPUs (Graphics Processing Units) and Intel MIC (any Integrated Core) Accelerators.
  2. Two identical meetings have been scheduled to discuss with faculty and departments the “condominium HPC model,” where faculty and departments may buy compute nodes dedicated to their own purposes. Options being explored now and that will be discussed are i) installation at CSU, or ii) adding nodes to the HPC system mentioned above in item #1. These meetings are scheduled in Morgan Library’s Event Hall as follows; you are encouraged to attend:11/16: 10-11 AM
    11/20: 3-4 PM
  3. A visualization distance education course will be taught in Spring semester 2016 by visualization experts at CU Boulder, and is available to students at CSU under the auspices of GRAD 511, with myself as the instructor at CSU. The class will be taught once per week on Tuesday evenings from 6:30-9:00 PM. Students must register for both sections of GRAD 511, CRNs: 26375 and 26376. For more information, see Research Computing – Scientific Visualization Class – 2016.

If you have any questions concerning any of the above, please feel free to contact me forthwith.

RMACC HPC Symposium Announcement

The Annual Rocky Mountain High Performance Computing Symposium will be held Aug. 11-13, 2015 in Boulder, CO.

Advance program and registration information are available at It has many useful sessions for novice to experienced supercomputing researchers, programmers, administrators and users.

Please also encourage your students to submit a poster or attend. There are still a number of travel grants left to cover student registration and travel.

The symposium is being organized by the Rocky Mountain Advanced Computing Consortium (RMACC).

Metatranscriptomics Pipeline

In conjunction with the CSU Next Generation Sequencing Core, we have installed a metatranscriptomics pipeline on the CSU Cray, derived from a paper by Haas et al. Metatranscriptomics is a Next Generation Sequencing protocol for studying gene expression in communities of organisms. The NGS Core provides two DNA sequencers that are appropriate for metatranscriptomics research – Illumina NextSeq and Ion Proton. Data generated by these Core instruments can be fed directly to the Haas pipeline. The Cray handles several computationally intensive de novo assembly steps, thus improving time to solution. The Cray-Haas pipeline has been used successfully on microbiological samples. For more information about the metatranscriptomics pipeline and how you might use it on the Cray and in conjunction with Core facilities, contact the Core at
