1.4 Allocation Policies


1.4.1 HPC Cluster Allocation Policy

  1. CHPC HPC clusters are available to qualified faculty and students (under faculty supervision). To request access to CHPC computer systems submit an online request. The general Ember and Kingspeak nodes are allocated by the process described below.  Users can however, run freecycle on these clusters if they do not get or have consumed their allocation.  Freecycle runs are subject to being preempted by jobs with allocation. Users can also run without allocation as owner-guest on the owner nodes on Ember, Kingspeak and Lonepeak, or as smithp-guest on Ash, again subject to the jobs being preemptable. Additionally, general nodes on Lonepeak does not have allocation; instead it is run in a "Fair Share" mode to balance usage between groups. There is no preemption on Lonepeak.

  2. Requesting allocations:
    All requests must be submitted by faculty with sponsored research projects (or their assigned delegate). CHPC uses core wall clock hour as the metric on the computational clusters (changed from a weighted service unit on April 2, 2015).

    After April 2nd, 2015 downtime

     Node description  Charge (wallclock hours*number of cores) 
    1 Ember node (12 cores per node) for 1 hour  12 hours (1.0 * 12 cores)
     1 Kingspeak node (16 core per node) for 1 hour  16 hours (1.0 * 16 cores)
    1 Kingspeak node (20 core per node) for 1 hour 20 hours (1.0 * 20 cores)
    Kingspeak node (24 core per node) for 1 hour 24 hours (1.0 * 24 cores)
  3. Research groups requiring priority time on a given cluster must submit a proposal requesting up to 4 quarters at a time and will be due the first day of September, December, March and June for allocations beginning the following quarter:

       Quarter         Quarter Definition      Approximate Request Due Date
     Winter  January 1 - March 31 December 1
     Spring  April 1 - June 30 March 1
     Summer  July 1 - September 30 June 1
     Fall  October 1 - December 31 September 1

    The request must be made by the principal investigator of the sponsored research project, who must be a faculty member, or a designated delegate.

  4. Submit your allocation request online using our web application:

    1. Authenticate to https://www.chpc.utah.edu/apps/profile/allocation_form.php using your campus uNID and password.
    2. Fill out the proposal form in detail. Please make sure to justify your request by explaining how much computational time you expect to require. Specific timings of your application runs, their size and duration are important in your justification. When completed, click on the "Submit Proposal" button.
    3. You may return and edit and fill in additional parts of the form. When you are satisfied with your proposal, change the "Request Status" setting near the top of the form to "Submitted - Ready for CHPC to Review". If you want to make additional changes after you have Submitted the form, please contact CHPC by sending email to issues@chpc.utah.edu.  
    4. Review Procedure:  Proposals will be evaluated by the CHPC Allocation Committee. The committee will meet during the month prior to allocation period, to consider allocations for the following quarter. Before each meeting, CHPC will provide an estimate of the resources available for allocation in the four upcoming quarters as well as any other technical information the committee may deem appropriate. 
  5. "Quick" Allocation:  
    CHPC allows faculty with sponsored research and without a current allocation to submit allocation proposals after the aforementioned deadlines with some restrictions. The request cannot be for more than 30,000 wallclock core hours, and the allocation is for the current quarter. There are no renewals of Quick Allocations. The review of these proposals is expedited and awards are given in a few days. Submit your allocation request online using our web application.
    1. Authenticate to https://www.chpc.utah.edu/apps/profile/allocation_quick_form.php using your campus uNID and password.
    2. Fill out the proposal form in detail.  When completed, click on the "Submit Proposal" button.
    3. You may return and edit and fill in additional parts of the form. When you are satisfied with your proposal, change the "Request Status" setting near the top of the form to "Submitted - Ready for CHPC to Review". If you want to make additional changes after you have Submitted the form, please contact CHPC by sending email to issues@chpc.utah.edu.
    4. Quick reviews will be performed by the Director and/or the Associate Director of CHPC, and awards given for up to 30,000 core wall clock hours for the current quarter only.
  6. Unused Allocations: Allocations unused in any quarter cannot be carried over to the next.
  7. Users without allocation and those whose usage exceeds their groups allocation will run in the system in "freecycle" mode, running at lowest priority and depending on the individual cluster policies, may be eligible for pre-emption. See Policy 2.1 General HPC Cluster Policies to see the individual cluster policies.]

1.4.2 Virtual Machine Allocation Policy

CHPC can provision virtual machines for sponsored research projects when the application or tools required do not fit with our other HPC resources (i.e. computation clusters). To request a virtual machine for these purposes, please send the request via an email to issues@chpc.utah.edu.  The request must come from, or be approved by a PI who has been setup as a CHPC PI. Please provide the following information :

  • A project name and brief description of your research. Please include sources of funding, including funding agency, grant/contract numbers.
  • Operating System - must be one of the following
    • Currently supported versions of Red Hat Enterprise (currently RHEL 6 and 7)
    • Currently supported versions of Windows Server (currently 2008 R2 and up)
    • Other (Please provide a detailed justification why your application cannot use one of the above operating systems)
  • Number of cores (1 or 2). If you require more than 2, you will need to provide justification.
  • Amount of RAM required. A justification is required if requesting more than 2 Gb.
  • Disk Space requirements. A justification is required if requesting more that 50 Gb. Include any backup requirements.
  • The desired IP name for the host
  • The requested security model for this host. Choices are:
    • CHPC Administered
    • Self Administered (NOT an option for virtual machines with personal health information (PHI) data.)
    • Shared Administration (please provide justification for this choice).
  • Name of the administrator of this VM
  • Detail the security requirements of this host including if there will be any personal health information (PHI) data involved in the project. If there is PHI, additional information such as Institutional Review Board (IRB) documents and software descriptions will be required. VMs provisioned for projects using PHI data will be provisioned in the Protected Environment and will require users be HIPAA trained in addition to meeting the standards for running in the CHPC Protected environment.
  • The completion of a Faculty Resource User Agreement (FRUA) is required.
