Overview of the Allocation Process for Computing Resources at the National Center for Atmospheric Research (NCAR)

Thank you for your interest in applying for computing resources at NCAR. Please take a few moments to review the following documents by clicking on their respective titles. Questions may be directed to alloc@ucar.edu .

Requests for Computing Services

  • Small Data Access Request Form - use when applying for small data access accounts. These accounts are allocated 50 GAUs for 3 years. Applicants must be at a U.S. non-profit research institution or at a UCAR affiliate.
  • Small Request Form -  use when applying for 2000 GAUs or less; does not require panel review. Send email to: alloc@ucar.edu to request an additional 4000 GAUs if you have used your initial allocation and are supported by an NSF award. Smaller amounts are available to graduate students and post-docs.
  • Large Request Form use when applying for more than 6000 GAUs with NSF support; requires panel review. Applicants should check the dates and deadlines of the next CISL HPC Advisory Panel (CHAP) meeting so that applications can be processed in time for review at this meeting.

Other Computing Allocations

  • Climate Simulation Laboratory (CSL) at NCAR provides high-performance computing and storage systems to support large, long-running simulations. The current solicitation is through May 2009. See the CSL Web Site for information on the next opportunity.
  • Classroom Use: University faculty who would like to use computer time for a course they are teaching should send e-mail to: alloc@ucar.edu or call 303-497-1229.
  • University scientists without NSF support in the areas of  atmospheric, oceanic, or related geosciences may request computing time on a cost-recovery basis. To do so, contact Ginger Caldwell by sending e-mail to: alloc@ucar.edu or by calling 303-497-1229. If you only need access to data use the Small Data Access Request Form
