Supercomputing Resources & Allocation Strategies at NCAR-Wyoming Center (Bluefire)

The NCAR-Wyoming Supercomputing Center's Bluefire offers approximately 155,000 GAUs per year for computational use, divided into 60% one-time and 40% 30-day rolling allocations. This resource enables small job testing and larger project computations exceeding 1000 GAUs. Users are encouraged to maximize their allocations, testing jobs prior to execution to ensure optimal use. With 74,592 processor cores, 149 TB system memory, and a peak performance of 1.55 petaflops, Bluefire supports significant research endeavors with an increased allocation capacity of nearly 10X.

  1. Computing Resources for ASP NCAR-Wyoming Supercomputing Center

  2. Current Allocation (Bluefire) • ~155,000 gaus per year • 60% one-time use; 40% 30-day rolling allocation • Wiki page: https://wiki.ucar.edu/display/ASPGAU/Home • Strategy • 30-day allocation for small jobs (code testing, etc.) • One-time for larger jobs >1000 gaus • Leverage with Lab/Obs/Div allocations • Make sure you test before using one-time gaus • Use them or lose them

  4. Yellowstone and Allocations • 74,592 processor cores • 4,662 nodes • 149.18 TB total system memory • 1.55 petaflops peak • 29.8 Bluefire-equivalents • Allocations increased ~10X • HPSS data archive > 100 petabytes (108 Gb) • ASP allocation ~1.5 Mgau (1.5x106 gau) – mainly one-time usage • Transition in June 2012 • https://www2.cisl.ucar.edu/docs/allocations
