Computing Resources

CP3 members have access to the Manneback UCLouvain cluster. This cluster is made of two parts:
  • The CP3 ingrid cluster described below, providing 2500 computing cores with high priority to CP3
  • The Manneback UCLouvain cluster, shared with other UCLouvain researchers, providing 1600 computing cores

Performance

CMS/LHC Tier 2 - Ingrid cluster

  • Xeon E5345@2.33GHz, 8 cores - 63.9 x 14 WNs
  • Xeon L5420@2.5GHz, 8 cores - 70.4 x 29 WNs
  • Opteron 6134@2.3GHz, 16 cores - 147 x 29 WNs
  • Xeon E5-2670@2.6GHz, 32 cores - 336 x 3 WNs
  • Xeon E5-2695@2.4GHz, 48 cores - 437 x 10 WNs
Average HEP-SPEC06 score per core = (63.9*14 + 70.4*29 + 147*29 + 336*3 + 437*10)/(8*14 + 8*29 + 16*29 + 32*3 + 48*10) = 9.1

MadGraph cluster

  • Opteron 2380@2.5GHz, 8 cores - 75.0 x 5 WNs
  • Opteron 6134@2.3GHz, 16 cores - 147 x 31 WNs
Average HEP-SPEC06 score per core = (75.0*5 + 147*31)/(8*5 + 16*31) = 9.2

Other resources

CP3 members also have access to the computer clusters funded by CECI. A detailed listing of the CECI computing resources can be found here. These clusters are located across universities of the French Community of Belgium (Communauté française de Belgique) and amount for a total of 8300 computing cores.
