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

  • Opteron 6134@2.3GHz, 16 cores - 147 x 17 WNs
  • Xeon E5-2695v2@2.4GHz, 48 cores - 437 x 9 WNs
  • Xeon Silver 4116@2.1GHz, 48 cores - 530 x 20 WNs
  • Xeon Silver 4214@2.2GHz, 48 cores - 572 x 16 WNs
Average HEP-SPEC06 score per core = (147*17 + 437*9 + 530*20 + 572*16)/(16*17 + 48*9 + 48*20 + 48*16) = 10.77

MadGraph cluster

  • Opteron 6134@2.3GHz, 16 cores - 147 x 18 WNs
  • Xeon E5-2670@2.6GHz, 32 cores - 336 x 3 WNs
Average HEP-SPEC06 score per core = (147*18 + 336*3)/(16*18 + 32*3) = 9.52

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.
