* Performance per node.

The green values are measured according to CERN procedures.

Virtual Machines

Intel Xeon E5450 64-bit 25.90 3000 2 2 (1 modules) Xen HVM domU

Available Resources

This are the CPU recourses available on Phoenix. HEP-SPEC06 is measured according to the CERN procedures.

CPU # of cores HEP-SPEC06Sorted ascending kSI2k*
AMD Opteron 6172 240 1968 492
Intel Xeon E5540 1152 11520 2880
Total 1392 13488 3372

* 4 HEP-SPEC06 = 1 kSI2k

Possible Improvements

Not all of the jobs are CPU bound. Many of them are waiting for data. Therefore we could enable Hyper Threading and allow 12 jobs per WN. The other 4 cores will be reserved for the OPS/SGM and CSCS queue only.

  • Advantages
    • More CPU slots 1152 vs. 768
    • Better utilization of CPU
    • Better overall performance
    • Better match of CPU pledges for 2010 (about 13% more performance, see below)
    • Cores of CSCS queue available for testing; faster detection/debugging of problems
  • Disadvantages
    • Possibly less performance per single job slot
    • Accounting less accurate
      • Performance of a single job depends a lot on the number of running jobs / WN
