Hardware

OP5707XG

  • Motherboard: SuperMicro X11DPL-i
  • Processor: Intel(R) Xeon(R) Gold 5222 CPU @ 3.80GHz; 8 cores
  • RAM: 32 GB

Software

  • Platform: HYPERSIM
  • Compiler: Intel 2019 (19.03.199)

Results

  • Number of core(s): 6
  • Minimum time-step: 45 us *
  • Total average execution time (sum on all cores): 210.6 us

* Performance under transient conditions varying considerably depending on the study type, this benchmark measures the minimum achievable time-step without overruns in steady-sate conditions. A rule of thumb is to consider 10 to 20 % buffer time for calculations under transient conditions.
