HS06 is the HEP-wide benchmark for measuring CPU performance. It has been developed by the HEPiX Benchmarking Working Group in order to replace the outdated “kSI2k” metric.
The goal is to provide a consistent and reproducible CPU benchmark to describe experiment requirements, lab commitments, existing compute resources, as well as procurements of new hardware.
HS06 is based on the all_cpp benchmark subset (bset) of the widely used, industry standard SPEC® CPU2006 benchmark suite. This bset matches the percentage of floating point operations which we have observed in batch jobs (~10%), and it scales perfectly with the experiment codes.
HS06 is the official CPU performance metric to be used by WLCG sites since 1 April 2009.
Although the HS06 benchmark was initially designed to meet the requirements of High Energy Physics (HEP) labs, it is by now widely used also by other communities.
