Description

    Extract from the minutes of the WLCG MB, 5 June (https://twiki.cern.ch/twiki/pub/LCG/MbMeetingsMinutes/LCG_Management_Board_2007_06_05.htm):

    Decision of the WLCG Management Board: The MB agreed that, until the HEPiX benchmarks are defined, the proposal distributed by L.Robertson is accepted.

    This proposal is contained in the note distributed to the MB "Proposal for an interim CPU capacity metric for WLCG"*. This uses the methodology of GridKA (i.e. run one copy of the SPEC CPU2000 code per core), uses the compiler flags as specified by the Architects Forum (-O2 -pthread -fPIC), with a scaling factor of 1.5 (reflecting the lower level of compiler optimization compared with the current GridKA benchmark test).

    A HOWTO section with benchmark script and configuration files is available on the HEPiX pages: see http://hepix.caspur.it/processors/ .
