For gridengine, as reported by the batch system. you expect in general for muticore jobs the cpu time to be larger than the wall time. Not sure how this makes its way to apel.
e.g for 100% efficient jobs, if for a single core job cputime=wall clock time, then for an 8 slot multi core job the cpu time = 8* wall clock time.

Dear all, this is another thread we need to check. We have receipes to enable accounting for CREAM CEs and ARC-CEs should be working out of the box, but I'd like sites to check their status. There seem to be some discrepancies at some sites. We'd like to understand where they are coming from i.e. have the sites published all the data? Have they enabled the multicore counting in CREAM-CE [1]? Is it a portal problem? Next week we have been asked to report at the WLCG MB about this so any info about discrepancies we need to investigate (or also if it works perfectly) you can send us is much appreciated. thanks cheers alessandra [1] https://twiki.cern.ch/twiki/bin/view/LCG/MulticoreTFReports#Report_18_09_2014 -- Respect is a rational process.
