RAW and MC production cycles ALICE Offline meeting June 21, 2010

2 RAW processing (1) LHC10b Pass 2 – since Friday The processing will be ready by tomorrow 4% ESDFriends filtering is on The gain is as expected – we are at 9% of the RAW data volume

3 RAW processing – 900 GeV Data almost perfectly recovered, 2.8% lost “integrity” check pass running now Rev-21 and OCDB “as is” Still to be updated for a proper Pass2 (Yves’ table)

4 Issues - memory Large ‘global’ memory leak in every job Since the 900 GeV chunks contain more events than 7TeV chunks, the leak is larger

5 Issues – memory (affects every job) Large ‘global’ memory leak in every job Since the 900 GeV chunks contain more events than 7TeV chunks, the leak is larger

6 Issues – various crashes Affect about 3% of the jobs Re-submission sometimes work – the bug(s) is intermittent and depends on the concurrent jobs/memory status Will make a coherent list at the end of processing
