Hello All, After some further preparations, the 2021 trigger skims are launched. Outputs will be going to /cache/hallb/hps/physrun2021/production/evio-skims. I broke the run list from Norman into 5 lists, and started with the first 20% in one batch, all submitted. I'll proceed to the other 4 batches over the holidays, assessing tape usage as we go. -Nathan > On Nov 29, 2021, at 3:39 PM, Nathan Baltzell <[log in to unmask]> wrote: > > The 10x larger test is done at /volatile/hallb/hps/baltzell/trigtest3 > > -Nathan > > >> On Nov 29, 2021, at 2:52 PM, Nathan Baltzell <[log in to unmask]> wrote: >> >> Hello All, >> >> Before running over the entire 2021 data set, I ran some test jobs using Maurik’s EVIO trigger bit skimmer.

The total is 10% and not a problem if these skims are expected to be useful. The outputs are at /volatile/hallb/hps/baltzell/trigtest2 if people are interested to check things. >> >> A 10x larger test is running now and going to /volatile/hallb/hps/baltzell/trigtest3 and should be done in the next couple hours. >> >> ************ >> >> Note, it would be prudent to do this *only* for production runs, those that would be used in physics analysis, to avoid unnecessary tape access. By that I mean removing junk runs, keeping only those with some significant number of events, and only keeping those with physics trigger settings (not special runs). For that we need a run list. I think we have close to a PB, but I remember hearing at the collaboration meeting that at least 20% is not useful for the porpoises of trigger bit skimming. >> >> -Nathan_______________________________________________ >> Hps-analysis mailing list >> [log in to unmask] >> https://mailman.jlab.org/mailman/listinfo/hps-analysis > ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
