How to process E891 data off-line
How to arrange multiprocessing of E891 data off-line
In order to speed up the off-line data processing and reduce
the risk to loose time due to physgi01 shutdown the following
way of multiprocessing may be used:
- Running E852 Event Dispatcher (example)
- Feeding Event Dispatcher by data from the proper file (example)
- Running E891 analyzers as background jobs (example)
- Convenient script which has to be modified for each run make_itapes
- One more script make_ntuple
- Off-line Processing Logbook off-line.log
- For continuous processing one may use (after the proper change of run numbers)
the following chain of scirpts: checkFinished_1,
checkFinished_2 etc.... the first script calls the
second as soon as it has done its job, and so on.
- To check how many event and spill records went through the Dispatcher do the command:
"tail /scratch10/e891/wrk/feed.log"
