1. Re-Reconstruction Of Generated Monte Carlo In a McFarm Context D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

2. Objective Manage MC reprocessing with McFarm –No massive changes – flexible  –D0RunII, ups/upd environment sufficient – packages, rcp’s, data –mc_runjob handle reprocessing –Scriptable procedure –File outputs certified for SAM storage D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

3. Status August 1 U. Michigan – NPACI cluster  3 scripts –Job submission, SAM project handling (make_npaci.py splitProject.py, ) –Run control – referred to other scripts that provided job creation (npaci_jobs.sh) –Not exactly applicable to McFarm –Left out crucial info (binaries, rcp’s) –Yet were still informative (nothing exotic needed, adaptable to McFarm) D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

4. Further Investigation RCP’s crucial –Where do the come from? –What are they? –Can they and their parameters be user specified like Request system used with mc_runjob? Or have to craft mc_runjob macro and use reg_job? D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

5. Action Plan Make job dir on farm node. Locate RCP’s and alter for single input file and output files with no SAM use. Run re-reco to completion Inspect output, logs Shows SAM not needed during running, no non-MC database or binary is needed, and that the job can be encapsulated to one input/output. D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

6. Release p14.02.00 Copy McFarm run directory in the d0reco phase to a test area Modify file list to use McFarm generated reco file Copy runD0reco_mc_reprocess.rcp and DropChunks_ReprocessDST.rcp to d0reco rcp dir Modify run_d0reco.sh rcp file to runD0reco_mc_reprocess.rcp, rename to run_d0rereco.sh, run it D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

7. p14.02.00 Results Job completed producing reco and tmb files Great! No extra stuff, just D0RunII. Where’s the metadata? Right RCP’s? Only >p14.03.00 certified for re- reco. Try it again. D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

8. p14.03.02 Results Reprocess rcp's for detector subsystems –Find them all and place in the proper sub dir of the re-reco test area Job completes producing reco and tmb files Where’s the metadata? Right RCP’s? Also shown that can re-reco in mc_runjob structure D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

9. CAB/NPACI Style Use d0tools package –rund0exe runs d0reco –cabSubmit.py submits job, SAM handling –Still where’s the metadata? Not d0reco rund0exe takes USERPOSTSCRIPT argument – provided by env. var. at NPACI Still unknown how it’s produced(?) Need script(?) D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.

10. Developments & Status mc_runjob version re-reco specifically enabled available No apparent structural incompatibilities for McFarm to be able to re-reco Has metadata producer been found? Anybody know the latest? D0SAR@OUD0SAR@OU, 2003/09/26 Joel Snow, Langston U.
