Request5: PWG4 - dielectrons, 10M minbias BiBi@9.46

This is a PWG4 request for a new Monte Carlo production. The production is for Bi (83/209) +Bi (83/209) collisions at 9.46 GeV, which is the most probable beam configuration for day-1.

Please find below the request details:

inputfile (307 Bytes)
runMC.C (10.2 KB)
reco.C (8.7 KB)
MpdDecayConfig.txt (357 Bytes)

This is a Geant4 based general-purpose project, which includes simulation of the MPD-ECAL (v.3 geometry) and has enhanced (x20) probabilities for light vector meson decays to ee+X channels. Since original branching for such decays is 10^-4-10^-5, the enhancement does not affect the simulation of hadrons. Decays of short-lived resonances (to have realistic peak widths) and pi0/eta-meson are managed by Pythia8.

The simulation project consists of a few stages:

  1. Events are generated by UrQMD. It should be run with an attached inputfile, which was set up to generate 500 minbias BiBi@9.46 collisions. Some of the particles are requested to be stable in the input file to be further decayed in the mpdroot.
    Important : The value of ‘rsd’ parameter should be set as a unique integer for each UrQMD run.
  2. Make a fresh check-out of the dev version of the mpdroot and then compile. The main changes in the code were done by Aug,1
  3. Replace file gconfig/MpdDecayConfig.txt with the attached one.
  4. For simulation, please use the attached runMC.C macro.
  5. For reconstruction please use the attached reco.C macro. It produced standard DST files.

Notes:

  1. In this production, we do not need to store any intermediate files, wee need only the DSTs.
  2. To validate the production configuration, we need ~ 200,000 events reconstructed for QA.
  3. The output files will have to be copied and stored at NICA cluster.
  4. The ‘mpdroot’ should be tagged for this production.

Now all available resources are occupied by production for pwg3. It takes about a week to complete the current production. I’ll try to find an option to process 100,000 test events. Again there was no notification about a new topic on the forum. I don’t check the forum every day.

It’s OK, I understand.

Just for the record, I have got the notifications.

100,000 events on the NIСA cluster in:
/eos/nica/mpd/sim/data/exp/dst-BiBi-9.5GeV-mp07-20-pwg4-250ev/BiBi/09.5GeV-mb/UrQMD/BiBi-9.5GeV-mp07-20-pwg4-250ev-1

Thanks! I will need a few days to check the output.

Production for pwg3 has been completed. I’m ready to start next one.

Спасибо за информацию. При проверке первых 100,000 событий я нашел баг в коде и он уже был исправлен. Однако, я хотел бы взять тайм-аут на несколько дней. Возможно, появятся дополнительные изменения.

Для меня это даже лучше. Может успею еще один ресурс для продакшена обкатать. Многого от него ждать не приходится, но все же.

Sorry for the long delay. We found a bug in the test production and also there was a progress in the code developement. As a result, we decided to reformat the request. The original request (on the very top) has been modified to reflect the changes. The production should be restarted from scratch. For the test, we need ~ 200.000 events.

I tried to run the current version of MPDroot with your runMC.C. Script drops with this error. The standard script works with both G4 and G3. Maybe I have the wrong script?

I do not see any problems with the runMC.C script, I just checked and it worked with my libraries. I also do not see anything obviously wrong in the GIT repository, all needed files seems to be updated. Just in case, did you copy MpdDecayConfig.txt in mpdroot/gconfig/ before running the runMC.C?

Just for the record, the problem was in DOS format of the MpdDecayConfig.txt file from the first post. Fixed.

I see only miniDSTs in the directory. Could you please copy the full size DST files needed for the production? Thanks.

Sorry, I answered in three topics at once and wrote the path to the files for pwg3 in your topic. Your files in: /eos/nica/mpd/sim/data/exp/dst-BiBi-9.5GeV-mp07-20-pwg4-250ev/BiBi/09.5GeV-mb/UrQMD/BiBi-9.5GeV-mp07-20-pwg4-250ev-1

Thanks, now it works. I need some time to run the tests.

The test files are fine. Lets proceed with the full production. Thanks.

Data on the NICA cluster in /eos/nica/mpd/sim/data/exp/dst-BiBi-9.5GeV-mp07-20-pwg4-250ev/BiBi/09.5GeV-mb/UrQMD/BiBi-9.5GeV-mp07-20-pwg4-250ev-1,2,3,4. Production took longer due to problems and routine maintenance on clusters

Thanks, will have a look!

Hi, could you please tell me how did you fix the above error. " There was a crash.
This is the entire stack trace of all threads:

#0 0x00007fc0ebea945c in __libc_waitpid (pid=13571, stat_loc=stat_loc

entry=0x7ffe762b4be0, options…"

I have a text file named “MpdDecayConfig.txt” in my mpd/gconfig directory. I checked using vim that it’s of DOS format and then I deleted that and created another text file with the same name “MpdDecayConfig.txt” and copied all the contents of old file to the new one.

Now, even after performing this step, I am still getting the same message "There was a crash… "

Could you please help me in resolving this?

Thank you in advance!
