Failing to generate gridpack for QCD process

Asked by Michele Selvaggi

Dear experts,

I am trying to generate a gridpack for the following process at 100 TeV with 2.5.5:

define bot = b b~
generate p p > bot bot bot bot j

the 4b system has to recoil against the light jet with pT> 500 GeV. I also add DR(bb) > 0.1 and ptb > 100 GeV.
This takes a long time to generate but works.

If I ask on top of that a 200 < m(bbbb) < 600 GeV the gridpack generation fails with error (*). The problem seems to be the upper bound requirement m(bbbb) < 600 GeV that I ask in cuts.f.

I am attaching cuts.f, run_card.dat and a log of one of the SubProcesses.

 Any help on how to generate this process?

Thanks

Hi,

What is the content of the log file associated to the jobs that failed?

Please remember that adding cut by hand in cuts.f can be very dangerous for the convergence of the code.
Since the code is not optimised on those cuts. So please always validate that you have the same shape cross-section from samples generated without such cuts before putting such gridpack in production.

> The problem seems to be the upper bound requirement m(bbbb) < 600 GeV that I ask in cuts.f.

Upper limit is quite hard to handle at the phase-space level indeed. (Especially for background). So this is not too surprising.

Cheers,

Olivier

Hi Olivier,

thanks for your answer.
See below two log files corresponding to the two subprocesses ['G356', 'G357']:

https://drive.google.com/drive/folders/0B3UJDbSmnhWoVm5VSVRFdmhSc0E

Isn't it possible to actually hack the phase space point generation to account for that upper cut value?

Cheers

Hi,

This sounds to be a filesystem issue.
The crash is linked to a missing file, but that file actually exists in the log file that you provide to me.
The only solution for that is to resubmit the jobs as it is the default in the code.

Cheers,

Olivier

Hi Olivier,

I have been resubmitting this process at least 7 times, and never got any output, so this is obviously not a filesystem issue.
There is some subprocesses that consistently take forever and eventually fail after several hours of running.

Would you please mind trying this process out?
I think I have supplied all necessary ingredients: (process, run_card, cuts.f)

Please let me know if you need something else.

Cheers
Michele

Hi Michele,

The error is Cleary in this case:
 file missing: /afs/cern.ch/work/s/selvaggi/public/MG5_aMC_v2_5_5/bbbbj/SubProcesses/P1_gg_bbbxbxg/G357/results.dat<http://cern.ch/work/s/selvaggi/public/MG5_aMC_v2_5_5/bbbbj/SubProcesses/P1_gg_bbbxbxg/G357/results.dat>
But that file is present in the directory G357, that you send.

This sounds really a file system issue. Trying it on a different machine does not make that much sense to me.
I also check the log.txt and default_log.txt of that director and they both indicate that such job is working nicely.

So from what you send this time, I do not see the point to run it myself on my laptop to see it.

Cheers,

Olivier

Hi Olivier,

so I have re-rerun the process on ingrid and find NaN cross-section.
You can have a look here for example (you should have access to the that space, otherwise please let me know):

/home/fynu/mselvaggi/storage/MG5_aMC_v2_5_5/bbbbj/SubProcesses/P1_gg_bbxbbxg/G78/run_01_log.txt

That is not the only SubProcess with NaN cross-section, there are also G112, G114, G121, G122, G423, G424, G425, G431, G432...

Cheers

Hi Michelle,

You did not give me write/exec access on those directories.
Impossible for me to run gdb on those without such access as we discuss by skype.

Cheers,

Olivier

Hi Olivier,

you should now have access to:

/home/fynu/mselvaggi/storage/MG5_aMC_v2_5_5/bbbbj/

and all subfolders...

Note that the environment for this process can be obtained via:

module load pheno/pheno_gcc49

Thanks
Michele

Hi Michele,

The problem seems related to the MC over sub-grouping.
You can set mc_grouped_subproc to False

Will see how to fix it in a nicer way.

Cheers,

Olivier
