Pythia 8 stucks on shower jobs

Asked by Maksym Ovchynnikov on 2019-04-21

Hi!

I am trying to simulate the processes

generate process p p > h [noborn=QCD]
add process p p > h j [noborn = QCD]

and then to interface it to pythia for showering and hadronization. pythia6 runs fine, while pythia8 stucks on shower job (as far as I can wait).

The parameters regarding matching/merging in the run_card.dat are

 1 = ickkw ! 0 no matching, 1 MLM
  1.0 = alpsfact ! scale factor for QCD emission vx
  False = chcluster ! cluster only according to channel diag
  4 = asrwgtflavor ! highest quark flavor for a_s reweight
  False = auto_ptj_mjj ! Automatic setting of ptj and mjj if xqcut >0
                                   ! (turn off for VBF and single top processes)
  30.0 = xqcut ! minimum kt jet measure between partons

I also tried to set the parameters in pythia8_card.dat manually:
qcut=45
Merging:nJetMax = 2.

The terminal output when launching is the following:

In addition, the size of .hepmc files in split_0 and split_1 folders constantly increases during the run and can be as large as 1 GB each. It seems that this is abnormal...

Additional info. If I run run_shower.sh, then it generates (in terminal) some event listing, after the end of which it writes typically the following errors and warnings:
 PYTHIA Error in StringFragmentation::fragment: stuck in joining
 PYTHIA Error in Pythia::next: hadronLevel failed; try again
 PYTHIA Warning in StringFragmentation::fragmentToJunction: bad convergence junction rest frame
Pythia::next(): 1000 events have been generated
 PYTHIA Error in StringFragmentation::fragmentToJunction: caught in junction flavour loop
 PYTHIA Warning in Pythia::check: not quite matched particle energy/momentum/mass

The .log files in split folders contain the following information:

Is there any new data approximately how to clear up this problem? I would actually respect any help on this site https://campingspy.com/best-winter-camping-tents-with-stove/ because I've tried in a brand new pc, with the maximum current model of both MG5 and Pythia8 and not anything works.

Can you help with this problem?
