Segmentation Fault

Reported by: new Owned by: Peter Richardson
Priority: major Milestone: Herwig 7.1.2
Version: 7.1.1 Keywords: Powheg LHE
Cc: ceylanm@…

Description

Hi
I am trying to import PowhegBox? generated LHE files to Herwig++. When I execute the run card after successful read, I am having "Segmentation fault (core dumped)" error.
Possibly the problem arises due to the not set variables according to read card. Event I set number of events as 50k I see 1000k events in .run file.
Herwig read somehow could not take generator specific number of events parameter as input.

So could you please email the LHE file to herwig@… and add your email address in the CC so we can get in touch we you.

Thanks

I have already send an email about it.
I send yet with run cards and LHE file generated from PowhegBox?.
Thank you.

So with the current head of our release branch I can generate 50 000 events using your LHE and input files without any crashes, there's then a hard stop when it runs out of events but that's fine as it does the normal termination and output the hepmc file.

Exactly which versions on Herwig and ThePEG are you using and how many, if any events, were generated before the crash?

Thanks

Peter

Really?
I have setup the Herwig by bootstrap, versions are below
Herwig 7.1.2
ThePEG 2.1.2

None of events are generated, empty output files are being created when I run.
I will try it on another pc.

Can you send .run file generated?
Is that the same with I sent? If so, why number of events are 1m and does it have any meaning?

Thank you

Same result again
Can you pls send the .in and .run files?

Strange, it seems trying to get previously installed Pythia

Sorry for the spam like comments of mine
I think the problem occurs from the pythia defined paths in bashrc
When I comment them out, Herwig started to run
Thank you for your effort Peter
