EWK W production @ NLO

Sorry, solved for error. Apparently can also happens that poles do not cancel each other, as in https://answers.launchpad.net/mg5amcnlo/+faq/2720. But once #IRPoleCheckThreshold #PrecisionVirtualAtRunTime are modified, i fall back to the error in the message.. Any idea?

Thanks

I have recreated the error running in local the command.
From terminal, i get:

So I do see a first weird warning:
WARNING: Could not link /cvmfs/cms.cern.ch/slc7_amd64_gcc10/external/lhapdf/6.4.0-68defff11ffd434c73727d03802bfb85/lib/libLHAPDF.a at position: /home/abulla/newgen/genproductions/bin/MadGraph5_aMCatNLO/ewkwplvjj_NLO/ewkwplvjj_NLO_gridpack/work/gridpack/process/lib

and then the compilation seems to freeze and then crash with
RuntimeError: No active exception to reraise
things that I have never seen before.

My guess here is that cvmfs has some responsiveness issue and that some file can not be lined due to that and that the all process is stuck due to that. My advise would be to check that the size of the cvmfs local cache is large enough and the amount of squid associated to it. If you can not change the cvmfs configuration, maybe report to the sys admin handling it on your cluster and/or avoid to use it for such run.

Cheers,

Olivier
