LHAPDF6 and aMC@NLO

[Francesco Giuli]

Hi all,
I'm studying Z + jets events with the FxFx merging (up to 2 extra jets).
I have a problems: if I use a set of PDFs non built in aMC@NLO (e.g. NNPDF-3.0, dataset number = 260000) I got something like:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:
#0 0x7F80AE12D2F7
#1 0x7F80AE12D8FE
#2 0x7F80ACB8D69F
#3 0xB24D7C
#4 0xB2A59B
#5 0xB2350D
#6 0xB14046
#7 0x476914
#8 0x477B8C
#9 0x7F80ACB79D5C
#10 0x413CBC

while, If I use a built in PDF library everything works fine. Moreover, If I study Z + jets with only 1 extra jets aMC@NLO works fine also with a a set of PDFs non built in it.
Any clues?

Thanks,
Francesco

Ciao Francesco,
this bug should be solved in 2.2.3, see also

Can you please confirm?

Cheers,

Ciao Marco,
yes I can confirm!

Ciao Marco,
Thanks a lot, no worries! In attachment you can find all the files you asked me ( I attach also the input/mg5_configuration.txt if you want to take a look).
As regards the LHAPDF6 version, I’m currently using 6.1.4.

Cheers,
Francesco

Ciao Francesco,
I have tried to run with your cards and lhapdf6.1.5 on our SL6 cluster, and it terminated successfully the first step (setting up grid) after ~ 2.5 hours
So it looks like i am not able to reproduce your error (unless it happened at a later step)...
One thing you can do is to try to do a
make clean
and edit the
Source/make_opts file adding -fbacktrace to the FFLAGS
also, you have to remove or comment the
strip madevent_mintMC
line from
SubProcesses/makefile_fks_dir
in order to have more debugging informations...

Let me know what you get.
Cheers,

Marco

Ciao Marco,
I was very very busy during the last two weeks sorry. I'm installing lhapdf-6.1.5 (let see if the version 6.1.4 could be the problem or not) then I'll follow what you answered me in the previous post and I'll let you know

Cheers,

Title:
  LHAPDF6 and aMC@NLO v2.2.2

Status in MadGraph5_aMC@NLO Generator:
  New

Bug description:
  Hi all,
  I'm studying Z + jets events with the FxFx merging (up to 2 extra jets).
  I have a problems: if I use a set of PDFs non built in aMC@NLO (e.g. NNPDF-3.0, dataset number = 260000) I got something like:

  Program received signal SIGSEGV: Segmentation fault - invalid memory
  reference.

  Backtrace for this error:

  #8 0x477B8C
  #9 0x7F80ACB79D5C
  #10 0x413CBC

  while, If I use a built in PDF library everything works fine. Moreover, If I study Z + jets with only 1 extra jets aMC@NLO works fine also with a a set of PDFs non built in it.
  Any clues?

  Thanks,
  Francesco

Ciao Marco,
I don't know why I cannot reproduce the error anymore because I got a new error at the end of 'output name_of_the_output_folder' command (as you can see below:

INFO: Use Fortran compiler /afs/cern.ch/sw/lcg/external/gcc/4.8.1/x86_64-slc6-gcc48-opt/bin/gfortran

Please report this bug on https://bugs.launchpad.net/madgraph5
More information is found in 'MG5_debug'.
Please attach this file to your report.

). Have you ever seen something like this? I've tried to re-install the latest version of aMC@NLO (2.2.3) but it still doesn't work. Any clues on how to solve this issue?

Cheers,
Francesco

[Francesco Giuli (francesco-giuli)]

This is the MG5_debug file...

[marco zaro (marco-zaro)]

Cia Francesco,
i have already seen a 'cannot allocate memory' error, in a thread of yours (https://bugs.launchpad.net/mg5amcnlo/+bug/1406146/)
)It was not clear to me how/if you solved it...
Let me know,
Cheers,

Marco

[Francesco Giuli (francesco-giuli)]

Ciao Marco,
it's really really weird because now I got a new error (at the same point where I got the previous one):

^[[1;31mCommand "import /afs/cern.ch/work/f/fgiuli/public/MG5_aMC_v2_2_3/myprocess_card.dat" interrupted in sub-command:

If I use the developers releases of aMC@NLO 2.2.3, everything it is fine (also using an external PDF set).
I really don't know

Cheers,
Fra

[marco zaro (marco-zaro)]

Ciao Francesco,
can you check the new 2.3 version if it is still bugged?
Thanks,

Marco

[Francesco Giuli (francesco-giuli)]

Ciao Marco,
I completely forgot to answer... Anyway I can confirm that the new version is not bugged.

Best,
Fra
