Gridpack generation - Error detected in generate_events pilotrun

Asked by Riccardo on 2020-11-09

Dear all,

I am trying to generate a gridpack by using MG5 2.6.5, the model SMEFTsim_A_U35_MwScheme_UFO_v3_1.tar.gz and the following MG strings (contained in my proc_card.dat):

set group_subprocesses Auto
set ignore_six_quark_processes False
set loop_optimized_output True
set complex_mass_scheme False
define p = g u c d s b u~ c~ d~ s~ b~
define j = p
define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
import model SMEFTsim_A_U35_MwScheme_UFO_v3_1-cHbox_massless
generate p p > e+ e- j j j j QCD=0 NP=1 NP^2==1 SMHLOOP=0
output ZV_e_cHbox_LI

But I got the following error:

Error detected in "generate_events pilotrun"

Hi,

This is a compiler issue related to the fact that your process/model generate very big matrix-element and that the compiler (in your case linker) is not able to handle such big case.

 The first things to do is to try to follow the advise prrinted on the screenn:
   /[...]/slc7_amd64_gcc700/external/gcc/7.0.0-pafccj/bin/../lib/gcc/x86_64-unknown-linux-gnu/7.4.1/../../../../x86_64-unknown-linux-gnu/bin/ld: failed to convert GOTPCREL relocation; relink with --no-relax

So you can add "--no-relax" options inside either the makefile and or in Source/make_opts.
(I guess you should update "LDFLAGS" in this case since this seems a linking issue)

Cheers,

Olivier

PS: Interference computation are likely to have phase-space integration issue since the phase-space integrator is not optimized for interference alone. So please consider that the cross-section/distribution are wrong up to the time that you have carefully check it.

Riccardo (ricbrs) said : #2

Hi Olivier,

The "--no-relax" option did not work, but I found out that modifying the several make_opts files by replacing

FFLAGS= -O -w -fbounds-check -fPIC
with
FFLAGS= -O -w -fbounds-check -fPIC -mcmodel=medium

worked. However the computation was too much time consuming and I had to stop it. I would like to use submit_condor_gridpack_generation but there are problems, maybe I shoul better open a dedicated question.

Thank you very much,

Riccardo
