Cannot run a nlo ufo model

Asked by Georgios Polykratis

Hello,

I use a nlo model to generate some gluino production.

import model new_EWKino_NLO_UFO-default --modelname
generate p p > go go [QCD]

The generation is successful but I have a problem every time I try to create an output folder. The model works fine for other collaborators so I suspect there is something wrong with the HEPtools. So when I try to create the output I get this, and the process is killed:

MG5_aMC>Killed

I am expecting the nnpdf3.0 to be used which I installed at the HEPTools/lhapdf6/share/LHAPDF/ folder but at the output folder ppgogo/lib/Pdfdata/ (of the failed attempt) I see that only the NNPDF23 has been used.

Concerning the warning about the lhapdf, its path in the MG5_debug file is set correctly to /home/giopolykra/MG5_aMC_v2_6_6/HEPTools/lhapdf6/bin/lhapdf-config.

Ps: I am using MG5_aMC_v2_6_6

Looks like you are running on a machine with not enough RAM in order to generate such process.
You can try to use the option
set low_mem_multicore_nlo_generation True
combine to a small amount of core to try to make it trough.

Off course a simpler method is to run on a machine with a larger amount of RAM

Cheers,

Olivier

This is weird since my machine has 7.7gb of usable memory. I tried the option for small memory usage after a fresh installation of madgraph 2.6.6 installing zlib, boost, lhapdf6, hepmc, pythia8, ninja, oneloop and collier

after generation I have
11 subprocesses with 766 real emission diagrams, 53 born diagrams and 2685 virtual diagrams

but despite that I get a new error

Looks like a new error. can you copy/paste the debug file?
