W+0,1,2jets NLO gridpacks are failing

Asked by Marco Trovato on 2017-11-07

Hi,

I've been trying to generate W+0,1,2jets samples at NLO from

1) lxplus - locally
2) lxplus - lsf jobs
3) lxplus - condor jobs
4) login.uscms.org - CMS connect

Madgrapg version is 5.2.4

All jobs are either stuck or have failed because of memory issues [1] and no gridpacks were produced. I tried to increase the minimum desired memory to 4Gb but no luck. Do you have any suggestion on that?
Cards are here [2], Logs are here [3]

The last attempt I made is to raise the jet pt cuts from 10 GeV to 30 GeV and place a maximum 3.0 jet abs(eta) cut. With those changes I went a bit further in the generation (first cross section estimation was seen), but the gridpack production crashed here [4]. Do you know what the issue is? I get "Fortran runtime error: End of file" for the P2_dxux_tapvtuxux log file. Cards are here [5]

Please let me know if I can provide you with more info.
Thanks a lot
Best,
Marco

Hi,

The generation of the code requires typically a lot of RAM available.
To clean that memory space, the easiest is to close MG5aMC and then run the code via another instance.
If you really want to do everything inside the same session, importing a new model should free most of the RAM consumed by the generation of the code.

Since 2.4.0, we also introduced a mode using less RAM for the generation (see the message of the UpdatesNotes below):
        MZ: new NLO generation mode. It is more efficient from the memory and CPU point of
            view, in particular for high-multiplicity processes.
            Many thanks to Josh Bendavid for his fundamental contribution for this.
            The mode can be enabled with
            > set low_mem_multicore_nlo_generation True
            before generating the process.

Did you try that?

Cheers,

Olivier
