Parallelizing event generation

Asked by Michele Lupattelli on 2020-03-05

Hi,

How can I launch generate_events multiple times simultaneously? I tried to do it submitting multiple times the same job into the cluster, but only the last submitted job survives, while the other ones crash. I would expect each job to create the folders "run_01", "run_02" and so on inside the folder "Events".

Thank you in advance.

Cheers,

Michele

Hi Michele,

This is not possible.

Hi,

So, if I want to generate 500K events, is the only option multi_run? Or there is a way to parallelize the jobs?

Cheers,

Michele

Hi,

Are you speaking about LO or NLO generation since the options are not exactly the same in the two modes.

Cheers,

Olivier

Hi,

I am mainly interested in NLO mode, since LO event generation is quite fast.

Cheers,

Michele

HI,

Then I would here just ask 500k events in the run_card
but specify the paramater
nevt_job (in the run_card as well_
to something like 5000 (I actually do not know what is the optimal value for that parameter)

Cheers,

Olivier
