Parallelizing event generation

Asked by Michele Lupattelli

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,

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.

Hi,

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

Cheers,

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
