Number of events using the gridpack

Asked by Gilberto Tetlalmatzi on 2020-08-05

Dear Administrators

Apologies in case of asking a question which has already been solved, but this is quite important and I would like to be completely sure about the answer. I created a gridpack using 50 events. Is there any issue if I generate 100 events or more with this gridpack?

Thanks in advance!
Gilberto

For official gridpack, they are no issue (even for more larger gap). Acttually the number of event requested is not used when you set gridpack to True.

Now, if you use gridpack from CMS framework (and maybe ATLAS), they have implemeted an option to include post-processing in the gridpack (I think in particular to MadSpin) the iniitialisation of such post-processing can sometimes requires a minimum number of events in order to guarantee the precision (this is the case for MadSpin). So their I would be careful (this is why I do not include the options of such processing in our code).

Cheers,

Olivier

Dear Oliver

Thanks a lot for your answer! We are using a standard gridpack, nothing from CMS or ATLAS framework.

Cheers

Gilberto
