Description
Hi,
I'm running Delphes3 from MadGraph5. I want to generate a large number of events (10M). The Pythia8 showering is correcly split into 32 sub-processes (where 32=no. of cores). However, at the end of the run, it looks like the files are merged before they are fed into Delphes3. It takes several days to run Delphes on 10M events one by one...Is it possible to run Delphes in parallel at all? Is that a feature of Delphes or MadGraph?
Thanks,
Riccardo
