Root and MPI

General Chat

Dear all,
I would like to generate events using ROOT, but running ROOT on a cluster, otherwise it would be very time consuming . Is it possible to use MPI?

Thanks,
Pilar

I’m sure somebody else will reply with the “real answer,” but you shouldn’t need MPI to do what you want. Simply setup your jobs to take an argument (e.g., a random seed) from the queuing system (e.g., $(Process) on some variants of condor), so that each job/section doesn’t duplicate another.

Good luck,
Charles
