HYBRID PARALLEL MODE SCHEME

Post by Andrea » Sun Mar 25, 2018 8:29 pm

I was wondering how the hybridMPI-OpenMP simulation mode works. Is the batch size split into several CPUs (master/slave scheme)? How the OpenMP threads behave with this division of the batch?

Batch size is split between MPI tasks. OpenMP parallelization is carried out by running each history on a separate thread.
