Subject: [OMPI users] How does OpenMPI decided to use which algorithm in MPI_Bcast????????????????
From: shan axida (axida2009_at_[hidden])

I had a glance at OpenMPI source codes and there are several algorithms for MPI_Bcast function.
My question is how is the algorithm decided to use in a given MPI_Bcast call? message size?
Anyone give me little detailed information for this question?

Thanks a lot.
