Subject: [OMPI users] OpenMPI MPI_Bcast Algorithms
From: shan axida (axida2009_at_[hidden])

Hi all, I think there are several algorithms used in MPI_Bcast. I am wondering how are they decided to be excuted ? I mean, How to decide which algorithm will be used? Is it depending on the message size or something ? Would some people help me? Thank you!
