[mpich-discuss] IBM BG/Q collectives

Hello,

I have a couple of questions about BG/Q collectives and would appreciate
any help.
I was wondering if Do IBM BG/Q MPI collectives use binomial tree?
Once I find the name of the algorithm used by the MPI collective routine
using MPIX_Get_last_algorithm_name, is there a quick reference or guide to
check how it is implemented?

Thanks!
Jen
