A binary tree is the implementation of last resort. See these papers for details of the MPI collective implementations on Blue Gene: - http://dx.doi.org/10.1177/1094342014552086 - http://dx.doi.org/10.1109/HOTI.2009.12 (this is not an inclusive list) http://lists.mpich.org/pipermail/discuss/2015-March/003754.html has some related info.

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
