No documentation yet. If you want to understand how it works and what exactly "highly optimized" means please look for the collectives papers on this page (http://www.netlib.org/utk/people/JackDongarra/ papers.htm). In few words, we have multiples algorithms and we tune them based on the net

George Thanks for the info. When you say "highly optimized" do you algorithmically, tuning, or both? In particular I wonder if OMPI optimized collectives use the divide and conquer strategy to maximize network bandwidth. Sorry to be dense but I could not find documanetation on how to access the o
