There was a paper from a while back where a group implemented TIPC for OMPI 1.0.2 and showed some decent improvement. It was pretty well done in terms of what they measured but the over-all gains were of the order of 3-4% improvement for "real world" applications. http://www.fz-juelich.de/nic-s

I am personally unaware of anyone working TIPC support for Open MPI -- but that doesn't mean it isn't happening. I took a *brief* look at the TIPC web site -- it is sorta analogous to Open-MX? (i.e., sending raw ethernet frames as opposed to TCP) We'd love to see a BTL module for TIPC in Open

Hi, I'm wondering if anyone has looked at adding support in MPI for TIPC, Transparent Inter-Process Communication protocol? Considering TIPC's properties this should provide better performance than TCP on ethernet. Thanks for any info, Nils Carlson
