Developers,
I was about to test 1.3.3rc2, then I saw that 1.3.3 had also escaped. I
tried it, and voila! It solves the issue I reported in May, below.
Thanks for all the work that went into this.

Hi Bryan
I have seen similar issues on LANL clusters when message sizes were
fairly large. How big are your buffers when you call Allreduce? Can
you send us your Allreduce call params (e.g., the reduce operation,
datatype, num elements)?

Another user reports something somewhat similar at
http://www.open-mpi.org/community/lists/users/2009/04/9154.php . That

using?
OMPI was built with gcc v4.3.0, which is what's packaged with Fedora 9.

Since my demonstrator is somewhat large and cumbersome, I'd like to

Developers,
This is my first post to the openmpi developers list. I think I've run
