I've viewed this as a source-code requirement - Applications require no changes in their source code. That permits requiring recompilation. Bill On Apr 3, 2009, at 1:06 PM, Jeff Squyres wrote:
This is worth raising to the list.
What is the rule for 2.2 -- that existing MPI applications must be able to run with no changes against an MPI-2.2 library? Or is it that existing MPI applications must be able to compile and run with no source code changes against an MPI-2.2 implementation?
I hope it's the latter; this change is relatively important.

Aren't we changing C++ ABI herewith? If so, we may want to postpone this change till MPI-3.
