Dear Dick,

Thank you. I remember we exchanged a couple of emails about the possible extensions to the set of assertions, like one-sided and I/O, and in my recollection, almost reached an agreement that this can improve performance and possibly memory footprint, as well as be expressed thru assertions. Do you still feel favorable about this?

Best regards.

Alexander

Hello to the Subset WG

I appreciate the interest in my proposal for Init time assertions. Unfortunately I will not be able to come to the next Forum meeting to discuss face to face.

I did write up a fairly detailed draft a few weeks back and post it on the MPI 2.2 Wiki at: http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/InitTimeAssertions

Maybe that will help clarify what I have in mind. My proposal does not include "hints" so I did not discuss the definition of a hint. I did try to be firm about the meaning of an assertion.
