All the information is on the web, under the mpi-3 ft working group. If you need a URL, I can send it to you later - don't have access now.

Hi, What is the telecon schedule and how does one get invited?

		For the next telecon I propose that we address the following topics.

	I agree with Greg - it would be great if we could pick this up
	again and try to come up with a single, common proposal. There is
	interest in this from multiple WGs (which is probably part of
	the problem of why nobody has pushed this forward) and if the FT
	group could continue to "host" this, that would be great. It
	would also be good to cross-post the TelCon announcement to the
	tools and AM WGs (for the latter, Torsten has voiced interest).

		- During the face-to-face discussion we began talking about the desired error notification semantics for collectives. The question is: are MPI implementations allowed to provide no error notification as part of their collectives, relying on calls to MPI_Validate for this functionality or do we expect them to report all relevant errors. In particular, is MPI_Barrier responsible for reporting failures of any members of the communicator or is it allowed to mis-behave in the event of failures and for example, return successfully even if one process failed before calling MPI_Barrier? If so, how do we bound the limit of such mis-behaviors?
