I will leave it to you to decide. I am sure I will be very pressed for time... On Sat, 11 Feb 2012, Fab Tillier wrote:

I think it would make more sense to fix the text for the WAIT and TEST routines, rather than spread the information around. The generalized request section might not need changes if we do this.

I don't know if I'll have time to put the text together before the meeting, though.

I am fine with the decision to make it the chapter committee responsibility. I suppose that means I need to draft text for the generalized requests?

It looks like this is a result of adding new request types without revisiting the original text. Under generalized requests, there is text that seems to imply that the request is set to MPI_REQUEST_NULL on completion, but it isn't explicit and should be.

This is a chapter committee correction.

Hi Folks,

Looking at the text for MPI_WAIT (page 54, line 15) and MPI_TEST (page 55, line 7), it seems to imply that the request handle is only set to MPI_REQUEST_NULL for non-blocking send and receive requests. Are generalized, I/O, and NBC requests not completed the same way? Are users required to free such requests explicitly after they complete using MPI_REQUEST_FREE?

I would have expected that all request handles except those to persistent requests are set to MPI_REQUEST_NULL, and persistent request just rather marked inactive. If that is indeed the intent, shouldn't we update the text to reflect this? Is this a ticket-0 level change?

Thanks, -Fab
