Can you clarify a bit more? Is that a fatal failure at that point? Or is it more like MPI_Alloc_mem failing where I can retry later or just do a regular malloc (in this case, a regular MPI_RECV). -- Pavan On 08/26/2013 10:19 AM, David Goodell (dgoodell) wrote:

I'd say that's implementation defined behavior, no different than hitting any other system resource limitation right now.

Jeff,

This should probably be moved to the point-to-point WG, but I'll comment on this thread for now.

Such a proposal was brought up at the very early stage of the MPI-2.1 process (I don't remember by whom). The main concern at that point was what happens when the memory allocation fails. Will the receive fail? What happens to the sent message?

Can you work these details into your slides?

Dave Goodell and I have a proposal that we've socialized a bit around with other Forum members, and would now like larger Forum feedback. I'll be presenting the attached slides on the concept of an "allocate receive" in Madrid (3:30-4pm on Thursday).

There's no text or ticket yet; this is an idea that we want to get feedback on before working up a full proposal.
