Well, as I said, I'm not a lawyer and I'm not about to argue legal issues with you :-) All I can do is reiterate that the lawyers involved (a) felt that this was required as a gateway to providing commit permissions to our repository, (b) that it was separate from the license itself, and (c) th

I think the problem is that the MCA params need to be set at startup, along with the flag indicating where they came from, but also need to be changeable via the MPI_T interface at a later point. So we are tripping over the issues of when to release and replace the param values, ensuring they ar

I dug into this a bit and think the patch wasn't quite complete, so I modified the approach to ensure this race condition gets resolved in every scenario. Hopefully, r32643 takes care of it for you. On Aug 29, 2014, at 1:08 AM, Gilles Gouaillardet wrote: > Ralph and all, > > The following t

I was under impression that mca_tl_openib_tune_endpoint supposed to handle the miss-match between tunings of different devices. Few years ago we did some "extreme" inter-operability testing and ompi handled all cases really well. I'm not sure if I understand correctly what is the "core" issue.

Ralph, r32639 and r32642 fixes bugs that do exist in both trunk and v1.8, and they can be considered as independent of the issue that is discussed in this thread and the one you pointed. so imho, they should land v1.8 even if they do not fix the issue we are now discussing here Cheers, Gille
