Re: [OMPI devel] trunk hangs since r19010

[George Bosilca]

I ran few tests and the only combination leading to a deadlock is openib and self. As openib is the only BTL supporting self communications (except self of course), I guess it interfere with self in some more or less strange ways. I didn't had the time to dig deeper yet to see what exactly happens there, I'll schedule this later today.

This used to be true, but I think we changed it a while ago (Pasha: do you remember?) because Mellanox HCAs are capable of send-to-self (process) and there were no code changes necessary to enable it. So it allowed a slightly simpler command line. This was quite a while ago, IIRC.

Yep, Correct.

FYI. In my MTT testing I also see a lot of killed tests.
