Hi,
Just out of curiosity - what happens when you add the following MCA option to
your openib runs?
-mca btl_openib_flags 305
Thanks,

You Sir found the magic combination.
I verified this lets IMB and CRASH progress pass their lock

Hi all,
I hope to provide enough information to make my problem clear. I
have been debugging a lot after continually getting a segfault
in my program, but then I decided to try and run it on another
node, and it didn't segfault! The program which causes this
strange behaviour can be downloaded wit
Ralph,
I have the same issue and I've been searching how to do this, but I couldn't
find.
What exactly must be the string in the host info key to do what Rodrigo
described?

Hi Ralph,
We've had a number of user complaints about this. Since it seems on
the face of it that it is a debugger issue, it may have not made it's
way back here. Is your objection that the patch basically aborts if it
gets a bad value? I could understand that being a concern. Of

You need to use MPI_Comm_spawn_multiple. Despite the name, it results in a
single communicator being created by a single launch - it just allows you to
specify multiple applications to run.
In this case, we use the same app, but give each element a different "host"
info key to get the behavior

Hmmm? We're not removing the putenv() calls. Just adding a strdup()
beforehand, and then calling putenv() with the string duplicated from
env[j]. Of course, if the strdup fails, then we bail out.
As for why it's suddenly a problem, I'm not quite as certain. The
problem we do show is a dou
Guess I'm having trouble reading your diff...different notation than I'm used
to seeing. I'll have to parse thru it when I have more time.

Ralph, thank you the reply.
I just try what you said and it works! I didn't think to try the array of
info arguments because in the spawn_multiple documentation I read the
follow:
"... *array_of_info*, is an array of *info *arguments; however, *only the
first argument in that array is used. Any s
