Open MPI have support for one parallel debugger: Total View. I don't
know how DDT interact with the MPI library in order to get access to
the message queues, but we provide a library which allow tv to get
access to the internal representation of the message queues in Open
MPI. The access to the message queue in complete, you can see all
pending sends, receives as well as unexpected messages.
Thanks,
george.

starting to do some work with parallel debuggers (ddt to be exact)
and was wondering what the time line for message queue debugging
was. Just curious! Thanks.

Hi Brock
This question has just become "frequently asked" -- no-one asked
in all
of the last 12 months, and I think you're the third person this
month,
the second today!
OpenMPI does not (yet?) support message queue debugging - this means
the interface just isn't there for a debugger to get the information,
sadly. Open-MPI's own FAQ does mention this lack of support, but I'm
not sure of an ETA or whether they are actively developing it.
Best wishes
David

Hello,
According the the manual if you get the message "unable to load
message queue library" to look at the FAQ, but i can not find a faq
anyplace. We are new users and our mpi lib is openmpi-1.0.2
