Ashly still having trouble using padb with openmpi/1.4.2

Ah ok, I put it there just because the user couldn't read that from my home
space, and never even thought of that. gahhh.
Thanks,
BTW I tried joining the padb mailing list.

Hi,
I am getting interested in this thread.
I'm looking for some solutions, where I can redirect a task/message (MPI_send)
to a particular process (say rank 1), which is in a queue (at rank 1) to
another process (say rank 2), if the queue is longer at rank 1.
How can I do it?
First of all, I
padb as a binary (it's a perl script) needs to exist on all nodes as it calls
orterun on itself, try installing it to a shared directory or copying padb to
/tmp on every node.
To access the message queues padb needs a compiled helper program which is
installed in $PREFIX/lib so I would recomme
We have ddt, but we do not have licenses to attach to the number of cores these
jobs run at.
I tried padb, but it fails,
Example:
ssh to root node for running MPI job:
/tmp/padb -Q -a
