Hi justa tester tester
Is your p2p1 interface an Infiniband port, or is it Ethernet?
If it is Ethernet, try removing "--mca btl_openib_if_include p2p1"
from your mpiexec command line, because it would conflict with
the other mca parameter you chose "--mca btl openib,sm,self".
Simpler may be bett
I see you are running this via "sudo". Unfortunately, that has a peculiar
behavior - it resets the environmental variables to something appropriate for
root. So I suspect that the library path is not correct as far as mpirun is
concerned.
You can check it easily enough - just do "sudo printenv"

You'll need to be a bit more specific. What describe should work fine.

This error typically occurs when the received message is bigger than the
specified buffer size. You need to narrow your code down to offending
receive command to see if this is indeed the case.

Thank you Ralph,
I found the problem. it is because I wrongly configured the second node's
selinux property (which is set to be enforced).
After it is disabled, the parallel-hello works fine.

Hi Andria
The problem is a permissions one - your system has been setup so that
only root has permission to open a TCP socket. I don't know what
system you are running - you might want to talk to your system admin
or someone knowledgeable on that operating system to ask them how to
revise

Hi Prakash
I can't really test this solution as the Torque dynamic host allocator
appears to be something you are adding to that system (so it isn't part of
the released code). However, the attached code should cleanly add any nodes
to any existing allocation known to OpenRTE.

There are no limits to launching on nodes in a hostfile - they are all

Hello,
Thanks for the patch. I still do not know the internals of Open MPI, so can't
test this right away. But here is another test I ran and that failed too.
I have now removed Torque from the equation. I am NOT requesting nodes through
Torque. I SSH to a compute node and start up the code as
No offense, but I would definitely advise against that path. There are
other, much simpler solutions to dynamically add hosts.
We *do* allow dynamic allocation changes - you just have to know how to do
them. Nobody asked before... ;-) Future variations will include an even
simpler, single API sol

Thanks for the info, Ralph. It is as I thought, but was hoping wouldn't
be that way.
I am requesting more nodes from the resource manager from inside of my

The runtime underneath Open MPI (called OpenRTE) will not allow you to spawn
processes on nodes outside of your allocation. This is for several reasons,
but primarily because (a) we only know about the nodes that were allocated,
so we have no idea how to spawn a process anywhere else, and (b) most

It looks like MPI processes were unable to connect back to the

port blocking running in your cluster?
