Dmitry:
It turns out that by default in Open MPI 1.7, configure enables warnings for
deprecated MPI functionality. In Open MPI 1.6, these warnings were disabled by
default.
That explains why you would not see this issue in the earlier versions of Open
MPI.
I assume that gcc must have added su
So I configured and compiled a simple MPI program.
Now the issue is when I try to do the same thing on my computer on a
corporate network, I get this error:

Both.
To be specific: there's two layers

I'm not sure what you mean by "blocked"

Yeah, definitely. Thank you, Jeff.

Then I think Rolf (from Nvidia) should figure this out; I don't have access to
nvcc. :-)

Thank you for your answers. I've tried that but it doesn't seem to work.
The latest command I've issued is
# $HOME/aplic/openmpi/1.6/bin/mpirun -np 1 -host
localhost ./init_barrier_fini : -x
LD_LIBRARY_PATH=/home/Computational/harald/aplic/openmpi/1.6/lib
-prefix /home/Computational/harald/aplic
No, I'm configuring with gcc, and for openmpi-1.6 it works with nvcc
without a problem.
Actually, nvcc always meant to be more or less compatible with gcc, as far
as I know. I'm guessing in case of trunk nvcc is the source of the issue.
And with ./configure CC=nvcc etc. it won't build:
/home/d
Did you configure and build Open MPI with nvcc?
I ask because Open MPI should auto-detect whether the underlying compiler can
handle a message argument with the deprecated directive or not.
You should be able to build Open MPI with:
./configure CC=nvcc etc.
make clean all install

I believe you could resolve this by specifying the interfaces to use in the
order you want them checked. In other words, you might try this:
-mca btl_tcp_if_include eth1,eth0
where eth1 is the NIC connecting the internal subnet in the cloud, and eth0 is
the NIC connecting them to the Internet.
One further point that I missed in my earlier note: if you are starting the
parent as a singleton, then you are fooling yourself about the "without mpirun"
comment. A singleton immediately starts a local daemon to act as mpirun so that
comm_spawn will work. Otherwise, there is no way to launch t
You might also want to set up your shell startup files on each machine to
reflect the proper PATH and LD_LIBRARY_PATH. E.g., if you have a different
.bashrc on each machine, just have it set PATH and LD_LIBARY_PATH properly *for
that machine*.
To be clear: it's usually easiest to install OMPI
Try adding "-x LD_LIBRARY_PATH=" to your mpirun cmd line

Up to now, I've configured and installed OpenMPI 1.6 in my two systems
