Gentlemen
I am struggling to get MPI working when the hostfile contains different nodes.
I get the error below. Any ideas ?? I can ssh without password between the two
nodes. I am running 1.2.8 MPI on both machines.
Any help most appreciated !
MPITEST/v8_mpi_test> mpiexec -n 2 --debug-da
OK, I installed 1.4.4, rebuilt the exec and guess what .. I now get some
weird errors as below:
mca: base: component_find: unable to open
/usr/local/lib/openmpi/mca_ras_dash_host
along with a few other files
even though the .so / .la files are all there !

You need to clean out the old attempt - that is a stale file

My mistake Ralph, should have done a make uninstall instead !
Thanks

I had
fully uninstall the disto-installed version of Open MPI on all the nodes (e.g., Red Hat may have installed a
different version of Open MPI, and that version is being found in your $PATH before your custom-installedversion).

Jeff,
I wiped out all versions of openmpi on all the nodes including the distro
installed version.
I reinstalled version 1.4.4 on all nodes.
I now get the error that libopen-rte.so.0 cannot be found when running mpiexec
acros
nts, or conditional blocks that are only invoked during
interactive logins, for example.

In trying to debug an MPI_Waitall hang on a remote
node, I created a simple code to test.
If we run the simple code below on 2 nodes on a local
machine, we send the number 1 and receive number 1 back.
If we run the same code on a local node and a remote node,
we send number 1 but get 32767 back.
I had exactly the same problem.
Trying to run mpi between 2 separate machines, with each machine having
2 ethernet ports, causes really weird behaviour on the most basic code.
I had to disable one of the ethernet ports on each of the machines
and it worked just fine after that. No idea why though !

Did you have both of the ethernet ports on the same subnet, or were they on
different subnets?
