What version of knem and Linux are you using?

problem "fixed" by adding the --mca btl_sm_use_knem 0 option (with -npernode
11), so I proceeded to bump up -npernode to 12:
$ ../openmpi_devel/bin/mpirun -hostfile hostfiles/hostfile.wgsgX -npernode
12 --mca btl_sm_use_knem 0 ./bin/mpi_test
and the same error occurs,

In your first mail, you mentioned that you are testing the new knem support.
Can you try disabling knem and see if that fixes the problem? (i.e., run with
--mca btl_sm_use_knem 0") If it fixes the issue, that might mean we have a
knem-based bug.

Hi,
sorry for the confusion, that was indeed the trunk version of things I was

Hi All,
I am new to openmpi and have encountered an issue using pre-release 1.5rc5,
for a simple mpi code (see attached). In this test, nodes 1 to n sends out
a random number to node 0, node 0 sums all numbers received.
This code works fine on 1 machine with any number of nodes, and on 3
machines
