This appears to be similar to the problem described in:
https://svn.open-mpi.org/trac/ompi/ticket/2043
However, those fixes do not work for me.
I am running on an - i5 sandy bridge under Ubuntu 10.10 8 G RAM
- Kernel 2.6.32.14 with OpenVZ tweaks
- OpenMPI V 1.4.1
I am trying to migrate existing software to a new cluster (A,B)
Symptoms:
I can run the ring demo on a single machine, either A or B
with any number of processes.
But when I combine the 2 machines I am limited to 2 processes,
any more and MPI hangs. It gets as far as: Process 0 sending 10 to 1,
tag 201 (3 processes in ring) Process 0 sent to 1and there it stays...
Any help greatly appreciated.
