[OMPI users] error running mpirun command

[Eric F. Alemany via users]

Hello everyone,

I am new to Open MPI please forgive me for my beginner mistake. I read through 
the FAQ of open-mpi.org website and built a small cluster 
(9 nodes - including a master node).
I thought i followed the instructions accordingly but i am having issue running 
a simple mpirun.

$ mpirun -np 84  - -hostfile hostsfile ./openmpi_hello.c

mpirun: Forwarding signal 20 to job
--
ORTE does not know how to route a message to the specified daemon
located on the indicated node:

  my node:   phaser-manager
  target node:  radonc-phaser01

This is usually an internal programming error that should be
reported to the developers. In the meantime, a workaround may
be to set the MCA param routed=direct on the command line or
in your environment. We apologize for the problem.

I dont understand the meaning of the error message. I can share more of my 
configuration files if someone would be interested in helping me.

Thank you in advance for your help.


Best,
Eric

Eric,

which version of Open MPI are you using ? how many hosts in your hostsfile ?

The error message suggests this could be a bug within Open MPI, and a
potential workaround for you would be to try
mpirun -np 84  - -hostfile hostsfile --mca routed direct ./openmpi_hello.c

You might also want to double check all your hosts can access each
other with TCP/IP and on all ports (e.g. no firewall should be
running)

Cheers,

Gilles
