[mpich-discuss] MPICH2 on LAN with Ubuntu 12.04

[dave]

Hello Group,

Is the following statement option -F still correct?

dave at ubuntu-desk:/home/mpiuser/cloud$ sudo mpiexec -f hosts.cfg -n 4 ./hello
[sudo] password for dave:
--------------------------------------------------------------------------
mpiexec was unable to launch the specified application as it could not 
find an executable:

Executable: -f
Node: ubuntu-desk

while attempting to start process rank 0.
==================================

I tried it another way too with same result:

dave at ubuntu-desk:/home/mpiuser/cloud$ sudo mpiexec -n 8 machinefile ./hello
--------------------------------------------------------------------------
mpiexec noticed that the job aborted, but has no info as to the process
that caused that situation.
--------------------------------------------------------------------------

Machine file, two lines, one for each machine in the network. Each with 
SSH and mpich2:

ubuntu-desk-2:2    #
ubuntu-desk    #


--------------------------------------------------------------------------

Any ideas about mpiexec statement or anything else to get these machines 
talking?

Dave
