Hello,

I have been working with a parallel abinit on an IBM p590 for a while. Since 
it is one machine with a bunch of processors, I just need to create a file 
machines with

localhost:4

to run a job on 4 processors. Then I start the job with 

mpirun -np 4 -machinefile machines abinip < job.files >& log

This is all working and I wanted to try this on a x86 cluster. Before I 
continue, let me say that the master can ssh to itself and all nodes without 
password prompt.
I installed mpich and abinit on the master and the directories are mirrored 
to all nodes. When I execute mpirun on the master with a machinefile of

master:4

I get the error message

master: Connection refused
p0_3193:  p4_error: Child process exited while making connection to remote 
process on master: 0 

written to the log file. With a machinefile of

node1:4

I get

Host address mismatch for 192.168.199.1
p0_3292:  p4_error: Child process exited while making connection to remote 
process on node1: 0

192.168.199.1 is not the ip of the host, I do not know how mpi gets the idea. 
Finally I tried to execute mpirun while being on node1 and got

Permission denied.
p0_28472:  p4_error: Child process exited while making connection to remote 
process on node1: 0


Hopefully one of you can give me a hint what to do to make it work.

Cheers,
Christian
