[Wien] configuring parallel options using ssh

[Luc Fruchter]

Dear users,

I failed configuring the parallel options to run cases on several 
machines, each of them with several CPUs, driven by ssh protocol.

* Configuring the parallel options with: shared memory, MPI = 0, ssh 
protocol, allows to run parallel jobs using several CPUs on the same 
machine. However, a .machines file with several machines will run using 
all required CPUs on the machine where launched (ignoring hosts).

- Configuring with: no shared memory, MPI = 0, ssh protocol, will run no 
parallel jobs, either on the same or different machines (Below is the 
output for the error in this case).

All machines communicate without problem with ssh and no password, and 
have identical file paths.

Thanks for helping
