[Beowulf] using two separate networks for different data streams

  I've looked around, in the list and google and didn't find anything 
elucidating enough on this so mabe someone could englight me or point me 
where to look.

  I've seen architectures with two network switchs, one is used for I/O 
(writing, reading, so on) and another for message passing (MPI). how is 
this achieved? I get the idea, from one place, where the applications 
running must be aware of this but I was thinking that for this to work it 
must be transparent to the application. How can this be achieved?

  Any thought will be appreciated.

  best regards,

  Ricardo Reis
