Hi Fernando,

Is "Boussines" the name of your computer? You may have two versions of MPI in your computer. This may happen, for instance, if you compiled your own version of MPI, and your system already has an MPI installed. Could you please share the exact command-line arguments you're using both for your cpi example which worked, and for that which didn't work.

In addition, this previous discussion may help:

HI, my name is Fernando. I'm trying to execute a model in my pc. Mpich2 is already installed and running (I executed the cpi example with success).

However when I try to execute my program I get the following error: Aborting: unable to connect to Boussines, smpd version mismatch
