Dear Paolo,

Thank you very much for your response.
As I understaood, if the number of pools and/or the number of processors in 
the pools reduces (somehow) from what the program has read from the command 
line, the program certainly stops. So, something should be wrong in the 
mpich2 response to the "mpdtrace" command.
Bests,
