[MPICH] Sending, receiving and braodcasting a user defined C++ class

[Yann Golanski]

I'm looking for advice here and hopefully this could be included into
an FAQ or whatnot. 

The attached code move data from a class in processor 0 to all the
other in such a way as said data ends up in the same type of class at
the end.  

My questions are:
  1- Is there a better way of doing this?
  2- How can my code be optimised?
  3- Any other comments?

Thanks.
