[OMPI users] Object Send Doubt

[Carlos Henrique da Silva Santos]

Dear,

  I m looking for a solution.
  I m developing a C++ code and I have an object called Field. I need
to send/recv this object over some process allowed in my cluster. For
example, I have to send Field from process 1 to process 2 and 3, but
not process 4.
  My questions are:
  Is possible to send an object by Open-MPI?
  If it yes, could you send me an source code example to do it or reference ?

Thank you.

Carlos
