In the syntax of MPI_Recv and like API's of MPICH,the first parameter is buf
which is stated as OUT. I assumed that process executing MPI_Recv will receive
a POINTER to a buffer in the receiver address space. But under this assumption
the program does not work. If a supply a valid pointer to a msg structure
in the receiver address space the program works.
What seem sto be the problem?
