I honestly don't rememb
yes i call MPI_init after MPI_finalise ,because i use mpi in function and i
call it lot of time .
thank you for ur help ,now i call mpi_init and finalize out of funtion and
it work .
thank you

Any particular reason these calls don't nest? In some other HPC-like
paradigms (e.g. VSIPL) such calls are allowed to nest (i.e. only the
finalize() that matches the first init() will destroy allocated
resources.)
Just a curiosity question, doesn't really concern me in any particular way.

Hi,
you could try the following (template):
MPI_Send( &vec[first_element], num_elements*sizeof(T), MPI_BYTE, ..)
MPI_Recv( &vec[first_element], num_elements*sizeof(T), MPI_BYTE, ..)
As far as I know STL vectors use contiguous memory for the values of the
vector.
However, I didn't test this and
Did you call MPI-INIT after you called MPI-finalize? If so, you're not allowed
to do that. Call. MPI-INIT once and call MPI-finalize once.

You might want to look at boost.mpi.
