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 boost.mpi may be the safest solution.
