Hi all,

I am trying to run a computation across several workstations using MPI.
I use the method MPI_Allgatherv to broadcast an Array<double,2> to the
processors.
This method takes a double* pointing to the data to share between the
processors.

Is there a way to obtain a pointer to the double in Array<double,2> to
avoid copying the data in a malloc'ed double* before calling MPI_Allgatherv.

Thanks a lot,

                        - Olivier
