since MPI is a low level parallel programming library, a way to handle
linked objects easily is to pack them into arrays before send
operations. after the receipts, the linked objects are rebuilt from the
receive buffer.
more generally, this method consists in considering send and receive
buffers as binary files in which data is stored.
i hope this will help you.
