maximum size

Hi,I was wondering which is the maximum size of a data structure that can be send via MPI_Ssend or MPI_Broadcast. I suppose it's implementation dependent. If so, which factors determine it?thanks in advance,

Hi Joe,

It seems to me that internal implementation of MPI functions may limit the maximum size of a structure which can be transferred at once. But I think that it should not be less than 2GB. You can write a small test case and check this limitation.

Regards!
Dmitry
