maximum size

[Jose_Gordillo]

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!
