[MPICH] bsend behavior differences

[Vlad Branzoi]

Hi,

I have a question about the behavior of buffered send on different machines.
On one machine MPI seems to send stuff from the buffer on a consistent basis
while on another machine it only sends messages out when I 'flush' the
buffer via a buffer_detach and buffer_attach.  What could be causing this
different behavior, and is there a way to make it consistent.

Both machines are running MPICH2 1.0.6p1.  The first one is running WinXP
32-bit version and the 2nd machine is running WinXP 64-bit version, however
both are running the 32-bit version of MPICH2.

Thanks,
Vlad
