i have a few questions about buffer management in MPI.
* What is the default amount of buffer allocated by a
system for MPI application?
* What happens when a send message size is more than
the buffer size allocated by the system?
* where does this memory reside?
* how do MPI_send and MPI_recv use this buffer?
* is there any difference between LAM implementation
and MPICH implementation of buffer management?
It would be very grateful if anyone can help.
Thanks,
regards,
Suren.
