Dear David and Michael and amber user
I re-try to run 4096wat the way the Michael and David say ,but I
couldn't run 4096wat .
And I got the same meesages.

And I tested the progran David said.
> mpicc test.c
> mpirun -np 2 a.out
So, I got the messages ....
Starting
Node 0 to 1: throughput 34.96 Mbytes/sec
Node 0 to 1: throughput 35.26 Mbytes/sec
Node 0 to 1: throughput 34.97 Mbytes/sec
Node 0 to 1: throughput 35.27 Mbytes/sec
Node 0 to 1: throughput 34.72 Mbytes/sec
I think that this messages are the speed of message passing.
The score is correct. Because I test the program on SMP Machine.
But I can't solve the problem of 4096wat.
Would you tell me any hint?
Thank you.
