Hi,
I am working on a n-body simulation which uses a lot of MPI_Bcast.
I am using -np 2 for the runs.
When i timed the MPI_Bcast for every iteration, I have this scenario coming up.
>From iterations 0 - 34, the time is 0.08 seconds for each MPI_Bcast and
somewhere in the range of 34 - 38, the time is reducing to 0.04 seconds for 1
iteration and then reducing to 0.001 for the rest of the iterations.
Is this any optimization in LAM-MPI.
Can anyone explain how MPI_Bcast is implemented in LAM-MPI.
thanks
Siva
