Try lowering the eager threshold more gradually... e.g., 4K, 2K, 1K,
512, etc. -- and watch what happens. I think you will see what you
expect, except once you get too small then the value is ignored
entirely. So, the setting just won't work at the extreme value (0) you
want.
Maybe the thin
Dear all,
I am trying to disable the eager mode in OpenMPI 1.3.3 and I don't see a
real difference between the timings.
I would like to execute a ping (rank 0 sends a message to rank 1) and to
measure the duration of the MPI_Send on rank 0 and the duration of
MPI_Recv on rank 1. I have the fol
