Hi!
Can anyone tell me how I can synchronize the clocks of
the machines running an MPI program?
(I know it has something to do with MPI_WTIME_IS_GLOBAL)

I need to get the times commands start and return. I need these
times to be the same for all processor so that I can compare them.
This is what profiling tools (like Vampir, jumpshot, Pablo etc) do,
but I want to create something for my own needs.

please email me.

Andreas.
