What's wrong with that?

I am using non-blocking send and receive, and i want to calculate the time
it took for the communication.

You probably have to start by defining what you mean by "the time it
took for the communication".  Anyhow, the Peruse instrumentation in OMPI
might help.
Again, you should probably start by thinking more precisely about what time you want to measure.  E.g., ask yourself why the answer even matters.
