on the run flow-rate evaluation on a cluster

I've got a problem with coding a parallel calculation of the flow-rate which is to be evaluated on the run (not by integratePatchField).
My overall purpose is the following: I want the flow-rate to influence the inlet boundary conditions of an internal flow.
So far I've actually managed to evaluate the flow-rate, but it only works if I'm performing parallel calculations on my local machine or on one single node of a cluster. However if I try to run the very same calculation on a cluster distributed over several nodes, it always yields a zero flow-rate.
So obviously the problem must have something to do with parallelisation or with mpi ...
Finally here is the code, I added to the original icoFoam solver:
// Declaration and Initialisation of Variables
word outletPatchName = "OUTLET";
// search for label of the outlet patch by the name within the boundary dictionaryI'd be glad for any helpful comments.

I hope that helps!
