I've been writing a solver based off interFoam that does something like

forAll(gamma,cellI){
-get neighbouring cell values
-do stuff with them
}

which works in serial and I am now trying to parallelize it. I'd like to let each processor access a buffer of cell values across the processor boundary. I know that what I need is buried somewhere in Pstream but I haven't been able to find it. Can anyone please help me out or point me toward example code?
