Debugging parallel case
in my practical semester I'm working on an interface to connect a new linear equation solver framework to OpenFOAM. I want to solve the equation of A*x=b with another solver.
What I've done so far is to convert the matrix A, the right-hand-side vector b and the starting solution x to our own Matrix and Vector format. Solving works fine so far in serial, but now I try to use our solver in parallel cases. I need the data that is communicated between the processes.
Can anyone tell me, where and how the halo data of the processor boundaries is handled?
I tried to Debug a parallel case but don't manage to get it running. Did anyone of you ever debug a parallel OpenFOAM-case and can tell me how to do it. I already tried parallel debugging in eclipse with PTP and also tried Allinea DDT but none of them really worked.
I'd be very pleased, if someone just could give me a hint where to start searching.
