MPI - Running parallel on windows

Dear all,

Has anyone tried running the delft flow executable in parallel using MPI mpich2 on windows?
I have run the example provided on a computer server with 12 CPUs and 24 cores and it worked well. But when I run my own flow(3d) model, it does not speed-up so much.
Does anybody know why?How many CPUs and cores should I use in order to achieve the optimal computation?Should I rebuild and recompile the open source to get the MPI running version of Delft3D?

Thanks in advance
Li Haijun
