We had to remove the support for DMLocalToGlobalBegin/End() for this case since it was too difficult to maintain.
Why are you using DMLocalToGlobalBegin/End() here? All it does it discard the ghost values. Instead of putting values into the wb0_gfpp_loc and then calling DMLocalToGlobalBegin to move the values into wb0_gfpp you should just put the values directly into wb0_gfpp and never even have a wb0_gfpp_loc Note that if you use DMDAVecGetArray() on wb0_gfpp_loc you can use it also on wb0_gfpp instead.
