Saving data from MeshFunction CPU MPI doesn't work for bigger dimension
MeshFunctionPointer 3D on CPU with MpiIO doesn't save the right data for big mesh (256^3). Everything works on CPU for meshes 16^3,32^3,...,128^3. Calculation is fine and saved data are the same as the program (hamilton-jacobi branch) calculates. Only the biggest mesh I use is making me troubles. Those values of 256^3 calculation are fine when I see them in console but those values doesn't save into file. The MPI devides the original mesh by default in "z" direction and I use 4 processes for calculation (2 cores on laptop).
Both calculation and saving values works on GPU with and without MPI!
