Maintaining accuracy while increasing number of processors

I need to know more about the PETSc parallel GMRES solver. Does the solver maintain the same accuracy independent of the number of processors. For example, if I subdivide a mesh with 1000 unkowns into 10, 100, 1000 processors should I expect to get always the same result? If no, why not? Are there any studies on this?

Thank you,
