Firstly, they will not influence runs with PUGH in any way.
Meta mode means "run this function only once, even if there are several
convergence levels present". For example, a routine that performs a
convergence test is scheduled in meta mode.
Singlemap mode means "run this function once per refinemen level and per
map". A map is a coordinate system; a multi-map simulation is what
could also be called a multi-patch simultion in multigrid. For
example, a routine that needs access to grid point indices
(hyperslabbing) needs to be scheduled in singlemap mode. A routine
that interpolates within a refinement level or wants to synchronise
still needs to be scheduled in level mode.
I don't think that we have found the final set of modes yet. They might
change again in the future.
