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.
