Using PCM for single point SCF on larger systems



Hi,
 I'm trying run single point SCF calculations on an atomic systems of
 between 70 and 100 atoms.
 Has anyone out there got experience of using PCM on large systems? What
 dimensions are optimal in GAMESS for such runs - i.e. what should I set
 MXSP and MXTS to?
