 Could someone give me an estimate, or suggest how to do the estimate myself,
 for the amount of scratch space required for an MP2/6-31g* geometry optimisation
 on styrene ?  (C8H8,28 occupied mo's, 138 ao's) I am using G90 on RS6000.
 Any suggestions about the optimum way to go about such a calculation of this
 size would be welcomed.  I would guess this will take 3-5 days of cpu time.
 Many thanks in advance, and I will pass the comments back.
