>The pure 64-bit firefly version is important for MCSCF calculations of big molecules (50-70 atoms), where the time-limiting phase becomes disk r/w operations.
Firefly incorporates very efficient MCSCF module and has dedicated
integral transformation code for large molecules.
See http://classic.chem.msu.su/gran/gamess/mcscf.html for details.
