# Options for Gaussian 03/09/16

#### Level of theory

Any combination of computational method and basis set can be used.

#### Memory and number of processors

In GRRM17 program, you can use GauMem and GauProc options to set the amount of memory (%Mem=nMW in Gaussian) and number of processors (%NProc=n in Gaussian) for a Gaussian job. For example, the memory (%Mem=30MW) and the number of processors (%NProc=2) used in a Gaussian job can be set as:

0 1
C         -0.000000000711          0.000000000452         -0.533622543616
O          0.000000000233          0.000000000201          0.679217381431
H          0.000000000239          0.942015259527         -1.124391918573
H          0.000000000239         -0.942015260180         -1.124391919242
Options
GauMEM = 30
GauProc = 2
