The default Gaussian memory setting is set low to allow quick interactive tests of your input deck. The main resources to consider are memory, number of processors and scratch space which can be specified in various ways: see the equivalencies section in the Link 0 commands. If you are unsure of the resource requirements for your calculation refer to the Gaussian user guide's Efficiency Considerations. ^ "Comments on the "Banned by Gaussian" Website".Note that as the Gaussian program is made up of a myriad of methods and functionality there is no typical Gaussian jobscript and we strongly advise users to give careful thought to the resources needed for your system size (as measured by number of basis functions) and calculation type.^ "WATOC discussion on Computational Software"."Software company bans competitive users".
