WebJun 12, 2024 · For DFT methods, Gaussian will scale well up to 16 cores, with diminishing returns (or even losses!) past this point. Memory allocations will depend on the size of your molecules. Large systems or systems that contain heavy atoms (more electrons) will require more memory. 256-1024 MB per CPU is generally the optimal range. Note that using too ...
