A built-in text editor lets users quickly modify keywords, memory allocations ( %mem ), processor counts ( %nprocshared ), and molecular coordinates without leaving the application. Each GPU must be controlled by a specific CPU core
Gaussian 16W operates using input files (usually ending in .gjf or .com ). These files contain "keywords" that tell the software what math to run. Standard Job Types memory allocations ( %mem )
For users requiring accelerated calculations, Gaussian 16 supports for Hartree‑Fock and DFT calculations — but only under Linux . GPU support is not currently available in the Windows version of Gaussian 16. Supported GPU models include NVIDIA K40, K80, P100, and V100 with at least 12 GB of memory. Each GPU must be controlled by a specific CPU core.
Build the molecular structure and use GaussView to generate a .gjf input file.
