Dictates how many CPU threads Gaussian will utilize on a single node. Managing Scratch Files
This yields incredible I/O speeds but consumes physical RAM. gaussian 16 linux
Intel or AMD x86_64 processors. Multicore processors are highly recommended for parallel execution.
To run a job across multiple cores on a single machine, use the %NProcShared directive in your input file ( .gjf or .com ): %NProcShared=16 %Mem=32GB #P B3LYP/6-31G(d) Opt Use code with caution. Usually means GAUSS_SCRDIR is full or permissions are wrong
Fast scratch space is critical. Use local NVMe SSDs rather than network-attached storage (NAS) to prevent I/O bottlenecks. Software Dependencies
