Gaussian 16 Linux ((full))

| Component | Recommended Specification | Notes | | :--- | :--- | :--- | | | ~2-3 GB (executables) + 200 GB+ (scratch) | The program files require 2-3 GB. For large jobs, especially post-SCF calculations like MP2 or CCSD, temporary scratch space of up to 200 GB or more is essential. | | Memory (RAM) | 256 GB or higher | While the default memory allocation in Gaussian is 800 MB, computational nodes for production runs often feature 256 GB or more to handle large systems. | | Swap Space | 1-2 GB | This is in addition to physical RAM. | | CPU | Modern x86_64 with AVX2 support | For optimal performance, CPUs that support the AVX2 instruction set (e.g., Intel Haswell or newer) are highly recommended. |
