Gaussian 16 Linux -
Reviewing the features of Gaussian 16 is like reviewing the dictionary; it has everything.
If you need a specific quantum chemical method, G16 likely has it, and it is likely debugged to perfection.
In your input file, do not allocate all RAM (%Mem=64GB) if you run parallel jobs. The rule of thumb:
%Mem = (Total RAM / Number of cores) * 0.8 (leave 20% for OS overhead).
Gaussian 16 on Linux is a reliable workhorse for routine quantum chemistry – especially if your institution already has a license. Learn to write clean input files, manage scratch space, and debug common SCF failures. For new projects or GPU-accelerated workflows, consider ORCA 6. But for high-throughput calculations on CPU clusters with well-established methods, G16 is still a safe bet.
Pro tip: Use %CPU=0-31 to pin threads, set %mem=32GB, and always test with a small basis first (e.g., 6-31G(d)) before scaling up.
