If you are a computational chemist, the phrase "segmentation fault" triggers a specific kind of PTSD. For years, running Gaussian on Windows was the default for many students, but ask any high-throughput researcher: Linux is the native habitat of Gaussian 16.
Yes, the learning curve for bash is steeper than clicking a .exe . But once you learn to chain jobs with ; , run background processes with & , and monitor htop , you will never go back.
This usually means your shell limits are too low. Linux has a hard limit on "Max user processes."
Whether you are setting up a local workstation (like an AMD Threadripper + 4090 build) or logging into a university HPC cluster, running G16 on Linux isn't just faster—it unlocks the full potential of the software.
