Molecular geometry is unstable or electronic structure is complex.
By default, Gaussian 16 uses a conservative amount of memory. For modern multi-core Linux systems, always override this setting.
2GB per core is a baseline; 4GB+ per core is ideal for large CCSD(T) or DFT calculations. 2. Installation Steps gaussian 16 linux

This guide provides a step-by-step walkthrough for installing, configuring, and optimizing Gaussian 16 on a Linux operating system. System Requirements and Prerequisites
%nosave
To execute Gaussian 16 from any terminal session, you must configure the environment variables. Update your shell configuration file depending on whether you use Bash or Csh. For Bash Users ( ~/.bashrc )
sudo groupadd g16 sudo chown -R root:g16 /usr/local/g16 sudo chmod -R 750 /usr/local/g16 Use code with caution. Add your authorized users to this newly created group: sudo usermod -aG g16 username Use code with caution. Step 3: Configure Environment Variables
Now go compute!
