Often caused by insufficient memory or stack size limits. Try running ulimit -s unlimited before starting the job.

Charge, multiplicity, and coordinates. 4. Optimizing Performance on Linux

Ensure you have source d the g16.profile . gaussian 16 linux

Note: Always point GAUSS_SCRDIR to a fast, local drive with plenty of space. 3. Running Your First Calculation

export g16root=/opt source $g16root/g16/bsd/g16.profile export GAUSS_SCRDIR=/scratch/user_name Use code with caution. Often caused by insufficient memory or stack size limits

If you are on a cluster, never run g16 directly on the login node. Use a submission script:

Ensure the group ownership is set correctly so authorized users can run the binaries: chown -R root:g16 g16 chmod -R 750 g16 Use code with caution. Step 3: Configure the Environment local drive with plenty of space.

Gaussian 16 on Linux is a powerhouse for molecular modeling. By correctly configuring your environment and managing your scratch space, you can significantly reduce calculation times and improve reliability.

Match %NProcShared to the number of physical cores available.

Use rm commands in your job scripts to delete .rwf and .chk files if they aren't needed for restart. Using Slurm or PBS
