Most universities run Gaussian 16 Linux on SLURM clusters. Here is an optimal SLURM script:
%NProcShared=8 %Link1=node1,node2,node3 #P B3LYP/6-31G(d) Opt Use code with caution.
The %chk= directive stores the checkpoint file, which holds wavefunction and geometry information and can be reused for subsequent calculations. The %mem directive sets the total memory available to Gaussian (in MB or GB). The %nprocshared directive specifies the number of OpenMP threads—this must match the number of cores allocated by your scheduler.
Intel or AMD x86_64 processors. Multicore processors are highly recommended for parallel execution.
If a Gaussian job terminates unexpectedly due to power loss or convergence errors, it leaves behind massive .rwfd files in your GAUSS_SCRDIR . Implement a daily cron job script to clean up orphaned temporary files older than a few days to protect your disk capacity. Managing Jobs via Slurm Workload Manager
It is best practice to install Gaussian in a global directory like /usr/local or a dedicated software partition.
Gaussian 16 is a commercial program with strict licensing:
sudo mount -t tmpfs -o size=30G tmpfs /mnt/ramdisk export GAUSS_SCRDIR=/mnt/ramdisk
# Gaussian 16 Configurations setenv g16root /usr/local setenv GAUSS_SCRDIR /scratch/$USER/g16 mkdir -p $GAUSS_SCRDIR source $g16root/g16/bsd/g16.login Use code with caution. The Importance of GAUSS_SCRDIR
