Linux: Gaussian 16

# Extract to /opt or /home tar -xjvf G16_AVX2.tbz -C /opt/ chmod -R 750 /opt/g16 The critical part: Environment Variables echo 'export g16root=/opt' >> ~/.bashrc echo 'export GAUSS_SCRDIR=/scratch/$USER' >> ~/.bashrc echo 'source /opt/g16/bsd/g16.profile' >> ~/.bashrc

Here is your no-fluff guide to installing, optimizing, and debugging Gaussian 16 on a Linux environment (CentOS/RHEL/Ubuntu). Unlike modern software, Gaussian 16 doesn't come with a pretty ./configure script. It comes as a tarball (usually G16_AVX2.tbz ). The installation is essentially extraction and declaration .

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. # Extract to /opt or /home tar -xjvf G16_AVX2

cd /opt/g16 ln -sf g16_avx2 g16 Linux handles I/O differently than Windows. Gaussian’s algorithm relies heavily on reading/writing to disk. If you use a standard SATA SSD, your expensive CPU will spend 80% of its time waiting. The installation is essentially extraction and declaration
