These instructions don't include any queueing software, so to submit a job open a terminal and type type g16 inputfilename.com
Here are the steps to do it.
1) Get a xeon computer (as of 11/9/2017 I have not tried it on other CPU architectures)
2) install Suse Linux (Leap 42.3) on it https://software.opensuse.org/distributions/leap (as of 11/9/2017 I have not tried other linux distributions)
3) copy g16.tar.gz to /usr/local on your computer
4) uncompress g16.tar.bz by typing as root tar -zxvf g16.tar.gz
5) After uncompressing change the group on the g16 folder so everyone can use the files by typing chgrp -R users g16
6) create a scratch directory for Gaussian (note: I put it in home but feel free to put it anywhere you have a lot of free space)
7) each users will need to create a file in their home directory called .bash_profile and put in the following lines (again if you put your scratch directory somehwere else then make the appropriate changes in line two below)
