GAUSSIAN is commercial software, available from GAUSSIAN.INC.
GAUSSIAN is electronic structure programs. It is designed to model a broad range of molecular systems under a variety of conditions, performing its computations starting from the basic laws of quantum mechanics.
First, make a directory in your home directory, then go to the directory to create your input files and run GAUSSAIN94 from there.
To set the appropriate environment variables by typing:
source /projects/GAUSSIAN/gauss_init
or you could enter the above command in the .cshrc file in your home directory.
There are two ways to run GAUSSIAN94:
A batch submission script, batch94, is available. This sets an appropriate priority for jobs over three minutes and allows the user to logoff or continue with something else while calculating.
batch94 $GAUSS_TESTDIR/test013
It reads $GAUSS_TESTDIR/test013.com as input and produces output file test013.output in the directory from which batch94 is invoked (this must be a directory where you have write permission). Don't worry about "job disappeared can't start" messages; will attempt to fix. Do a "top" to see if job completed.
In your home directory, type:
g94 $GAUSS_TESTDIR/H2O.com ~/H2O
The output will be saved in file ~/H2O.log.
The ~ notation is shorthand for your home directory.
Be sure to use an uppercase O(ohh) not a 0(zero) in H2O
