Gaussian 16 Rev. C.01 is now available on RNC.
All Gaussian 16 jobs shall be submitted through the PBS job scheduler to the queues. You can submit serial, shared-memory parallel, and Linda parallel jobs to different queues.
Before submitting a job users has to set an environment path at their account to get access to all g16 executables and your account has to be added to the Gaussian group. Please submit a request on the Helpdesk portal with your computational ID for adding your account to the g16 group.

Environmental set up to use Gaussian16:
Gaussian 16 is installed in the directory /apps/GAU16/avx2/g16. The Gaussian 16 system includes paths and initialization files to set up the user environment for running the program.
To set the path of g16 for your account follow the below steps:
- For Csh users run the following command, it will source g16setup.csh file and set the paths for the g16root and GAUSS_SCRDIR
$ source /apps/GAU16/avx2/g16setup.csh
- For Bash users run the following command, it will source g16setup.sh file and set the paths for the g16root and GAUSS_SCRDIR
$ source /apps/GAU16/avx2/g16setup.sh
Files in /localscratch/<userID> older than 7 days are removed automatically
- Using ssh for multi-node jobs
Gaussian 16 multi-node jobs use Linda libraries.Linda by default uses ‘rsh’ to communicate across multiple nodes. However the RN cluster is only enabled with ‘ssh’ for communication. To use Linda with ‘ssh’ please include the following directive in your job scripts:
setenv GAUSS_LFLAGS ‘-opt “Tsnet.Node.lindarsharg: ssh”‘
export GAUSS_LFLAGS =’-opt “Tsnet.Node.lindarsharg: ssh”‘
