Gaussian on Farber

Templates for Grid Engine queue submission scripts are available for batch Gaussian jobs in /opt/shared/templates/gridengine/gaussian. Copy and edit the template based on your job by following the usage described in g09.qs.

It is a good idea to periodically check in /opt/shared/templates/gridengine/gaussian on a specific cluster for changes in existing templates, or the addition of new templates, designed to provide the best performance for a particular version of Gaussian on that cluster.

Batch job using Job Class

Starting in Univa Grid Engine 8.2 on Farber, a job class is available that simplifies the submission of Gaussian jobs.

A "job class" is a template created by the system administrator that defines implicit options that will be applied to a qsub job submission. For Gaussian jobs the "gaussian" job class can be used. There are several variants of the job class:

Job Class Properties
gaussian 10 cores (half node)
gaussian.single 1 core
gaussian.small 2 cores
gaussian.large 20 cores (full node)

Given a Gaussian input file, H2O.com,

H2O.com
#  M06   opt

water optimization

0 1
O
H  1  r1
H  1  r1  2  a1

r1=0.9
a1=120.0

the user need not write a job script but can issue the following command:

  qsub -jc gaussian.single -N water -- H2O.com

A job will be submitted that when executed uses the default version of Gaussian (e.g. g09d01) on a single processor with the H2O.com input file. To use a full node for the job, only the job class needs to be modified:

  qsub -jc gaussian.large -N water -- H2O.com H2O-20C.log
