The General Atomic and Molecular Electronic Structure System (GAMESS)[1] is a general ab initio quantum chemistry package.


Running GAMESS

Our Clusters are using the Slurm scheduler; for details about submitting jobs, see Running jobs.

First step is to prepare a GAMESS input file containing the molecular geometry and run parameters. Please refer to the GAMESS Documentation[2] and particularly Chapter 2 "Input Description"[3] for a description the file format and all available keywords.

Besides your input file (in our example name.inp), you have to prepare a job script to define the compute resources for the job; both input file and job script must be in the same directory.
