On September 22nd, OSC switched to Slurm for job scheduling and resource management on the Pitzer Cluster, along with the deployment of the new Pitzer hardware. We are in the process of updating the example job scripts for each software. If a Slurm example is not yet available, please consult our general Slurm information page or contact OSC help.

GAMESS

The General Atomic and Molecular Electronic Structure System (GAMESS) is a flexible ab initio electronic structure program. Its latest version can perform general valence bond, multiconfiguration self-consistent field, Möller-Plesset, coupled-cluster, and configuration interaction calculations. Geometry optimizations, vibrational frequencies, thermodynamic properties, and solution modeling are available. It performs well on open shell and excited state systems and can model relativistic effects. The GAMESS Home Page has additional information.
