Abstract

We have developed a Quantum Chemistry Grid (QC Grid) for simple and effective use of computer resources for ab initio molecular orbital calculations. Ab initio is a powerful methodology in computational chemistry. Gaussian is one of the codes widely used in quantum chemistry research, and it is used not only by quantum chemistry experts, but also by non-experts. Since the CPU cycles of Gaussian jobs vary significantly with the input parameters, it is difficult for users to choose the most adequate computational resources in a local computing environment. By using grid technology on top of a high-speed network environment, QC Grid enables users to easily share the knowledge of experts and efficiently utilize costly computational resources without having to know the specific system environment. Gaussian Portal is the first implementation of the QC Grid concept. It consists of a Web interface, a meta-scheduler, computing resources, and archival resources on Grid infra-wares.
