Abstract
We describe the use of the Jetstream research-cloud, a purpose-built system with the goal of supporting long-tail research by providing a flexible, on-demand research infrastructure, to provide scalable back-end resources for science gateways. In addition to providing cloud-like resources for on-demand science, Jetstream offers the capability to instantiate long-running clusters which support science gateways. Science gateways are web-based systems built on computational infrastructure which provide commonly-used tools to a community of users. We created a persistent cluster on the Jetstream system which is connected to the SEAGrid science gateway and provides additional compute resources for a variety of quantum chemistry calculations. We discuss the further application of toolkits provided by the Extreme Science and Engineering Discovery Environment (XSEDE) to build general-purpose clusters on the research cloud.
