Model Runs on UW Hyak

University of Washington students and employees can request a login; this project is hosted by the Coastal group and NSF PREEVENTS project. With a Hyak login, users can interact with the job scheduler and transferdata to and from Hyak. Compute work should be done by requesting an interactive session on (or submitting batch jobs to) compute nodes.

Visit the Hyak user wiki for more details: http://wiki.hyak.uw.edu/Hyak+mox+Overview
