Running jobs on Cheyenne, Yellowstone, Geyser and Caldera

Where and how to start jobs on the Cheyenne and Yellowstone HPC systems and the Geyser and Caldera clusters have been common questions as more and more users begin working on Cheyenne.

The short answer is to log in to Cheyenne to run jobs on Cheyenne, and log in to Yellowstone to submit jobs to run on Yellowstone, Geyser, or Caldera.  The separate logins are necessary because the systems have different job schedulers and operating systems.

We are working to provide a more streamlined solution for Cheyenne users to run data analysis tasks on Geyser and Caldera. Users who need to transfer existing, automated workflows to Cheyenne should contact cislhelp@ucar.edu to discuss options.
