Cayuga is a private cluster with restricted access. Access to the Cayuga cluster is restricted to connections from the Cornell Ithaca or Weill VPNs.

Athena

  • Parallel File System (3.8P)

  • Each of the cayuga projects will have a setup: /athena/cayuga_####/scratch/[cwid]

  • There is also a symlink from the labname per cayuga project: /athena/[labname] --> /athena/cayuga_####

Accessing the cayuga cluster

  • Once you have completed the form sent for gaining access via ssh to your account on the cayuga cluster, you will receive a welcome email guiding you through: CAC TechDocs

  • Access via ssh using public/privates keys – Instructions will be provided when accounts are created.

  • You will have access to all 3 of the login nodes in order to: submit jobs to the scheduler, gain access to your project data files on the /athena storage and your home directories.

  • Login nodes:

    • cayuga-login1.cac.cornell.edu

    • cayuga-login2.cac.cornell.edu

    • cayuga-vis1.cac.cornell.edu
