See more remote resources for connecting from home.

  • Connect to university research resources: A U-M Virtual Private Network (VPN) is required to access all ITS Advanced Research Computing (ARC) services including Great Lakes HPC Cluster, Armis2 HPC Cluster, Lighthouse HPC Cluster, Cavium/ThunderX Cluster, ConFlux, and Secure Enclave Services (SES). Be aware that performance may be slower due to the different internet capacity of home networks.
    Alternatively, use secure shell (SSH) to and then SSH again to appropriate ARC resources. Follow the command line documentation for the specific ARC resource. To use, you must have AFS storage.
  • Access research data storage: Contact ARC at [email protected] to arrange alternative access to your data if you cannot access data stored on Turbo Research Storage, Locker Large-File Storage, or Data Den Research Archive.
  • Data transfer: For reliable file transfers with or without VPN, use Globus File Transfer to access your research data. Globus is supported on the Great Lakes HPC Cluster, Lighthouse HPC Cluster, ConFlux, and the Cavium/ThunderX Cluster. For other systems continue to use scp/sftp or other supported transfer. Contact [email protected] for help.
  • Michigan Medicine VPN: Most ARC services are accessible from the Michigan Medicine VPN. Secure Enclave Services (SES) and CIFS exports on Turbo or Locker storage services are known exceptions.
    If you are using the Michigan Medicine VPN and you cannot access ARC resources, try disconnecting from the Michigan Medicine VPN, and then connecting to the U-M VPN. If that does not work or you have questions, contact ARC at [email protected].
  • Great Lakes On-Campus Queue: Log in to the on-campus login node to access the software provided there. The usual access off-campus restrictions will be temporarily lifted to match the regular, Great Lakes HPC Cluster queues.
