Cluster Login Access to ARC Armis2 and Lighthouse Clusters (HPC)

Environment

Advanced Research Computing (ARC) high-performance computing clusters with elevated restrictions for access:

Issue

A cluster login for the Armis2 or Lighthouse high-performance computing clusters cannot be created without having present access to, at minimum, one computing account.

Computing account access can only be granted by a computing account resource owner.

  • A cluster login must be created in order to access ARC clusters and specific computing resources. What is a cluster login? 

Resolution

Armis2 and Lighthouse cluster login access will only be authorized by following these steps in this order:

  1. An ARC project owner or a designated ARC administrator authorizes you to use a computing (Slurm) account on the Armis2 or Lighthouse cluster that they own or manage.
  2. The ARC project owner or project administrator uses the Resource Management Portal (RMP) to give you access to that computing account.
  3. After Armis2 or Lighthouse computing account access is granted then a cluster login request for the cluster that the account is on can be sent to ARC.

Cluster login access requests cannot be processed for Armis2 or Lighthouse without access to a computing account . 

  • If access to a Armis2 or Lighthouse computing account is gained following a previous cluster login access request that is now closed, then a new Cluster Login Request form must be sent.

Cluster login request forms are exclusively for cluster login requests, and cannot be used to request services, request service access, or grant access to any ARC services or project resources.

If you need to access specific ARC resources such as a computing (Slurm) account for a project or class, or a storage volume:

  • Contact the owner of that resource, or an ARC project administrator that has been designated by the owner, and ask them to grant you access.
  • Project owners and their designated administrators can manage resource access directly in the ARC project portal.

Additional Information

ARC resource access

If access is needed to a specific Advanced Research Computing service resource, such as an ARC project's computing (Slurm) account, a class computing (Slurm) account, or a storage volume:

  • Contact the owner of that resource, or an ARC project administrator that has been designated by the owner, and ask them to grant you access.
  • Project owners and their designated administrators can manage resource access directly in the ARC project portal (RMP).

All access to ARC resources is restricted. Only the project owner (most often the individual faculty member or researcher who originally requested the service from ARC, and therefore "owns" that resource) or any ARC project administrators that the project owner may have designated, is authorized to grant access to an ARC service resource. They can do this directly with the Resource Management Portal (RMP)

Partnership Programs that give access to Advanced Research Computing (ARC) Services

There are many university programs available to eligible university members that will cover costs of ARC service resources.

  • These requests must come from the ARC project owner or one of their specifically designated administrators, and be made directly to ARC.
