Cluster Login for Access to ARC Clusters (HPC)

Environment

Advanced Research Computing (ARC) high-performance computing clusters.

Issue

A cluster login must be created in order to access ARC clusters and specific computing resources. 

• Elevated restrictions are in place for login access to ARC Armis2 and Lighthouse clusters

Resolution

To request a cluster login:

1. Complete the Cluster Login Request form.
2. Wait for the form to be reviewed and processed by an ARC team member.

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). 

Create or modify an ARC resource

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

For any questions, support, or assistance with ARC services, please refer to ARC support documentation or reach out to ARC directly.

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.
