In an E-HPC cluster, a user is an identity that submits jobs and accesses cluster resources. Cluster administrators create users with different permission levels to separate administrative control from day-to-day job submission.
Why create cluster users
Cluster users serve three purposes:
Access control: Assign different permissions to different users on resources and data. This separates cluster management from job submission and keeps data secure.
Identity authentication: Each user has a verified identity. Only users with valid credentials and the right permissions can perform specific operations.
User management: Register new users, manage passwords, and organize users into user groups to ensure information and permission validity and security.
User types
E-HPC clusters have two user types:
| User type | Capabilities |
|---|---|
| Sudo permissions users | Run system services and perform management operations. |
| Ordinary permissions users | Submit jobs and use cluster resources. Each ordinary permissions user has their own username and password. Cluster administrators create and assign these users. |
