Decide Which Cluster to Use

See the Research Computing Systems overview page to decide which cluster is best suited for your work.


Get An Account for Your Chosen Cluster

Although you can visit each cluster's page for specific information on accessing a cluster, below we provide a general overview across the clusters, in addition to specific guidelines on accessing the larger clusters.

For Small Systems (Nobel, Adroit): Self-Register

Two small clusters are available on request to all Princeton faculty, students and staff:

  • Adroit is used for small production runs, training and classes
  • Nobel is used mainly for classes

To request an account, first make sure your NetID is enabled for Unix.

For Nobel, no further action is needed. All Princeton faculty, students, and staff have automatic access.

For Adroit, fill out the online registration form (Adroit registration). You will be notified once your account is approved.


For Large Clusters (Della, Stellar, Tiger, Traverse): Submit a Proposal, Contribute, or Sponsor

Access to the large clusters is granted on the basis of brief faculty-sponsored proposals (see "Proposal Guidelines" below). Access is also granted to members of research groups where the faculty member has contributed to the purchase of a cluster.

Contributions and priorities

There are no fees to use the systems; however, faculty can contribute to the purchase of our systems.  By contributing to a system, a faculty member guarantees that averaged over some time period (two weeks or 30 days depending on the system) members of that group will be able to utilize the proportion of the system corresponding to the contribution.  Unused system capacity is available to all other researchers on the system.

If you are interested in contributing to the purchase of a new cluster or an expansion of an existing  system, please contact

Sponsor a user

A faculty contributor or a faculty member with an approved project can sponsor additional users by sending a request to Any non-Princeton user must be sponsored by a Princeton faculty or staff member for a Research Computer User (RCU) account.


Proposal Guidelines

Proposals for the large  cluster systems should be submitted as PDF or MS Word documents not to exceed 3 pages. The proposal, which can be submitted through an online form, should include:

  • Which system or systems you need to use (e.g., Della)
  • A list of researchers who will need accounts
  • The faculty member(s) who is sponsoring the project
  • The scientific background for your project including scientific merit of the proposed work
  • The programming approach for your project:
    • Programming language(s)
    • Parallelization mechanism (e.g., MPI or OpenMP)
    • Required libraries
  • The resource requirements for your project:
    • Number of concurrent CPU-cores
    • GPUs
    • Total CPU time
    • RAM per task
    • Total disk space
  • A few references or citations



There is no charge for storage. The large HPC clusters provide a variety of filesystems for storage. Nobel uses the OIT home filesystem. Adroit has its own filesystem.
