New Users

Access to RCS resources requires that you be a member of a project established by a UA principal investigator. Tenured or tenure track faculty, research faculty and emeritus faculty are normally allowed to serve as a principal investigator. Other university employees, including staff, research associates or post-doctoral fellows, may not serve as principal investigators unless granted an exception by their institute director or academic dean with the approval of the UAF Office of Sponsored Programs.


UA Principal Investigator

To establish a new project please fill out the project account application form.

Principal investigators are responsible for the members, storage and other resource use of a project, and if additional resources are needed that are not covered by RCS subsidized services, procurement will be routed through the PI.

Prior to establishing a project the principal investigator should note any special data management needs such as any obligations on data security, how long data must be retained, and/or ITAR compliance, and notify RCS during the project creation process.


UA Collaborator

If you are a UA principal investigator wanting to collaborate with non-UA colleagues on RCS or UA systems, please email with the subject: "Guest Account Application." Please include your project name and the collaborator's first name, last name and email address. Sponsored user accounts expire annually on June 30.

UA Classes and Course Instructors

Instructors may request a project for their classes. Please complete a project account application form and user account application form, and provide a list of students and their UA usernames to be added to the class project. One TB of long-term, offline tape storage ($ARCHIVE) is provided for class projects. Student data stored in the high performant online spinning disk ($CENTER1) will be deleted annually at the end of the spring semester. Class accounts must be renewed annually.

UA Staff or Student

You will need to fill out a user account application form and the project PI must email RCS to request to add you as a member of their project. 

High Performance Computing

Are you interested in using the Chinook HPC cluster in your computational work? Please read our directions on how to obtain RCS project and user accounts.

In 2016, the Geophysical Institute launched Chinook as an energy efficient Linux cluster purchased from Penguin Computing, Inc. Chinook is a condo-style HPC cluster for UA researchers. As of April 2024, the computing environment includes:

  • 81x Relion 1900 Compute Nodes each with dual Intel Xeon 12- or 14-core processors (24 or 28 cores per node) and 128 GB memory
  • 38x Relion XE1112 Compute Nodes each with dual Intel Xeon Scalable 20-core processors (40 cores per node) and 192 GBs memory

High-Performance Computing Storage

High-Performance Computing storage ($CENTER1) is high throughput, scratch storage available to Chinook users. $CENTER1 is a Lustre filesystem best used for large files. Reading or writing many small files may result in a noticeable performance reduction.

As a scratch workspace, data in $CENTER1 is not backed up. Files requiring long-term storage should be copied to a different system or filesystem such as $ARCHIVE. Data in $CENTER1 is not purged, but if files are deleted or overwritten or the filesystem crashes or is corrupted, there is no restoring the data if there isn't a copy elsewhere except to regenerate it.

Projects are subject to a quota in $CENTER1. Quotas and utilization may be checked using the “show_storage” command. Always check to see if there is storage available for your date to be written as files that go over the quota may be truncated, unwritten, or block other write access to the filesystem. If you need to temporarily use more than your project's quota of scratch space, contact to request a temporary increase for up to 30 days. Include how much additional space is needed and a paragraph justifying the need for additional space.

Subsidized quota: 1 TB per project

Online Spinning Disk

Online spinning disk is used to share data and VM storage. Data may be backed up automatically to $ARCHIVE for an additional service fee or principal investigators may back up online spinning disk data manually to their $ARCHIVE account using their subsidized 10 TB or any additional purchased $ARCHIVE storage. Online spinning disk storage will generally perform more slowly when used with high-performance computing.

Offline Tape Archive

The offline tape archive ($ARCHIVE) is a long-term storage solution for infrequently accessed data, such as retention of completed work or an archive of data. Data stored in $ARCHIVE is written out to magnetic tape and must be retrieved when copied to another filesystem, resulting in very slow access times. Files in $ARCHIVE should be copied or moved to another filesystem before modifying or using the files.

Principal investigators in $ARCHIVE are subject to quota. When quota is reached files may no longer be written, and a file that is currently being written to the filesystem may be truncated or deleted, and access to writing and moving files may be lost. It is always recommended to check that there is enough space to write your file. Quotas and current usage can be viewed with the “show_storage” command.

Subsidized quota: 10 TB per Project Investigator

Web Services

Content Management Systems


Drupal is a popular open source content management system (CMS). The Drupal community provides thousands of themes and plugins to customize the appearance and functionality of websites. Its modular architecture makes Drupal an ideal choice for rapid development of virtually any type of website.

Examples of the many things that can be built with Drupal include:

  • Websites with complex access roles and editing privileges.
  • Conference websites with attendee abstract submission and review systems.
  • Audio/video content catalogs that are simultaneously served out as podcasts.
  • User-friendly databases with intricate tagging and searching systems to aid discovery.
  • API endpoints that integrate with other web applications or mobile apps.

For more information, see RCS provides full support for Drupal hosting, including consultation and development services.


WordPress is another popular CMS that is geared towards blogging. Like Drupal, the WordPress community provides thousands of themes and plugins to customize the appearance and functionality of your website. WordPress is best suited for:

  • Small-to-medium sized websites.
  • Websites with frequent blog entries and simple, static web pages.
  • Ease of use at the expense of flexibility.

For more information, see RCS provides limited support for WordPress hosting.
