Shared Scalable Compute Cluster for Research (Hyak)
NextGen Hyak is coming soon!
The next generation of the UW-IT Hyak supercomputer is on its way.
What about Classic Hyak?
You can continue to use Classic Hyak until its end-of-life, scheduled for 7/1/2020. However, please be aware that you cannot purchase new Classic Hyak nodes nor can Classic Hyak be modified or receive additions.
How do Classic Hyak and NextGen Hyak compare?
Classic: 11,000 cores or 250 TF (current performance)
NextGen: ≈9,000 cores or ≈300 TF (initial config); ≈40,000 cores or ≈1 PF (peak performance

What is Hyak?
Hyak is part of an integrated, scalable, scientific supercomputing infrastructure operated by UW-IT. It includes the lolo Archive and Collaboration File Systems, and a high-performance research network. The network supports fast data transfers among these systems, and between them and the campus and the Internet, as illustrated in the following diagram.
Hyak is made up of two clusters to allow non-disruptive technology refresh. Each Hyak cluster shares:
- A common job scheduler
- High-performance scratch storage
- Login/data-mover nodes with high speed external network links
Participating academic units (see Additional Information) invest in a common high-performance infrastructure, while individual users fund the purchase of compute nodes and supplemental storage configured according to their specific requirements. The system design guarantees users immediate access to their own nodes as well as allowing users fair access to idle CPUs throughout the cluster.
Hyak is an excellent option for research groups requiring a fast, convenient, flexible, and cost effective alternative to operating their own scalable, high-performance computing resource.
Customers may purchase between one and more than 100 compute nodes. Supplemental scratch storage is available in 1 TB increments that are billed monthly.
Customers may install and use nearly any software they like - including commercial and scientific applications - provided they are supported by the Hyak operating environment. See the Hyak User Documentation for more information.
Customers may configure one or more of their nodes for per-core, rather than per-node, scheduling. Typically this configuration is used by groups who intend to use some of their Hyak capacity for interactive, rather than batch-mode, operations. Nodes configured in this fashion support a number of separate sessions equal to the number of CPU cores. For example, a 16-core node would support 16 separate interactive sessions.
Customers may assign one or more users as group admins with the authority to add and remove user access to the system, and modify job priorities.
UW faculty, staff, researchers, academic units; and UW affiliates associated with a sponsored academic unit are eligible to purchase nodes. Students at the Seattle campus are able to access Hyak computing nodes at no cost through membership in the High Performance Computing Club (HPCC).
Evaluation accounts are available upon request.
How to Order
Email email@example.com and include the service name "Hyak" in the subject line.
Hyak is designed to be available 24x7x365 with minimal unscheduled downtime. Portions of Hyak are offline for up to eight hours monthly for scheduled maintenance. The scheduled maintenance windows are as follows:
- Between 9:00 a.m. and 5:00 p.m. on the second Tuesday of every month.
- Every third month (January, April, July, October) the maintenance window will last from Tuesday 9:00 a.m. until 9:00 a.m. the following morning.
Typically, new equipment is deployed within six weeks of the purchase order clearing UW Purchasing.
When you purchase a Hyak node, the price quoted below is the price you pay for the service, as described previously in the Service Description section. You are not charged for indirect costs, overhead, or sales tax. Compute nodes are operated for four years. Prices are updated approximately quarterly. you may purchase supplemental storage at a monthly rate of #10.00 per TB. Storage prices are subject to revision annually.
Sample prices for computer notes, including all supporting infrastructure, are show in the following table.

Service Level Description
Hyak support responds to problem reports in one to four hours. The response can be escalated if there is a critical problem. Our goal is always to minimize user downtime by responding as quickly as possible.
Hyak User Documentation provides detail instruction on how to interact with the system.
Hyak infrastructure and operations are funded by various Sponsors, each of which is entitled to a portion of the system's overall capacity. All customers deploying equipment in Hyak must receive the approval of their sponsor, typically their Dean's office. UW-IT can manage the approval process. Academic units currently sponsoring Hyak are:
- The College of Arts and Sciences
- The College of Engineering
- The College of the Environment
- The iSchool
- The School of Medicine, Baker Lab
- The School of Medicine, department of biochemistry
- UW Bothell STEM program
Other academic units interested in sponsoring Hyak capacity must be approved by the Hyak Governance Board and are limited by available data center capacity.
Hyak is a word in Chinook Jargon, meaning "fast." Chinook Jargon is the trade language of the Pacific Northwest, incorporating terms from Chinook and Chehalis and other local languages, as well as French and English. We've chosen words from Chinook Jargon for the names of systems in the UW research cyber infrastructure to emphasize their role in supporting the broad range of UW research users and our ties to our place between the mountains and Salish Sea.
