Hyak User Agreement

Hyak Use & Purchasing Agreement Policy for the College of the Environment

Purpose

The College of the Environment continues to invest in Hyak, UW’s High-Performance Computing (HPC) facility that support computational science that exceeds the resources of your personal or laboratory systems.

Rationale

High Performance Computing is essential to scientific discovery and to advancing many fields of science. It is the key to furthering the environmental sciences and many other areas that significantly impact society. The amount of data available in the environmental sciences has grown exponentially over the last decade, and the wide availability of the output from model simulations has accelerated discovery. HPC at UW (University of Washington) provides the necessary infrastructure to: (a) share expertise and experience in high performance computing and data, scientific computing, and its application across a broad range of disciplines that are critical to the State of Washington and the nation; (b) educate the next generation of leaders who will continue to address the most challenging scientific, engineering, and societal problems; and (c) enhance UW’s leadership in research and education by providing faculty, students, researchers, and staff with access to, and the capability to use, the HPC resources that they require.

Hyak provides a scale of computing that falls in between typical laboratory-scale computing and what is available at large super-computing facilities. With Hyak, UWIT (UW Information Technology) provides a central space with air conditioning, power, disaster recovery, backup, and high-speed networks for HPC infrastructure. UWIT provides operational and technical support to HYAK node owners and users. Individual large units (primarily colleges) are designated Tier Sponsors if they purchase large quantities of slots at a discounted price. The annual (yearly with a 4-year contract) non-tiered slot cost is $1,750 per slot. Tier sponsors save their node owners a minimum of $950/year or $3,800 over 4 years per slot. Tier sponsors decide how to share and use their allotted slots beyond or in accordance with HYAK polices set by the HYAK Governance Board. Individual Pis or laboratories purchase computer nodes which reside in the slots. High-performance computers are more efficient when all the nodes are in use resulting in big advantages for owners and users of HYAK computer nodes. These advantages include the use of unused nodes for computing jobs (as designated by HYAK itself) as well HYAK will continually become faster as users either update or add in new faster nodes after the 4-year node end-of-life cycle. The same computing job that was submitted 4 years ago will be much faster 4 years later as new generational nodes are brought in to HYAK.

College of the Environment Support

The College of the Environment is designated as a Tier 1 sponsor and has a 5-year commitment to purchase 100 slots at a discounted price of $800 per slot in Hyak for the period FY23 to FY28. Hyak is made up of CPU and GPU nodes with specific specifications and they must be purchased through UWIT (for reasons of hardware homogeneity). Nodes are priced to include the support for managing the nodes over their lifetime (4 years).

eSITS, the College of the Environment Shared Information Technology Services group (esits@uw.edu) is available to help users within the College with Hyak access, use, checkpoint scheduling, questions and learning how to utilize Hyak and HPC for their research needs.

The College of the Environment’s 5-year MOU/commitment breaks down to:

  • Initial $60,000 payment for Level 2 Sponsorship for initial 60 slots in FY23.
  • Annual payments of $80,000 for Level 1 sponsorship for 100 slots in FY24 – FY28.
  • Total Monetary Commitment:  $380,000
  • The College has agreed to pay $250,000 over the 5-year MOU.
  • Oceanography has agreed to pay $50,000 for 10 slots over the 5-year MOU.
  • The remainder $80,000 will be recovered from either a $400 or $200 yearly slot fee depending on when nodes were purchased. Yearly charges are effective 1/1/24 and will be prorated for FY24.

The breakdown of all 100 slots is as followed:

  • 50 Pre-2022 Node slots.
  • 40 Post 2022 Node slots.
  • 10 slots are reserved exclusively for Oceanography and are excluded from the below policies.

The College of the Environment has invested in a single compute node needed to manage all other nodes in their compute group.  Access to this single compute node and group is restricted to Post-2022 Node owners.

Use Agreement. Pre-2023 Nodes

The owners of nodes purchased before 2023 agree to the following use policy:

  • All nodes must be replaced, retired or be on an extended operation after the 4-year end-of-life cycle as outlined by UWIT’s HYAK Node Retirement Policy 2.0.
  • Node owners will be charged $400 per year for each slot they are using. Yearly charges are affective 1/1/24 and will be prorated at $200 for FY24.
  • Nodes purchased before 2023 may continue to use their own dedicated HYAK group and nodes.
  • No expansion of nodes or slots will be permitted for pre-2023 node owners.

Use Agreement.  Post-2022 Nodes

The owners of nodes purchased after 2022 agree to the following use policy:

  • All nodes must be replaced, retired, or be on an extended operation after the 4-year end-of-life cycle as outlined by UWIT’s HYAK Node Retirement Policy 2.0.
  • Node owners will be charged $200 per year for each slot they are using. Yearly charges are affective 1/1/24 and will be prorated at $100 for FY24.
  • All nodes will be purchased, maintained, and owned by eSITS. Those that wish to purchase CPU/GPU nodes may either transfer funds to the eSITS worktag or provide a worktag to eSITS at the time of purchase.
  • All nodes within the 40 slots will reside within the COENV user group.
  • Node investors will cooperatively use and share all purchased nodes in the COENV group.
  • ESITS will work with all parties to resolve disputes of computation cycles and times in the HYAK scheduler.
