Our April maintenance is complete, and Klone and Tillicum are back in operation. The next maintenance is scheduled for Tuesday, May 12, 2026. During this month’s scheduled maintenance window, we completed several system upgrades and routine updates across Klone and Tillicum to improve stability, performance, and security.

Notable Updates​

In addition to routine package and security updates, we completed the following user-relevant changes:

  • Open OnDemand ADA Update - This update includes improvements for digital accessibility.
  • Upgrade of Globus on Klone and Tillicum - This update fixes the access/permission issues.

New: Tillicum GPU Credits for Students​

UW students can now apply for $250 in Tillicum GPU computing credits to support research projects, class work, and technical exploration that benefit from high-performance GPUs. Tillicum features NVIDIA H200 GPUs and is designed for workloads that can take advantage of large GPU memory or multi-GPU scaling.

These credits are provided by the Research Computing Club, with funding from Student Technology Fees, to help expand student access to advanced research computing resources.

Important Storage Reminder for Hyak Klone​

Hyak Klone does not provide backup, persistent storage, or archival storage. All data on Klone exists as a single copy and is therefore vulnerable to loss due to hardware failure, filesystem issues, facility damage, or natural disasters. Users are solely responsible for transferring important results to external systems (for example, Kopah S3 or Lolo Archive) during the course of their project if persistent or long-term storage is required. Retaining long-term or archival data on Klone is against administrative guidance.

Upcoming Events & Workshops​

  • Multi-GPU PyTorch Workshop – Join us on Tuesday, April 21, 2026, from 10 AM–12 PM in Room 371 CSE2/Gates Hall or online via Zoom. This NVIDIA-led, hybrid training will guide practitioners with existing PyTorch scripts in scaling workloads using Distributed Data Parallel (DDP) and NVIDIA Nsight tools. Participants will learn recommended DDP patterns, avoid common throughput pitfalls, profile and diagnose performance bottlenecks, and practice hands-on exercises to analyze GPU utilization, CPU/GPU interactions, and other performance signals.
  • Quantum Hackathon with IBM Quantum – Join us on Thursday, May 14, from 10:00 AM–5 PM in the UW Tower South Cafeteria for a quantum computing hackathon on Quantum Machine Learning co-organized with IBM Quantum. This hands-on coding event will explore quantum computing through guided challenges and collaborative problem-solving. Participants will work with IBM Quantum tools to experiment with quantum algorithms on real hardware and simulators. This event is open to anyone interested in learning by doing—no previous quantum experience required. Lunch will be provided for participants.
  • AWS Kiro - Getting Started from Build to Operate – Join us on Tuesday, May 19, from 10:00 AM–4 PM in CSE2/Gates Hall Room 371 for a hands-on session where you'll explore the capabilities of Kiro, an AI-powered assistant designed to accelerate software development and cloud operations. Lunch will be provided for participants.
  • 2026 VISIONS cruise is taking undergraduate applications – no experience needed, just enthusiasm to learn about oceanography while going to the sea for 12 days this August on a 270-foot research vessel. The application deadline is April 15, with possible extensions.
