HYAK is part of the University of Washington's cyberinfrastructure plan to support world-class research in every department. HYAK is an ecosystem of high-performance compute (HPC) clusters and supporting infrastructure (e.g., data management, computational training, scientific consulting). Acknowleding our Pacific Northwest heritage, HYAK means "fast" in Chinook jargon. Counting 1, 2, and 3 translates to "ikt", "mox", and "klone" in this local trading language. The numbers are cluster names corresponding to the generation of HYAK cluster deployed. We are currently on the 3rd generation cluster for HYAK.

1. ikt
2. mox
3. klone


Cluster	`ikt`
Service	October 2010 — June 2020
Operating System	CentOS 6
Compute	8,008 CPU cores [Broadwell]
Accelerators	47 GPU cards [Tesla M2075]
Interconnect	10 Gbps [Myri-10G Myrinet]
Topology	Non-blocking 1-layer fat tree
Storage	1.0 PB GPFS
Notes	Ikt translates to 1 in Chinook trading jargon and was the name of the 1st HYAK cluster. `ikt` is no longer in service. Reported figures represent best records.


Cluster	`mox`
Service	June 2018 — June 2024 (Estimated)
Operating System	CentOS 7
Compute	18,376 CPU cores [Cascade Lake]
Accelerators	112 GPU cards [Turing] 20 Xeon PHI
Interconnect	100 Gbps [OPA100 Omnipath]
Topology	Non-blocking 1-layer fat tree
Storage	1.0 PB GPFS
Notes	Mox translates to 2 in Chinook trading jargon and is the name of the 2nd HYAK cluster. `mox` is active but no longer accepting node additions and not growing. Reported figures represent peak capacity during its service.


Cluster	`klone`
Service	January 2021 — Present
Operating System	Rocky 8
Compute	21,028 CPU cores [Cascade Lake, Ice Lake]
Accelerators	576 GPU cards [Turing, Ampere]
Interconnect	100 Gbps [HDR100 Infiniband]
Topology	3:1 blocking 2-layer fat tree
Storage	2.7 PB GPFS 500 TB NVMe Flash
Notes	Klone translates to 3 in Chinook trading jargon and is the name of the 3rd HYAK cluster. `klone` is active and scheduled for a soft launch in Q1 2021 and a full launch by Q2 2021. Reported figures are updated as the cluster continues to grow.
