Hyak consists of two independent clusters: ikt.hyak (hyak classic) and 1 cluster: mox.hyak (hyak next-genthe 2nd generation hyak system).
mox.Hyak is online.*

Hyak consists of two independent clusters: ikt.hyak (hyak classic) and 1 cluster: mox.hyak (hyak next-gen). All new nodes are added to mox.hyak.
ikt.hyak has hundreds of nodes, each comparable to a high-end server. A typical node on ikt.hyak has 16 processor cores and at least 64GB of memory. All the ikt.hyak nodes run CentOS 6 Linux, and they are tied together by the Slurm cluster software. The user tasks are submitted through the Slurm scheduler. ikt.Hyak is made of several generations of hardware with different levels of performance, see Hyak Node Hardware for more detailsthe 2nd generation Hyak system).
mox.hyak contains hundreds of nodes, each comparable to a high-end server. A typical node on mox.hyak has at least 28 processor cores and at least 128GB of memory. All the mox.hyak nodes run CentOS 7 Linux, and they are tied together by the Slurm cluster software. The user tasks are submitted through the Slurm scheduler.
CPU and storage options are available for purchase to Hyak users associated with sponsored campus units. New nodes will be part of mox.hyak.Non-sponsored campus units are able to purchase dedicated compute or storage capacity with an added annual maintenance cost.
This information is provided for preliminary planing purposes only. Please use your UW e-mail to contact email@example.com for assistance in preparing actual Hyak hardware configurations.
All Hyak use is mediated by the system scheduler. This section provides details on using the scheduler to run interactive, batch, and parallel jobs. It also includes instructions for using the scheduler to monitor your jobs and the cluster status.
ikt.hyak uses the slurm scheduler. Jobs must be submitted via login nodes.
mox.hyak uses the slurm scheduler. Jobs must be submitted via the login nodes.

If you use the STF (Student Technology Fee) allocation through the Research Computing Club (RCC), please join the mailing list for the RC club RCC (https://depts.washington.edu/uwrcc/) and direct all questions there. Do not contact UW-IT for support.
The principle means of support we provide is this Wiki - a comprehensive set of documentation covering all basic Hyak functions. If you encounter problems with one of Hyak's basic functions use your UW e-mail to send an e-mail to firstname.lastname@example.org with 'hyak' as the first word in the subject and a brief description of your issue. If you do not use your UW provided e-mail account, please include your UW NetID in your e-mail. If you're reporting a problem with a job or the job scheduler, please include at least one affected jobid as well as paths to the job script and job stdout.
