Hyak is a service of UW-IT. You can read more about it in the Service Catalog.

Most of the nodes are devoted for computing but the cluster also includes a few "login-nodes", dedicated to logins, file transfers, and similar communication tasks. There are also nodes that belong to the sponsoring institutions, and nodes for compiling and testing the programs.

Any UW student can get access to hyak by joining the HPC club: http://students.washington.edu/hpcc/getting-started-on-hyak/

Hyak consists of two independent clusters: ikt.hyak (hyak classic) and mox.hyak (hyak next-gen). All new nodes are added to mox.hyak.

ikt

...

Contains two partitions, "p1" and "p2". Both partitions contain hundreds of nodes, each comparable to a high-end server. A typical node on ikt.hyak has 16 processor cores and 128GB of memory. All the ikt.hyak nodes run CentOS 6 Linux, and they are tied together by the Moab cluster software. The user tasks are submitted through TORQUE scheduler. ikt.Hyak is made of several generations of hardware with different levels of performance, see Hyak Node Hardware for more details.

mox

...

Contains undreds of nodes, each comparable to a high-end server. A typical node on mox.hyak has 28 processor cores and 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 Slurm scheduler.  

Most of the nodes are devoted for computing but the cluster also includes a few "login-nodes", dedicated to logins, file transfers, and similar communication tasks. There are also nodes that belong to the sponsoring institutions, and nodes for compiling and testing the programs.

Purchasing Hyak Capacity

CPU and storage options are available for purchase to Hyak users associated with sponsored campus units. New nodes will be part of mox.hyak.
