We run the Ganglia cluster status tool on ikt.hyak. Here you can find out the details about the CPU, memory, and network usage of the nodes in your allocation. (Ganglia does not run on mox.hyak.)

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

Hyak consists of two independent clusters: ikt.hyak (hyak classic) and mox.hyak (hyak next-gen).

ikt.Hyak contains two partitions, "p1" and "p2". Both partitions contain hundreds of nodes, each comparable to a high-end PC. 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 typically submitted through TORQUE scheduler although simple programs can also be run directly. . ikt.Hyak is made of several generations of hardware with different levels of performance, see Hyak Node Hardware for more details.

mox.Hyak contains  hundreds of nodes, each comparable to a high-end PC. A typical node on ikt.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 typically 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.
