Visualization: Cerberus

cerberus.nic.uoregon.edu

Cerberus is one of two publicly reachable login nodes.

Cerberus is the gateway to the "upstairs" mini-cluster, consisting of 16 NUC mini-workstations and 16 Tegra (ARM-64 + CUDA) nodes, and the upstairs provider of large-volume storage (/home/users and /packages) for Cerberus, Chymera, nuc/jetson cluster, xavier, od1k and ryzen.

Cerberus is in the process of being decommissioned. It is replaced by Sphinx.

OACISS-wide node monitor (Ganglia)

Cerberus runs a Ganglia cluster monitor, accessible from UOnet only (128.223/16) at [[1]].

The ganglia monitor provides continuous real-time updates on the state of all OACISS computing resources.

NUC/Jetson Cluster Manager

Cerberus is the head node for the NUC+Jetson (+Xavier?) mini-cluster.
