Monthly User Conference Calls

Omnistat provides a set of utilities to aid cluster administrators or application developers to aggregate scale-out system metrics via low-overhead sampling across all hosts in a cluster or, alternatively on a subset of hosts associated with individual user jobs. At its core, Omnistat aggregates key telemetry from diverse subsystems, including memory/compute usage on AMD Instinct accelerators, network interface traffic, power/energy usage, and hardware performance counters. This talk will present an overview of Omnistat’s architecture, available metrics of interest, and example usage demos on ORNL's Frontier supercomputer targeting end-users with SLURM job-script examples.
