September 2025 OLCF User Conference Call: Omnistat

The OLCF hosts monthly User Conference Calls. These calls are your opportunity to speak with center personnel to get the latest updates, express any concerns you may have, etc. No registration is required for this event. An email with an invite to the event will be sent to OLCF users approximately one week beforehand.

Monthly Topic:  Omnistat

Speaker: Karl Schulz (AMD), Jorda Polo (AMD), Bruno Villasenor (AMD)

Abstract:

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.
