Pleiadi@IRA Cluster Technical Improvements Report

Key Points

The report aims to document infrastructure improvements for enhancing energy efficiency and resource management in the Pleiadi@IRA HPC cluster.
Implemented an automatic power management system for dynamic control of compute node power states.
Utilized Slurm accounting data for comprehensive monitoring.
Employed Prometheus for data acquisition and Grafana for visualization of monitoring data.
Achieved a 61% reduction in idle power consumption.
Improved overall energy usage efficiency of the HPC cluster.

Abstract

This technical report documents the implementation of key infrastructure improvements to the Pleiadi@IRA HPC cluster, focusing on energy efficiency and resource monitoring. The primary improvements include: (1) an automatic power management system that dynamically controls compute node power states based on workload demand, achieving a 61% reduction in idle power consumption; and (2) a comprehensive monitoring infrastructure using Slurm accounting data exported to Prometheus and visualized through Grafana dashboards.
