Description
The Pleiadi@IRA cluster is a High-Performance Computing facility operated by INAF - Istituto di Radioastronomia in Bologna, Italy. As HPC facilities face increasing pressure to reduce energy consumption while maintaining service availability, we implemented two complementary systems: 1. Automatic Power Management: Dynamic power control of compute nodes based on Slurm scheduler demand 2. Resource Monitoring: Real-time tracking of cluster utilization through Prometheus/Grafana integration
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.
