Bridging the gap between profiling and monitoring in HPC systems with dynamically reconfigurable fine-grain data collection

Résumé

Job-aware monitoring of HPC systems is a middle ground between system monitoring and profiling as it collects performance data at the scale of a job while keeping the overhead at a reasonable amount to allow for production usage. This paper presents Colmet, a job-level monitoring system capable of collecting metrics at different sampling period at the same time. The sampling periods can be dynamically reconfigured to suit the current need of the users up to the millisecond. We these features, Colmet can be used for usual monitoring purposes and for profiling purposes. Fine grain and reconfigurable data can also be used in systems that make decisions based on performance data. Our system is at least as efficient as state-of-the-art monitoring systems as we show in the performance analysis results.
