Collecting sensor data in a high-performance computing environment: a case-study
Many research questions remain open with regard to improving reliability in exascale systems. Among others, statistics-based analysis has been used to find anomalies, to isolate root causes, and attempt to predict failures. But well-understood methods and best practices for collecting reliability data in a uniform way are still lacking, which impedes analysis. We report our experience with collecting these data from heterogeneous sources on a testbed cluster and present our data collection tool. This case illustrates the fact that reported metrics largely depend upon individual system configuration. We then investigate standards and specifications in manufacturing and desktop computing to identify concepts that may be useful for representing High Performance Computing (HPC) data and present a taxonomy that utilizes these concepts.
