Collating time-series resource data for system-wide job profiling

Through the collection and association of discrete time-series resource metrics and workloads, we can both provide benchmark and intra-job resource collations, along with system-wide job profiling. Traditional RDBMSes are not designed to store and process long-term discrete time-series metrics and the commonly used resolution-reducing round robin databases (RRDB), make poor long-term sources of data for workload analytics. We implemented a system that employs “Big-data” (Hadoop/HBase) and other analytics (R) techniques and tools to store, process, and characterize HPC workloads. Using this system we have collected and processed over a 30 billion time-series metrics from existing short-term high-resolution (15-sec RRDB) sources, profiling over 200 thousand jobs across a wide spectrum of workloads. The system is currently in use at the University of Kentucky for better understanding of individual jobs and system-wide profiling as well as a strategic source of data for resource allocation and future acquisitions.
