Topology Aware Performance Monitoring

A tool has been developed to abstract performance metrics and map them onto the hwloc (see Section 6.6) topology model of the system. During the year 2016, the tool has been entirely rewritten to release a more meaningful and stable programming abstraction, with off the shelf performance abstraction plugins and raw performance acquisition plugin [16]. A special effort has been carried out on output presentation by extending lstopo tool from hwloc into a library embedded in the monitoring tool to display performance metrics on the system topology. Another backend using R has also been developed for the purpose of post-mortem analysis and model extraction from abstract metrics of the topology.
