We present a monitoring and analysis tool prototype for system wide monitoring of High Performance Computers. The tool uses formal specification of properties which are based on hardware counters. These evaluate the performance at different granularities, namely at core, application and partition graininess. The information obtained is aimed at detecting single node performance as well as parallel execution performance. The goal is to identify performance bottlenecks in running applications as well as the general system behaviour. The scalability in our prototype for highly parallel machines is achieved through a distributed software architecture. We use an analysis agent at each partition. These agents communicate to a high level agent using a communication protocol based on TCP/IP. The high level agent has as a main task the synchronisation of the rest of the agents. Moreover, the analysis agents have the capability to use OpenMP within each partition to parallelise their monitoring tasks. Our approach used to tackle the storing of large amounts of information is achieved by data reduction. Only the properties that detect a bottleneck are stored, thus we don’t compromise the quality of the needed monitoring information.
