System Monitoring Meets Application Performance Analysis - The HOPSA EU-Russia Project

SESSION: System Monitoring Meets Application Performance Analysis - The HOPSA EU-Russia Project

EVENT TYPE: Birds of a Feather

TIME: 5:30PM - 7:00PM

SESSION LEADER(S):Bernd Mohr, Vladimir Voevodin, Erik Hagersten

ROOM:TCC LL1

ABSTRACT:
To maximize the scientific output of a high-performance computing system, different stakeholders pursue different strategies. While application developers are trying to shorten the time to solution by optimizing their codes, system administrators are tuning the configuration of the overall system to increase its throughput. Yet, the complexity of today's machines with their strong interrelationship between application and system performance presents serious challenges to achieving these goals. This BOF session will present strategies and preliminary results addressing this challenge developed in the EU-Russia "Holistic Performance System Analysis" project (HOPSA, http://www.hopsa-project.eu). One part consists of the collection, aggregation, and management of system-wide performance metrics as part of system monitoring. The other part comprises well-known application-centric performance analysis tools covering complementary aspects. Both will be integrated in an end-to-end performance analysis work-flow which will incorporate presently separated aspects such as system hardware status, job submission, individual application processes and parallel application behavior.
