Description

Performance analysis is essential in the process of understanding application behavior, identify critical performance issues as well as adapting applications to new architectures and increasingly scaling HPC systems. However, in many cases expert knowledge and experience is required to identify the most productive direction of code refactoring. As a result, many codes used and developed by domain experts fall short in using the hardware efficiently, need much more compute time than needed, waste energy, require oversized and expensive hardware, or just miss research potential as their codes can only handle smaller or less complex problems. The EU H2020 Center of Excellence (CoE) for Performance Optimization and Productivity (POP) provides performance optimization and productivity services for academic and industrial codes. The services reach from a primary audit giving an overview of the behavior, performance and scalability of the application; to a detailed analysis with specific code optimization recommendations; up to a proof-of-concept implementation of the recommended optimizations. The talk will introduce the POP center of excellence and the provided services, give insight into the day-to-day work of identifying the main issues and areas for potential improvement, and discuss examples of successful analyses and code optimizations.
Michael Wagner received the M.Ed. degree in mathematics and computer science and the Ph.D. degree in computer science from the Technische Universität Dresden, Dresden, Germany, in 2008 and 2015, respectively. He was a research scientist in performance analysis at the Center for Information Services and HPC (ZIH), Dresden, Germany and is currently a HPC application analyst at the Barcelona Supercomputing Center (BSC), Barcelona, Spain. His research interests are in high performance computing with emphasis on performance analysis.
