Annotation Performance Modeling, Benchmarking and Simulation of High Performance Computer Systems (PMBS16) held as part of ACM IEEE Supercomputing 2016 (SC16), Salt Lake City, UT, USA 7th International Workshop in The PMBS16 workshop is concerned with the comparison of high performance computer systems through performance modeling, benchmarking or through the use of tools such as simulators We are particularly interested in research which reports the ability to measure and make tradeoffs in software hardware co design to improve sustained application performance We are also keen to capture the assessment of future systems, for example through work that ensures continued application scalability through peta and exa scale systems The aim of this workshop is to bring together researchers, from industry and academia, concerned with the qualitative and quantitative evaluation and modeling of high performance computing systems Authors are invited to submit novel research in all areas of pe.
