epEBench: True Energy Benchmark

Current benchmark suites for evaluating energy efficiency of modern computer systems fail to replicate real-world streaming applications accurately enough because of indeterministic load pattern which depends heavily on the input data of the application. This paper presents epEBench - an opensource multi-core benchmark specifically designed for evaluating energy efficiency. The benchmark supports workload modeling and workload level manipulation to generate realistic case studies not earlier supported by benchmark tools. We show how the workload model of two real-world applications has been extracted from their real execution and how this information has been used to create workload models for epEbench. We evaluate the accuracy of the currently created workload models and demonstrate the benchmark suite.
