Years ago, it was common to write a for-loop and call it benchmark. Nowadays, benchmarks are complex pieces of software and specifications. In this talk, the idea of benchmark engineering, trends in the area of benchmarking research and current efforts of the SPEC Research Group and the WBDB community focusing on Big Data will be discussed. The way in which benchmarks are used has changed. Traditionally, they were mostly used for generating throughput numbers. Today, benchmarks are, e.g., used as test frameworks to evaluate different aspects of systems such as scalability or performance. Since benchmarks provide standardized workloads and meaningful metrics, they are increasingly important for research.
The benchmark community is currently focusing on new trends such as cloud computing, big data, power-consumption and large scale, highly distributed systems. For several of these trends traditional benchmarking approaches fail: how can we benchmark a highly distributed system with thousands of nodes and data sources? What does a typical Big Data workload look like and how does it scale? How can we benchmark a real world setup in a realistic way on limited resources? What does performance mean in the context of Big Data? What is the right metric?
Speaker: Kai Sachs is a member of the Lifecycle & Cloud Management group at SAP AG. He received a joint Diploma degree in business administration and computer science as well as a PhD degree from Technische Universität Darmstadt. His PhD thesis was awarded with the SPEC Distinguished Dissertation Award 2011 for outstanding contributions in the area of performance evaluation and benchmarking. His research interests include software performance engineering, capacity planning, cloud computing and benchmarking. He is co-founder of ACM/SPEC International Conference on Performance Engineering (ICPE). He has served as member of several program and organization committees and as reviewer for many conferences and journals. Among others he was the PC Chair of the SPEC Benchmark Workshop 2010, Program Chair of the Workshop on Hot Topics on Cloud Services 2013 and the Industrial PC Chair of the ICPE 2011. Kai Sachs is currently serving on the editorial board of the CSI Transactions on ICT, as vice-chair of the SPEC Research Group, as PC Co-Chair of the ACM/SPEC ICPE 2015 and as Co-Chair of the Workshop on Big Data Benchmarking 2014.
