Several classes of applications can expose at runtime a set of software knobs (including application parameters and code transformations) to trade-off the quality of the results and the throughput. Resource management and application autotuning are key issues for enabling computing systems to adjust their behavior in the face of changing conditions, operating environments, usage contexts and resource availability while meeting energy-efficiency and Quality-of-Service requirements.
This talk will present dynamic autotuning techniques for the multi-objective optimization of applications to tune software knobs in an adaptive scenario to trade-off accuracy versus performance. Machine learning techniques are used to predict the system behavior based on a set of training data. The main challenge is to exploit design-time and run-time concepts to lead to an effective way of “self-aware” computing. The talk also presents the application of dynamic autotuning techniques to energy-efficient HPC systems.
Cristina Silvano is a Full Professor of Computer Engineering at the Politecnico di Milano, Dept. of Electronics, Information and Bioengineering. In 2017, she has been elevated IEEE Fellow “for contributions to energy-efficient computer architectures”. Her research focuses on computer architectures and Electronic Design Automation, with emphasis on power-aware design of embedded systems, design space exploration of energy-efficient computer architectures and application autotuning for manycore architectures and High-Performance Computing. She was Project Coordinator of three European projects: H2020-FET-HPC ANTAREX-671623 (2015-2018), FP7-2PARMA-248716 (2010-2013) and FP7-MULTICUBE-216693 (2008-2010). She is an active member of the scientific community and she regularly serves in several international program committees. She also organized 15 international conferences/workshops as Program Chair or General Chair. She is Associate Editor of ACM Trans. on Architecture and Code Optimization (TACO) and IEEE Trans. on Computers. She served as Independent Expert Reviewer for the European Commission and for several science foundations. Her scientific production consists of more than 160 publications.”
