Katzalin Olcoz Associate Professor Department of Computer Architecture and System Engineering Complutense University of Madrid Tuesday, October 24 at 4pm Faculty Host: Ayse Coskun Light refreshments will be available at 3:45 pm outside of PHO 339 Title: Performance and energy efficiency on heterogeneous platforms Abstract Over the last few years, heterogeneity has  become one of the main concepts explored by computer architects to improve performance while keeping power, energy and thermal-efficiency in the face of continued technology miniaturization (as predicted by Moore's Law) and slowed supply voltage reduction (i.e. the end of Dennard scaling). Heterogeneity ranges from heterogeneous configurations in data centers to processors with on-chip hardware accelerators, hybrid CPU/GPU platforms, single-ISA asymmetric multicores and multi-ISA heterogeneous multicores. Developing software for such systems in a way that all the different resources are efficiently used is complex and requires collaboration among the different levels of the software stack. We will focus on the collaboration among the programming models, runtimes and libraries. In this talk I will discuss some of my recent work on different ways of handling heterogeneity of the system for efficient execution of task parallel applications on ARM asymmetric big.LITTLE platforms. First, the library takes care of the asymmetry, presenting an homogeneous system to the  runtime system. Then, runtime system further addresses the asymmetry of the cores. Bio Katzalin Olcoz received a Ph.D. degree in Physics in 1997 from the Complutense University of Madrid (UCM). She has been Associate Professor in the Department of Computer Architecture and System Engineering of the Complutense University since 2000. She has been Head of the Department of Computer Architecture and System Engineering and she has also collaborated with the Spanish R&D Agency. Within the ARTECS group of the Complutense University, she has been involved in several projects in the field of computer architecture and design automation from high-level specifications. Her current research addresses emerging issues related to asymmetric processors, heterogeneous systems and energy-aware computing, with a special emphasis on the interaction between the system software and the underlying architecture.
