The current trend to move from homogeneous to heterogeneous multi-core (HetCMP) systems promises further performance and energy-efficiency benefits. A typical HetCMP system includes two distinct types of cores, such as high performance sophisticated ("large") cores and simple low-power ("small") cores. In those heterogeneous platforms, execution phases of application threads that are CPU-intensive can take best advantage of large cores, whereas I/O or memory intensive execution phases are best suited and assigned to small cores. However, it is crucial that the assignment of threads to cores satisfy both the computational and memory bandwidth constraints of the threads.

In this talk we will present current work on scheduling and allocation of threads in HetCMP, with soft-real-time and no real-time constraints as well as some open problems in the field.

Bio
Daniel Mosse is Professor and Chair of the Computer Science Department at the University of Pittsburgh. The current major thrusts of his research are real-time and embedded systems, power management issues, and networks (wireless and security), bridging the gap between the operating systems and networking research fields. He has published approximately 200 papers worldwide in these topics. Typically funded by NSF and DARPA, his projects combine theoretical results and actual implementations. He received a BS in Mathematics from the University of Brasilia in 1986, and MS and PhD degrees in Computer Science from the University of Maryland in 1990 and 1993, respectively. Dr. Mosse received the Provost's Innovation in Education Grant/Award in 2007 for redesigning the Introductory Programming course for non-majors. He received the Tina and David Bellet Teaching Excellence Award in 2006 (One of two among over 500 faculty members in the School of Arts and Sciences). Dr. Mosse has served on PCs and as PC chair for most major IEEE- and ACM-sponsored real-time conferences. In 2011, he was co-chair of the International Green Computing Conference and General Co-Chair for the International conference on Embedded and Real-Time Computing Systems.
