DESCRIPTION:By : Sandhya Dwarkadas - University of Rochester (invited prof
 essor at EPFL)\nVideo of the talk\n\nAbstract :\nRecognizing that applicat
 ions are rarely executed in isolation today\, I will discuss some practica
 l challenges in making best use of available hardware and our approach to 
 addressing these challenges. I will describe two independent and complemen
 tary control mechanisms using low-overhead hardware performance counters t
 hat we have developed: a sharing- and resource-aware mapper (SAM) to effec
 t task placement with the goal of localizing shared data communication and
  minimizing resource contention based on the offered load\; and an applica
 tion parallelism manager (MAP) that controls the offered load with the goa
 l of improving system parallel efficiency. Our results emphasize the need 
 for low-overhead monitoring of application behavior under changing environ
 mental conditions in order to adapt to environment and application behavio
 r changes. If time permits\, I will also outline additional work on memory
  management design that eliminates address translation redundancy via appr
 opriate sharing.\n\nBio :\nSandhya Dwarkadas is the Albert Arendt Hopeman 
 Professor and Chair of Computer Science at the University of Rochester\, w
 ith a secondary appointment in Electrical and Computer Engineering. She is
  currently on sabbatical as an invited professor at EPFL. She was named an
  IEEE fellow in 2017 for her contributions to shared memory and reconfigur
 ability. Her research is targeted at both the hardware and software layers
  of computing systems and especially at the boundary\, with a particular f
 ocus on the challenges of making coordination and communication efficient 
 in parallel and distributed systems. She is co-inventor on 12 granted U.S.
  patents. She was program chair for ASPLOS (International Conference on Ar
 chitectural Support for Programming Languages and Operating Systems) 2015.
  She is currently a board member on Computing Research Association's Commi
 ttee on the Status of Women in Computing Research (CRA-W).\n\nMore informa
