DESCRIPTION:By: Gilles Muller - LIP6 INRIA   Abstract:\nComplex embedded s
 ystems today commonly involve a mix of real-time and best-effort applicati
 ons. The recent emergence of small low-cost commodity UMA multicore proces
 sors raises the possibility of running both kinds of applications on a sin
 gle machine\, with virtualization ensuring that the best-effort applicatio
 ns cannot steal CPU cycles from the real-time applications. Nevertheless\,
  memory contention can introduce other sources of delay\, that can lead to
  missed deadlines. In this research report\, we present a combined offline
 /online memory bandwidth monitoring approach. Our approach estimates and l
 imits the impact of the memory contention incurred by the best-effort appl
 ications on the execution time of the real-time application. We show that 
 our approach is compatible with the hardware counters provided by current 
 small commodity multicore processors. Using our approach\, the system desi
 gner can limit the overhead on the real-time application to under 5% of it
 s expected execution time\, while still enabling progress of the best-effo
 rt applications.  \n\nBio:\nGilles Muller received the Ph.D. degree in 19
 88 from the University of  Rennes I\, and the Habilitation a Diriger des 
 Recherches degree in 1997 from the University of Rennes I. After having be
 en a researcher at INRIA and a Professor at the Ecole des Mines de Nantes\
 , he is currently a senior research scientist at Inria Paris-Rocquencourt 
 and the head of the Whisper group. His research interests include the deve
 lopment of methodologies based on domain-specific languages for the struct
 uring of infrastructure softwares. He is one of the designers of the Cocci
 nelle tool. \n \nGilles Muller was the PC Chair of EuroSys 2010 and PLOS
  2010. He was  involved in more than 50 program committees of internation
 al workshops and conferences such as EuroSys\, ASPLOS\, DSN\, SRDS\, PLOS\
 , VEE and the EuroSys prize for the best PhD thesis. Gilles Muller is a me
 mber of the Eurosys steering committee and was the vice chair of the ACM/S
 IGOPS from July 2003 to July 2007.\n\n\n\nMore information
