DESCRIPTION:By Katzalin Olcoz Herrero\, Associate Professor at the Departm
 ent of Computer Architectures and Engineering in Complutense University of
  Madrid\n\nKatzalin Olcoz received a Ph.D. degree in Physics in 1997 from 
 the Complutense University of Madrid (UCM). She has been Associate Profess
 or in the Department of Computer Architecture and System Engineering of th
 e Complutense University since 2000. She has been Head of the Department o
 f Computer Architecture and System Engineering and she has also collaborat
 ed 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 co
 mputer architecture and design automation from high-level specifications. 
 Her current research addresses emerging issues related to asymmetric proce
 ssors\, heterogeneous systems and energy-aware computing\, with a special 
 emphasis on the interaction between the system software and the underlying
  architecture.  \nAbstract\nOver the last years\, heterogeneity has becom
 e one of the main concepts explored by computer architects to improve perf
 ormance while keeping power and energy in the face of continued technology
  miniaturization (as predicted by Moore's Law) and slowed supply voltage r
 eduction (i.e. the end of Dennard scaling).\nHeterogeneity ranges from het
 erogeneous configurations in datacenters to processors with on-chip hardwa
 re accelerators\, hybrid CPU/GPU platforms\, single-ISA asymmetric multico
 res and multi-ISA heterogeneous multicores.\nDeveloping 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 softw
 are stack. We will focus on the collaboration among the programming models
 \, runtimes and libraries.\nIn this talk I will show you some of my recent
  work on different ways of dealing with the heterogeneity of the system fo
 r the efficient execution of task parallel applications on ARM asymmetric 
 big.LITTLE platforms. First\, the library will take care of asymmetry\, pr
 esenting a homogeneous system to the runtime. Then\, it will be the runtim
 e who will deal with the asymmetry of the cores.\n
