SUMMARY:Performance Measurement on Heterogeneous Processors with PAPI
DESCRIPTION:Vincent Weaver and Willow Cunningham (University of Maine)\n\n
 Modern computer processors improve their computing power by having multipl
 e cores. Traditionally these cores were homogeneous: many identical cores 
 with the same capabilities. Instead it is possible to create processors th
 at have heterogeneous (or hybrid) cores, where the various cores have diff
 ering capabilities. This can lead to energy savings and other efficiencies
 , but complicates performance analysis. Heterogeneous cores have been comm
 on for years in embedded ARM processors; recently support has appeared in 
 x86 desktop processors as well. It is likely that before long server and h
 igh-performance systems will also gain hybrid cores.\n\nWe look at current
  Linux support for heterogeneous processors and detail the various problem
 s encountered when adding support for  them to the PAPI performance measur
 ement library.\n\nTag: Debugging and Correctness Tools, Performance Evalua
 tion and/or Optimization Tools\n\nRegistration Category: Workshop Reg Pass
 \n\nSession Chairs: David Boehme (Lawrence Livermore National Laboratory (
 LLNL)); Kate Isaacs (University of Utah); Carmen Navarrete (Leibniz Superc
 omputing Centre (LRZ)); and Emmanuelle Saillard (CEA, DAM, DIF)\n\n
