SUMMARY:Energy-Efficient GPU Computing
DESCRIPTION:Ben van Werkhoven (Leiden Institute of Advanced Computer Scien
 ce (LIACS), Netherlands eScience Center) and Alessio Sclocco, Stijn Helden
 s, and Floris-Jan Willemsen (Netherlands eScience Center)\n\nEnergy effici
 ency has become a critical concern in High Performance Computing (HPC) and
  supercomputing, especially with the advent of exascale systems. The incre
 asing demand for computational power and the associated energy consumption
  have led to a growing need for optimization techniques to reduce power co
 nsumption. GPUs, now the primary source of compute power in exascale super
 computers, contribute significantly to the overall energy expenditure of t
 hese systems. Consequently, the development and implementation of energy-e
 fficient strategies for GPU applications are essential to reduce the envir
 onmental impact and operational costs of HPC facilities.\n\nThis tutorial 
 offers a comprehensive introduction to energy-efficient computing in the c
 ontext of HPC, focusing on GPU applications. As a participant, you will ga
 in insight into code optimization techniques that improve energy efficienc
 y, automatically explore performance-energy trade-offs using Kernel Tuner,
  dive into mixed-precision techniques, and learn how to write clean code f
 or reduced-precision arithmetic on GPUs.\n\nFinally, the tutorial addresse
 s GPU clock frequency optimization as a means to improve energy efficiency
 , including how to find the optimal core clock frequency range. The hands-
 on approach of this tutorial enables participants to acquire valuable know
 ledge and practical experience in energy-efficient computing, essential fo
 r advancing environmentally sustainable and cost-effective HPC and superco
 mputing solutions.\n\nTag: Accelerators, Energy Efficiency\n\nRegistration
