SUMMARY:Invited Talk 1:  The Legacy of ECP Software Efforts, Realized, and
  to Come
DESCRIPTION:Michael A. Heroux (Sandia National Laboratories)\n\nThe US Dep
 artment of Energy (DOE) Exascale Computing Project (ECP) is coming to an e
 nd.  But the impact of the project is just beginning.  ECP has produced do
 zens of GPU-enabled, scalable application codes and dozens of GPU-capable 
 libraries and tools that underpin these applications.  The experiences and
  software capabilities coming out of ECP are ready for further leveraging 
 within DOE and beyond.  ECP outcomes demonstrate that the opportunity for 
 impact on science and engineering computations is exceptional.  Across the
  board, ECP applications realized improvements of 100 times or more in per
 formance and scalability, leading to similar orders of scientific impact. 
  Furthermore, this impact comes primarily from adapting algorithms and sof
 tware to exploit GPU devices from NVIDIA, AMD, and Intel through performan
 ce portability layers.  While ECP focused on expanding capabilities for la
 rge systems, the same technical advances are directly translatable to migr
 ating existing applications to smaller systems.  For example, a problem th
 at presently requires a CPU-based cluster can realize similar performance 
 on desktop systems leveraging GPUs, greatly reduce energy and infrastructu
 re costs.    As the energy costs of HPC projects become an increasing conc
 ern, accelerated (GPU) devices become the path to increased efficiency but
  only if our HPC software stacks can deliver the performance potential.  T
 he true legacy of ECP will be how it advanced the development of applicati
 on codes and established a stack of libraries and tools to be leveraged by
  the broader HPC community.  ECP provides a foundation for transforming HP
 C applications to realize their performance potential on GPUs and future a
 ccelerated devices.\n\nTag: Algorithms, Heterogeneous Computing, Large Sca
