DESCRIPTION:Workshop\nHeterogeneous Systems, Performance, Workshop Reg Pas
 s\n\nHigh-Performance Molecular Dynamics Simulation for Biological and Mat
 erials Sciences: Challenges of Performance Portability\n\nSedova, Eblen, B
 udiardja, Tharrington, Smith\n\nHighly-optimized parallel molecular dynami
 cs programs have, in recent years, allowed researchers to achieve ground-b
 reaking results in biological and materials sciences. This type of perform
 ance has come at the expense of portability: a significant effort is requi
 red for performance optimization on ...\n\n---------------------\nHeteroge
 neous CPU-GPU Execution of Stencil Applications\n\nSiklosi, Reguly, Mudali
 ge\n\nHeterogeneous computer architectures are now ubiquitous in high perf
 ormance computing; the top 7 supercomputers are all built with CPUs and ac
 celerators. Portability across different CPUs and GPUs is becoming paramou
 nt, and heterogeneous scheduling of computations is also of increasing int
 erest to m...\n\n---------------------\nPerformance Portability of an Unst
 ructured Hydrodynamics Mini-Application\n\nLaw, Kevis, Powell, Dickson, Ma
 heswaran...\n\nIn this work we study the parallel performance portability 
 of BookLeaf: a recent 2D unstructured hydrodynamics mini-application. The 
 aim of BookLeaf is to provide a self-contained and representative testbed 
 for exploration of the modern hydrodynamics application design-space.\n\nW

  Challenges for Fortran Applications\n\nHsu, Neill, Schoonover, Jibben, Ca
 rlson...\n\nThis project investigates how different approaches to parallel
  optimization impact the performance portability for Fortran codes. In add
 ition, we explore the productivity challenges due to the software tool-cha
 in limitations unique to Fortran. For this study, we build upon the Trucha
 s software, a me...\n\n---------------------\nDelivering Performance-Porta
 ble Stencil Computations on CPUs and GPUs Using Bricks\n\nZhao, Williams, 
 Hall, Johansen\n\nAchieving high performance on stencil computations poses
  a number of challenges on modern architectures. The optimization strategy
  varies significantly across architectures, types of stencils, and types o
 f applications. The standard approach to adapting stencil computations to 
 different architecture...\n\n---------------------\nEvaluating the Impact 
 of Proposed OpenMP 5.0 Features on Performance, Portability, and Productiv
 ity\n\nPennycook, Sewall, Hammond\n\nWe investigate how specialization mec
 hanisms proposed for OpenMP 5.0 -- specifically, the metadirective and dec
 lare variant directives -- may be deployed in a real-life code, using the 
 miniMD benchmark from the Mantevo suite.\n\nAdditionally, we develop an Op
 enMP 4.5 implementation of miniMD that achi...\n\n---------------------\nE
 ffective Performance Portability\n\nHarrell, Kitson, Bird, Pennycook, Sewa
 ll...\n\nExascale computing brings with it diverse machine architectures a
 nd programming approaches which challenge application developers. Applicat
 ions need to perform well on a wide range of architectures while simultane
 ously minimizing development and maintenance overheads. In order to allevi
 ate these cos...\n\n---------------------\nIntroduction - International Wo
 rkshop on Performance, Portability, and Productivity in HPC (P3HPC)\n\nDoe
 rfler, Neely, Pennycook, O'Brien\n\nThe ability for applications to achiev
 e both portability and high performance across computer architectures rema
 ins an open challenge.  It is often unrealistic or undesirable for develop
 ers to maintain separate implementations for each target architecture, yet
  in many cases, achieving high performan...\n\n---------------------\nP3HP

 nce on-node computation, memory capacity, memory bandwidth, interconnect b
 andwidth, power, and cost for specific computational workloads. For many a
