SUMMARY:Extensions to the SENSEI In situ Framework for Heterogeneous Archi
 tectures
DESCRIPTION:Workshop\n\nBurlen Loring and Gunther H. Webber (Lawrence Berk
 eley National Laboratory (LBNL)); E. Wes Bethel (San Francisco State Unive
 rsity, Lawrence Berkeley National Laboratory (LBNL)); and Michael W. Mahon
 ey (Lawrence Berkeley National Laboratory (LBNL); University of California
 , University of California, Berkeley)\n\nThe presence of GPUs and accelera
 tors in recent super computing\nsystems, so called heterogeneous architect
 ures, has lead to increased\ncomplexity in execution environments and prog
 ramming models\nas well as deeper memory hierarchies on these systems. In 
 this\nwork we discuss challenges that arise in in situ code coupling on\nh
 eterogeneous architectures. We present data and execution model\nextension
 s to the SENSEI in situ framework targeted at effective use\nof systems wi
 th heterogeneous architectures. We use the new data\nand execution model e
 xtensions in SENSEI to investigate a number\nof in situ placement and exec
 ution configurations and analyze the\nimpact these choices have on overall
  performance.\n\nTag: Data Analysis, Visualization, and Storage, Large Sca
