SUMMARY:Extensions to the SENSEI In situ Framework for Heterogeneous Archi
 tectures
DESCRIPTION:Burlen Loring and Gunther H. Webber (Lawrence Berkeley Nationa
 l Laboratory (LBNL)); E. Wes Bethel (San Francisco State University, Lawre
 nce Berkeley National Laboratory (LBNL)); and Michael W. Mahoney (Lawrence
  Berkeley National Laboratory (LBNL); University of California, University
  of California, Berkeley)\n\nThe presence of GPUs and accelerators in rece
 nt super computing\nsystems, so called heterogeneous architectures, has le
 ad to increased\ncomplexity in execution environments and programming mode
 ls\nas well as deeper memory hierarchies on these systems. In this\nwork w
 e discuss challenges that arise in in situ code coupling on\nheterogeneous
  architectures. We present data and execution model\nextensions to the SEN
 SEI in situ framework targeted at effective use\nof systems with heterogen
 eous architectures. We use the new data\nand execution model extensions in
  SENSEI to investigate a number\nof in situ placement and execution config
 urations and analyze the\nimpact these choices have on overall performance
