SUMMARY:ECP WDMApp: An Exascale Software Project
DESCRIPTION:Minisymposium\n\nECP WDMApp: An Exascale Software Project\n\nE
 thier, Germaschewski, Suchyta, D'Azevedo, Allen...\n\nWhile the most visib
 le achievement of the US DOE Exascale Computing Project will certainly be 
 the roll out of 3 exascale computers, the ECP scientists themselves are pr
 imarily involved in software and algorithms development aimed at securing 
 a diverse set of exascale-capable codes ready to run at scale on day one. 
 Among these, the magnetic fusion Whole-Device Modeling Application (WDMApp
 ) is particularly challenging as it tries to couple very complex gyrokinet
 ic codes that have been developed separately from each other.  The ul
 timate goal, however, is to build an exascale framework for coupling many 
 more fusion codes that will together form a unique whole-device simulation
  tool for magnetic confinement fusion devices. This presentation will desc
 ribe the software developments involved in making this framework, some of 
 them being driven by the challenges of exascale. In so doing, we leve
 rage as much as possible the numerical tools and libraries being developed
  by the ECP software technology and co-design projects.\n\nDomain: CS and 
 Math, Physics
