SUMMARY:Hardware-Independent Implementation of the Particle-in-Cell Code W
 arpX, based on the AMReX Framework
DESCRIPTION:Minisymposium\n\nHardware-Independent Implementation of the Pa
 rticle-in-Cell Code WarpX, based on the AMReX Framework\n\nLehe, Almgren, 
 Amorim, Bell, Fedeli...\n\nWarpX is an electromagnetic Particle-In-Cell co
 de and is part of the U.S. Department of Energy Exascale Computing Project
 . WarpX is built on the AMReX framework, which includes not only tools for
  mesh refinement and domain decomposition, but also a portability layer fo
 r hardware-independent code. Thanks to this approach, WarpX can run on NVI
 DIA, AMD and Intel GPUs, as well as on multi-core CPUs, without the need t
 o duplicate the source code. During this presentation, we will give an ove
 rview of the hardware-independent approach in WarpX, and discuss some of t
 he encountered challenges and lessons learned during its implementation. <
 br />Supported by the Exascale Computing Project (17-SC-20-SC), a collabor
 ative effort of two U.S. Department of Energy organizations (Office of Sci
 ence and the National Nuclear Security Administration).\n\nDomain: CS and
