SUMMARY:MS27 - HPC Challenges in Kinetic Simulations of Plasmas, Part II o
 f III: Particle-Based Approach
DESCRIPTION:Minisymposium\nPhysics\n\nRefactoring and Porting the Legacy O
 RB5 Gyrokinetic Electromagnetic Code on Hybrid Architectures\n\nGheller\n\
 nGyrokinetic codes in plasma physics need outstanding computational resour
 ces to solve increasingly complex problems, requiring he effective exploit
 ation of cutting edge HPC architectures. In this talk, we will focus on OR
 B5, a state-of-the-art, first-principles-based gyrokinetic code. ORB5 is a

 s with PIConGPU\n\nHuebl, Widera, Garten, Richard, Steiniger...\n\nPIConGP
 U is an open source, multi-platform particle-in-cell code scaling to the f
 astest supercomputers in the TOP500 list. We present the architecture, nov
 el developments, and workflows that enable high-precision, fast turn-aroun
 d computations on Exascale-machines. Furthermore, we present our strate...
 \n\n---------------------\nFrom Titan to Summit: Experience in Porting the
  XGC Gyrokinetic Code to Multi‐GPU Architecture\n\nEthier, Scheinber
 g, Abbott, Worley, D’Azevedo...\n\nThis presentation will discuss some of 
 the details in porting the gyrokinetic PIC code XGC to the new 200-PF &ldq
 uo;Summit” computer at the Oak Ridge Leadership Computing Facility (
 OLCF). Its multi-GPU node architecture allows for optimizations that were 
 not available on its predecessor, the &...\n\n---------------------\nHigh 
 Performance Geometric Electromagnetic PIC on Staggered Grids with WarpX an
 d AMReX\n\nAmeres, Kormann\n\nGyrokinetic Particle-In-Cell codes are a ver
 y popular tool for the simulation of highly magnetized plasmas in fusion r
 esearch. By the use of the gyrokinetic theory, which ultimately bases itse
 lf on a neatly chosen coordinate transformation, large scale differences i
