SUMMARY:POP and ChEESE - The Audit of SeisSol for Computational Earthquake
  Simulations with GPU-Aware MPI Communication for Local Time Stepping
DESCRIPTION:Minisymposium\n\nPOP and ChEESE - The Audit of SeisSol for Com
 putational Earthquake Simulations with GPU-Aware MPI Communication for Loc
 al Time Stepping\n\nGabriel, Dorozhinskii, Bader\n\nThe ChEESE CoE is an i
 nitiative to integrate HPC and data analysis across Solid Earth related di
 sciplines in Europe. One of its main goals is to prepare ten flagship code
 s for upcoming exascale environments. These codes cover important asp
 ects of geoscience, namely: computational seismology, magnetohydrodynamics
 , physical volcanology, and tsunami modeling. In collaboration w
 ith ChEESE, the CoE on "Performance Optimisation and Productivity" (POP) c
 onducted performance audits of all ChEESE codes. We will present the audit
  performed on SeisSol, software for computational earthquake simulations, 
 specifically on its GPU version with a focus on GPU-aware MPI communicatio
 n for Local and Global Time stepping schemes. We will discuss insight gain
 ed from the audit and outlined consequences to be drawn for further d
 evelopment and performance optimization.\n\nDomain: CS and Math, Emerging 
 Applications, Chemistry and Materials, Climate and Weather, Physics, Solid
  Earth Dynamics, Life Sciences, Engineering
