SUMMARY:Problem Solving Environment and Compiler Optimizations for High Pe
 rformance Particle-Mesh Numerical Simulations
DESCRIPTION:Workshop\n\nProblem Solving Environment and Compiler Optimizat
 ions for High Performance Particle-Mesh Numerical Simulations\n\nKhouzami\
 n\nWe present OpenPME (Open Particle-Mesh Environment), a Problem Solving 
 Environment (PSE)  which provides a Domain Specific Language (DSL) built a
 top a domain model general enough to write numerical simulations in scient
 ific computing using particle-mesh abstractions. This helps to close the p
 roductivity gap in HPC applications and effectively lowers the programming
  barrier to enable the smooth implementation of scalable simulations. Open
 PME programs are lowered to generate high-performant C++ code through a se
 quence of compiler model-to-model transformations. We also introduce a mod
 el-based autotuning approach of discretization methods for OpenPME compile
 r. We evaluate the autotuner in two diffusion test cases and the results s
 how that we consistently find configurations that outperform those found b
 y state-of-the-art general-purpose autotuners.\n\nSession Format: Recorded
