SUMMARY:MS41 - Adaptive Mesh Refinement in the Era of Platform Heterogenei
 ty, Part I of II
DESCRIPTION:Minisymposium\nComputer Science and Applied Mathematics, Physi
 cs, Solid Earth Dynamics\n\nDesign of Communication Patterns for Forest-of
 -Octrees AMR Codes\n\nBurstedde, Holke\n\nWe will discuss symmetric and no
 n-symmetric communication patterns that arise in forest-of-octrees paralle
 l adaptive mesh refinement (AMR). Here, symmetry means that each receiver 
 is also a sender to the sending process, and that both messages may overla
 p using asynchronous calls. One algorithm that...\n\n---------------------
 \nPhase Asynchronous AMR Execution on Heterogeneous Architectures\n\nUnat\
 n\nIn the Adaptive Mesh Refinement (AMR) context, porting an application f
 rom synchronous to fully asynchronous execution increases application perf
 ormance but also requires tremendous programming effort because the progra
 mmer has to explicitly specify data dependencies, schedule a grid for comp
 utation...\n\n---------------------\nThe RAMSES Code, Next Generation\n\nT
 eyssier, Potter\n\nWe present our strategy to implement the next generatio
 n of the RAMSES code, a community code with adaptive mesh refinement for a
 strophysical fluid flows. Our current prototype is based on a global multi
 -level Cartesian grid indexing scheme with a software cache. The MPI and O
 penMP backend is hidden...\n\n---------------------\nPerformance Portabili
 ty in AMR: Leveraging the LLVM Compiler Infrastructure in AMR Frameworks\n
 \nWahib\n\nAMR frameworks are no exception for the performance portability
  challenge in HPC. Several approaches can be used for supporting an accept
 able level of performance portability. In this talk we focus on one of tho
 se approaches: using a compiler-based approach. We leverage the capability
  of the LLVM co...\n
