DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: As HPC approaches exascale computing, processor and node architectures are diverging rapidly, between distinct vendors and even across generations from a given vendor.  This challenges programming models that cannot expose intra-node locality or rapidly adapt to novel processor architectures.  It also challenges end-users by requiring them to modify their programs when moving between systems.=0A=0AOur emerging technology exhibit introduces Chapel's hierarchical locales—a programming language abstraction that facilitates rapid adaptation to such architectural changes.  Hierarchical locales differ from previous approaches in that users can provide their own architectural models to the compiler, providing the mapping from high-level parallel algorithms using standard Chapel concepts down to target systems.  Moreover, hierarchical locales impose fewer semantic restrictions than previous approaches.=0A=0AIn this exhibit, we introduce the notion of hierarchical locales, explain how they are deployed and used in the Chapel implementation today, and report on our support for NUMA nodes and Intel MIC.
