SUMMARY:HiPar20 – Introduction: Workshop on Hierarchical Parallelism for E
 xascale Computing
DESCRIPTION:Workshop\n\nHiPar20 – Introduction: Workshop on Hierarchical P
 arallelism for Exascale Computing\n\nRizzi, Hollman, Li, Howes\n\nHigh-Per
 formance Computing (HPC) platforms are evolving toward having fewer but mo
 re powerful nodes, driven by the increasing number of physical cores in mu
 ltiple sockets and accelerators. The boundary between nodes and networks i
 s starting to blur, with some nodes now containing tens of compute element
 s and memory subsystems connected via a memory fabric. The immediate conse
 quence is increasing complexity, due to ever more complex architecture (e.
 g., memory hierarchies), novel accelerator designs and energy constraints.
  Spurred largely by this trend, hierarchical parallelism is gaining moment
 um. This approach embraces the intrinsic complexity of current and future 
 HPC systems, rather than avoiding it, by exploiting parallelism at all lev
 els; compute, memory and network. This workshop focuses on hierarchical pa
 rallelism. It aims to bring together application, hardware and software pr
 actitioners proposing new strategies to fully exploit computational hierar
 chies, and includes examples to illustrate the benefits for achieving extr
 eme scale parallelism.\n\nTag: Extreme Scale Computing, Heterogeneous Syst
