SUMMARY:The 6th Annual Parallel Applications Workshop, Alternatives to MPI
 +X (PAW-ATM)
DESCRIPTION:Karla Vanessa Morris Wright (Sandia National Laboratories); El
 liott Slaughter (SLAC National Accelerator Laboratory); Engin Kayraklioglu
  (Hewlett Packard Enterprise (HPE)); Irene Moulitsas (Cranfield University
 , England); Daniele Lezzi (Barcelona Supercomputing Center (BSC)); and Wil
 liam Long (Hewlett Packard Enterprise (HPE))\n\nSupercomputers get faster 
 and more complex every year. MPI, long the dominant model for distributed 
 computation, has adapted by combining with models for intra-node paralleli
 sm (e.g. OpenMP, CUDA). These MPI+X hybrids offer performance but demand s
 ignificant programmer effort to write, debug and tune applications.\n\nAlt
 ernatives to MPI+X are worth exploring as programmer productivity becomes 
 a major component of the time to science. Alternatives include parallel pr
 ograming languages (e.g. Chapel, Regent, Fortran 2018), general purpose li
 braries (e.g. Charm++, COMPSs, HPX, Legion, UPC++), and domain specific li
 braries (e.g. Arkouda, Dask, Spark). With many options to choose from, it 
 is hard for programmers to know which alternative models are appropriate f
 or their application and for programming model developers to understand th
 e opportunities for improvement.\n\nThrough discussion of specific applica
 tions, PAW-ATM brings together application experts and programming model d
 evelopers to improve applications and models.\n\nTag: Accelerators, Artifi
