SUMMARY:PAW-ATM 2021:  The 4th Annual Parallel Applications Workshop, Alte
 rnatives to MPI+X
DESCRIPTION:Workshop\n\nPAW-ATM 2021:  The 4th Annual Parallel Application
 s Workshop, Alternatives to MPI+X\n\nMorris, Badia, Ferguson\n\nSupercompu
 ters get faster and more complex every year.  MPI, long the dominant model
  for distributed computation, has adapted by combining with models for int
 ra-node parallelism (e.g. OpenMP, CUDA). These MPI+X hybrids offer perform
 ance but demand significant programmer effort to write, debug and tune app
 lications.\n\nAlternatives to MPI+X are worth exploring as programmer prod
 uctivity becomes a major component of the “time to science”.  Some alterna
 tives are parallel programing languages (e.g. Chapel, Regent, Fortran 2018
 ), general purpose libraries (e.g. Charm++, COMPSs, HPX, Legion, UPC++), a
 nd domain specific (e.g. Arkouda, Dask, Spark).  None are as widely used a
 s MPI+X, making it hard for programmers to judge if alternative models are
  appropriate for their application and for programming model developers to
  understand where opportunities for improvement lie.\n\nThrough discussion
  of specific applications, PAW-ATM brings together application experts and
  programming model developers to better understand available alternatives 
 and how they may be improved.\n\nTag: Online Only, Applications, Extreme S
 cale Computing, Heterogeneous Systems, Parallel Programming Languages and
