Summary
-------

Architectural hierarchy and heterogeneity makes programming supercomputers
challenging.  In practice, HPC applications tend to be written using a mix of
programming models -- like C++, MPI, CUDA, and/or OpenMP -- each of which is
becoming more complex over time.  This negatively impacts the costs of
developing, maintaining, and porting HPC applications.  
 
Meanwhile, alternative HPC programming models strive to improve things by
raising the level of abstraction; incorporating modern features; and/or
leveraging the respective strengths of programmers, compilers, and runtimes.
These alternatives take the form of new languages (e.g., Chapel, Regent,
XcalableMP), frameworks for large-scale data science (e.g., Arkouda, Dask,
Spark), or extensions to existing languages (e.g., Charm++, COMPSs, Fortran,
Legion, UPC++).

PAW-ATM is a forum for discussing HPC applications written in alternatives to
MPI+X.  Its goal is to bring together application experts and proponents of
high-level languages to present concrete example uses of such alternatives,
describing their benefits and challenges.
