(CALL FOR PARTICIPATION) PAW-ATM: Parallel Applications Workshop, Alternatives To MPI+X

[Dan Bonachea]

 

https://go.lbl.gov/paw

Alternatives to MPI+X are worth exploring as programmer productivity becomes a major component of scientific time-to-solution. Alternatives include parallel programming languages (e.g. Chapel, Regent, Fortran 2018), general-purpose libraries (e.g. Charm++, COMPSs, HPX, Legion, UPC++), and domain-specific libraries (e.g. Arkouda, Dask, Spark). With many options to choose from, it can be difficult for programmers to know which alternative models are appropriate for their application and for programming model developers to understand the opportunities for improvement. 

Through discussion of specific applications, PAW-ATM brings together application experts and programming model developers to improve applications and models.
