**************************************************************** Call for Participation PAW-ATM 2024: Parallel Applications Workshop, Alternatives To MPI+X

Held in conjunction with SC24, Atlanta, GA

November 17, 2024 9:00am - 5:30pm (EST) Room B306 / Hybrid Event

Alternatives to MPI+X are worth exploring as programmer productivity becomes a major component of the time to science. 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 is hard 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. WORKSHOP PROGRAM
