Hello Chapel Community,
This year's PAW-ATM (Parallel Applications Workshop, Alternatives to MPI+X) will be held at SC23 in Denver on November 13. PAW-ATM focuses on applications that uses alternatives to MPI-X programming paradigm, including Chapel. This year's agenda has 2 papers that uses Chapel, among many other talks and papers on other technologies.
Please see the workshop website or the more detailed Call for Participation below.

Thanks,
Engin Kayraklioglu, on behalf of the PAW-ATM Organizing Committee
Call for Participation PAW-ATM 2023:
Parallel Applications Workshop, Alternatives To MPI+X
Held in conjunction with SC23, Denver, CO
November 13, 2023
9:00am - 5:30pm (MST)
Room 702 / Hybrid Event
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.
