SUMMARY

As supercomputers become more and more powerful, the number and diversity of  
applications that can be tackled with these machines grows. Unfortunately, the  
architectural complexity of these supercomputers grows as well, with heterogeneous  
processors, multiple levels of memory hierarchy, and many ways to move data and  
synchronize between processors. The MPI+X programming model, use of which is  
considered by many to be standard practice, demands that a programmer be expert  
in both the application domain and the low-level details of the architecture(s)  
on which that application will be deployed, and the availability of such superhuman  
programmers is a critical bottleneck. Things become more complicated when evolution  
and change in the underlying architecture translates into significant re-engineering  
of the MPI+X code to maintain performance.

Numerous alternatives to the MPI+X model exist, and by raising the level of  
abstraction on the application domain and/or the target architecture, they offer  
the ability for “mere mortal” programmers to take advantage of the supercomputing  
resources that are available to advance science and tackle urgent real-world problems.  
However, compared to the MPI+X approach, these alternatives generally lack two things.  
First, they aren’t as well known as MPI+X and a domain scientist may simply not be  
aware of models that are a good fit to their domain. Second, they are less mature  
than MPI+X and likely have more functionality or performance “potholes” that need  
only be identified to be addressed.

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.

SCOPE AND AIMS

The PAW-ATM workshop is designed to be a forum for discussion of  
supercomputing-scale parallel applications and their implementation in programming  
models outside of the dominant MPI+X paradigm. Papers and talks will explore the  
benefits (or perhaps drawbacks) of implementing specific applications with  
alternatives to MPI+X, whether those benefits are in performance, scalability,  
productivity, or some other metric important to that application domain.  
Presenters are encouraged to generalize the experience with their application  
to other domains in science and engineering and to bring up specific areas of  
improvement for the model(s) used in the implementation.

In doing so, our hope is to create a setting in which application authors, language  
designers, and architects can present and discuss the state of the art in alternative  
scalable programming models, while also wrestling with how to increase their  
effectiveness and adoption. Beyond well-established HPC scientific simulations, we also  
encourage submissions exploring artificial intelligence, big data analytics,  
machine learning, and other emerging application areas.

Topics of interest include, but are not limited to:

- Novel application development using high-level parallel programming languages  
and frameworks

- Examples that demonstrate performance, compiler optimization, error checking,  
and reduced software complexity

- Applications from artificial intelligence, data analytics, bioinformatics, and  
other novel areas

- Performance evaluation of applications developed using alternatives to MPI+X  
and comparisons to standard programming models

- Novel algorithms enabled by high-level parallel abstractions

- Experience with the use of new compilers and runtime environments

- Libraries using or supporting alternatives to MPI+X

- Benefits of hardware abstraction and data locality on algorithm implementation

Papers that include description of applications that demonstrate the use of  
alternative programming models will be given higher priority.

SUBMISSIONS

Submissions are solicited in two tracks:

1. Full-length papers presenting novel research results:

- Full-length papers will be published in the workshop proceedings.  
Submitted papers must describe original work that has not appeared in, nor is  
under consideration for another conference or journal. Papers shall be eight  
(8) pages minimum and not exceed ten (10) pages including text, figures,  
and non-AD appendices, but excluding bibliography and acknowledgments.

PAW-ATM follows the reproducibility initiative of SC24. Submissions shall include  
an Artifact Description (AD) appendix. The appendix pages related to the  
reproducibility initiative dependencies are not included in the page count.  
See [The 7th Annual Parallel Applications Workshop, Alternatives To MPI+X (PAW-ATM) by sourceryinstitute](https://sourceryinstitute.github.io/PAW/) for further details.

1. User experience abstracts:

- Abstracts will be evaluated separately and will not be included in the published  
proceedings. Submissions in this track will include a title and a 1-page abstract  
and the content may include any combination of novel and/or previously published  
work that is relevant to the workshop’s scope.
