                Call for Papers PAW-ATM 2023:
 Parallel Applications Workshop, Alternatives To MPI+X

       Held in conjunction with SC23, Denver, CO

Submissions deadline: July 24, 2023
Notification to authors: August 31, 2023
Workshop date: November 13, 2023  (updated)



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

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.


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

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


Submissions are solicited in 2 categories:

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, appendices, and
figures, but excluding bibliography and acknowledgments. Submissions shall
not exceed twelve (12) pages total under any circumstance.

2) Extended abstracts summarizing preliminary/published results:

Extended abstracts will be evaluated separately and will not be included in
the published proceedings; they are intended to propose timely
communications of novel work that will be formally submitted elsewhere at a
later stage, and/or of already published work that would be of interest to
the PAW-ATM audience in terms of topic and timeliness.  Extended abstracts
shall not exceed four (4) pages.
