The 8th Annual Parallel Applications Workshop, Alternatives To MPI+X...

SUMMARY

As supercomputers become more and more powerful, the number and diversity of
applications that can be tackled with these machines grow. 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 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, figures, and
non-AD/AE appendices, but excluding bibliography and acknowledgments.

PAW-ATM follows the reproducibility initiative of SC25. Submissions shall
include an Artifact Description (AD) appendix, and may optionally include an
Artifact Evaluation (AE) appendix.

Authors should include a draft of the AD/AE appendices with the initial
manuscript PDF submission. You will have the opportunity to revise the
appendix before its final submission. See
The 8th Annual Parallel Applications Workshop, Alternatives To MPI+X (PAW-ATM) by sourceryinstitute for further details.

2. User experience abstracts:

Abstracts will be evaluated separately and will not be included in the
published proceedings. Submissions in this track include a title and 1-4
pages abstract. The content may include any combination of novel and/or
previously published work that is relevant to the workshop’s scope. Content
that highlights the experiences of users of alternatives of MPI, and their
applications, will be prioritized within this submission category.

Abstracts may optionally include AD/AE appendices, not included in the
abstract page count, but such appendices will not be evaluated and no badges
will be awarded.
