PAW-ATM 2026: Parallel Applications Workshop, Alternatives To MPI+X

PAW-ATM 2026: Parallel Applications Workshop, Alternatives To MPI+X
Co-located at Supercomputing 2026
November 15–20, 2026

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.

Topics of Interst

• 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

Submission guidelines: 
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, acknowledgments and AD/AE appendices.

PAW-ATM follows the reproducibility initiative of SC26. Submissions shall include an Artifact Description (AD) appendix, and may optionally include an Artifact Evaluation (AE) appendix.

See https://sourceryinstitute.github.io/PAW/ 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.
