We are excited to announce the 11th International Parallel Data Systems Workshop (PDSW'26), to be held in conjunction with SC26: The International Conference for High Performance Computing, Networking, Storage, and Analysis, in Chicago, IL. PDSW'26 builds upon the rich legacy of its predecessor workshops, the Petascale Data Storage Workshop (PDSW, 2006–2015) and the Data Intensive Scalable Computing Systems (DISCS, 2012–2015) workshop.

The increasing importance of efficient data storage and management continues to drive scientific productivity across traditional simulation-based HPC environments and emerging Cloud, AI/ML, and Big Data analysis frameworks. Challenges are compounded by the rapidly expanding volumes of experimental and observational data, the growing disparity between computational and storage hardware performance, and the rise of novel data-driven algorithms in machine learning. This workshop aims to advance research and development by addressing the most pressing challenges in large-scale data storage and processing.

We invite the community to contribute original research manuscripts that introduce and evaluate novel algorithms or architectures, share significant scientific case studies or workloads, or assess the reproducibility of previously published work. We emphasize the importance of community collaboration for problem identification, workload capture, solution interoperability, standardization, and shared tools. Authors are encouraged to provide comprehensive experimental environment details (software versions, benchmark configurations, etc.) to promote transparency and facilitate collaborative progress.

Template and Submission
-----------------------------

- A full paper up to 6 pages in length, excluding references, acknowledgements, and AD/AE appendices. Once anonymization is removed for camera ready submission, these limits must still be met. Please make sure that author names fit within the 6-page limit as well even though the submission should be double-anonymized.
- Artifact Description (AD) Appendix is mandatory and Artifact Evaluation (AE) Appendix is optional.
- Papers must adhere to the IEEE conference proceeding template available at: https://www.ieee.org/conferences/publishing/templates
- Papers will be reviewed double-blind. Author names and affiliations should NOT be included in the submitted paper.
- Submit your papers by July 31st, 2026, 11:59 PM AoE at https://submissions.supercomputing.org/

Reproducibility Initiative
-----------------------------

Aligned with the SC26 Reproducibility Initiative (https://sc26.supercomputing.org/program/papers/reproducibility-initiative/), we require detailed and structured artifact descriptions (AD) using the SC26 format (https://github.com/jennfshr/sc26-repro). The AD should include a field for one or more links to data (Zenodo, figshare, etc.) and code (Github, GitLab, Bitbucket, etc.) repositories. For the artifacts that will be placed in the code repository, we encourage authors to follow the PDSW 2026 Reproducibility Addendum (https://www.pdsw.org/pdsw26/PDSW2026ReproducibilityInitiativeAddendum.pdf) on how to structure the artifact, as it will make it easier for the reviewing committee and readers of the paper in the future.
