keynote speaker

PDSW 20 is proud to announce that Nitin Agrawal, ThoughtSpot, will be our keynote speaker. He will highlight potential challenges, recent work, and research opportunities, in designing systems to handle this discrepancy between data generation and access. Please watch for further details here.

Nitin Agrawal is a Principal Engineer at ThoughtSpot working on search infrastructure and in-memory databases. His past work experience is broadly in systems, with an emphasis on storage, mobile, and distributed systems, and has received multiple best–paper awards, led to commercial & academic impact, an outstanding patent award, and widespread media attention. He served as the program-committee chair for USENIX FAST ’18, HotStorage '16, and earned his doctorate in Computer Science from the University of Wisconsin - Madison.

We are pleased to announce the 5th International Parallel Data Systems Workshop (PDSW’20). PDSW'20 will be hosted in conjunction with SC20: The International Conference for High Performance Computing, Networking, Storage and Analysis.

Efficient data storage and data management are crucial to scientific productivity in both traditional simulation-oriented HPC environments and Big Data analysis environments. This issue is further exacerbated by the growing volume of experimental and observational data, the widening gap between the performance of computational hardware and storage hardware, and the emergence of new data-driven algorithms in machine learning.

The goal of this workshop is to facilitate research that addresses the most critical challenges in scientific data storage and data processing. We therefore encourage the community to submit original manuscripts that:

  • introduce and evaluate novel algorithms or architectures,
  • inform the community of important scientific case studies or workloads, or
  • validate the reproducibility of previously published work

Special attention will be given to issues in which community collaboration is crucial for problem identification, workload capture, solution interoperability, standardization, and shared tools. We also strongly encourage papers to share complete experimental environment information (software version numbers, benchmark configurations, etc.) to facilitate collaboration.

Topics of interest include the following:

  • Scalable architectures for data storage, archival, and virtualization
  • Performance benchmarking, resource management, and workload studies
  • Programmability of storage systems
  • Parallel file systems, metadata management, and complex data management
  • Alternative data storage models, including object stores and key-value stores
  • Programming models and frameworks for data intensive computing
  • Techniques for data integrity, availability, reliability, and fault tolerance
  • Productivity tools for data intensive computing, data mining, and knowledge discovery
  • Application of emerging big data frameworks towards scientific computing and analysis
  • Enabling cloud and container-based models for scientific data analysis
  • Data filtering/compressing/reduction techniques
  • Tools and techniques for managing data movement among compute and data intensive components
  • Integrating computation into the memory and storage hierarchy to facilitate in-situ and in-transit data processing



CALL FOR PAPERS - updated with new submission deadlines!

Regular paper SUBMISSIONS

All papers will be evaluated by a competitive peer review process under the supervision of the workshop program committee. Selected papers and associated talk slides will be made available on the workshop web site. The papers will also be published by the IEEE TCHPC.

Authors of regular papers are strongly encouraged to submit Artifact Description (AD) Appendices that can help to reproduce and validate their experimental results. While the inclusion of the AD Appendices is optional for PDSW’20, submissions that are accompanied by AD Appendices will be given favorable consideration for the PDSW Best Paper award. PDSW’20 follows the SC20 reproducibility and transparency initiative. For Artifact Description (AD) Appendices, we will use the format of the SC20 for PDSW'20 submissions. 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'20 Artifact Packaging Guidelines on how to structure the artifact, as it will make it easier to the reviewing committee and readers of the paper in the future.

Submit a not previously published paper as a PDF file, indicate authors and affiliations. Papers must be up to 5 pages, not less than 10 point font and not including references and optional reproducibility appendices. Papers must use the IEEE conference paper template available at: https://www.ieee.org/conferences/publishing/templates.html.

* Submissions must be in the IEEE conference format

Work In Progress (WIP) Session

There will be a WIP session where presenters provide brief (5-minute) talks on their on-going work, with fresh problems/solutions. WIP content is typically material that may not be mature or complete enough for a full paper submission and will not be included in the proceedings. Authors are invited to submit a one-page abstract or a 5-minutes pre-recorded presentation (voice over PowerPoint). Please use the IEEE conference paper template when preparing the one-page abstract. Feel free to condense the author list contents to offer more space.


Work in Progress (WIP) submissions due: Sep. 29, 2020, 11:59 PM AoE - note new date
Notification: On or before Oct. 1, 2020
Pre-recorded presentation due: Oct. 7, 2020, 11:59 PM AoE - note new date

Submissions by email: Please email your submission as a PDF attachment of the one-page abstract OR as a link to your pre-recorded presentation to and . Put "PDSW 2020 WIP" as the first part of the message subject. To verify your submission a reply will be made indicating official submission. If you do not receive such an email within 2 hours of the above deadline, please forward the original submission again.
