Aligned with Euro-Par 2026, the premier European conference addressing all facets of parallel and distributed processing, GraphSys ‘26 is the Fourth Workshop on Serverless, Extreme-Scale, and Sustainable Graph Processing Systems. GraphSys is a cross-disciplinary meeting venue focusing on state-of-the-art and emerging (future) graph processing systems, with an emphasis on causality and temporal graphs.

The workshop is designed for researchers, practitioners, and students interested in sustainable graph processing. Participants from academia, industry, government research labs, and nonprofit organizations are encouraged to attend and contribute to the GraphSys discussions and collaborations.

Paper submission

Submissions will be managed via EasyChair.

We invite:

  • Full papers (10–12 pages, LNCS format) — original work for publication in the workshop proceedings.
  • Short papers (6 pages) — work-in-progress, experience, and position papers; eligible for presentation; papers of less than 10 pages will be considered short papers (presentation at the workshop; inclusion in proceedings subject to Euro-Par/Springer policy).
  • Extended abstracts (2 pages) — addressing the workshop challenges (causal discovery in HPC and datacenter management; causal understanding of quantum uncertainty; causal hardware–software co-design).
  • Datasets — FAIR datasets that provide the rationale for system phenomena (e.g., intervention-based logs for root-cause analysis in HPC and quantum hardware).

All submissions must be in PDF format. Papers must be formatted according to the LNCS guidelines. Submission instructions and the EasyChair link will be published when the call opens (by March 13, 2026).

Topics of interest for GraphSys ‘26 include:

  1. System architectures and system designs for graph creation, enrichment, graph query, and graph analytics.
  2. Programming and data-level interfaces, APIs, and models for graph processing.
  3. Benchmarks, performance monitoring, measurement techniques, methods, metrics, tools, and instruments for graph processing.
  4. Sustainability metrics, tools, and instruments for real-world, analytical, and simulation-based approaches to performance analysis for graph processing systems.
  5. Parallel and distributed (including heterogeneous) algorithms and methods for graph processing.
  6. Serverless techniques, addressing graph processing challenges of full-automation software and data services with fine granularity and utilization-based billing.
  7. Empirical case studies of graph processing environments, applications, and systems, including comparative performance studies and benchmarking of real-world and production graph-processing systems.
  8. Methodological aspects of software engineering, performance engineering, and computer systems related to graph processing.
  9. Development and dissemination of FAIR datasets that provide the rationale for system phenomena, including intervention-based logs for root-cause analysis in HPC and quantum hardware.
