EPEW 2025: European Performance Engineering Workshop Catania, Italy, June 26, 2025 Conference website https://epew-workshop.github.io/ Submission link https://easychair.org/conferences/?conf=epew2025 CALL FOR PAPERS 21st European Performance Engineering Workshop (EPEW 2025) Catania, Italy - June 26, 2025 The European Performance Engineering Workshop (EPEW) is an annual event that aims to gather researchers from both the academia and industrial world working on all aspects of performance modeling and analysis. EPEW 2025 is co-located with the 39th ECMS International Conference on Modelling and Simulation (https://scs-europe.net/conf/ecms2025). SCOPE AND TOPICS The concept of performance in EPEW 2025 is considered in its broadest sense including the notions of Quality of Service, scalability as well as reliability, availability, and systems management, among others. Therefore, of particular interest are the ideas introducing new methods for evaluating complex systems, as well as innovative applications of methodologies and known techniques to the latest generation of systems, networks, and computer-based services. EPEW 2025 seeks papers based on the performance evaluation of systems from a theoretical and practical viewpoint. Application of performance evaluation techniques to emerging technologies, like cyber-physical systems ranging from mobile devices and Internet-of-Things (IoT), fog and edge computing, applications to large-scale cloud computing systems, smart grids, security infrastructures, are among the topics of interest to EPEW 2025. Topics of interest include but are not limited to the following topic areas: Theoretical advances in performance modeling and evaluation, such as: Probabilistic, stochastic, or performability models, such as Queueing Networks, Petri Nets, and Process Calculi; Specification of quantitative properties, Analytical and numerical solution techniques and simulation techniques, Quantitative model checking, equivalence checking, and static analysis Context-aware modeling and analysis techniques Machine learning and deep learning-based approaches for performance evaluation and analysis Multiformalism and Multiparadigm modeling approaches System, software, and network performance engineering, such as: Performance-oriented design, architecture, implementation, deployment, monitoring, and maintenance Constraint-based and model-driven system design Performance analysis, simulation, and experimental design Benchmark design and benchmark-based evaluation and monitoring Automated interpretation of analysis results Quality of service, and trade-offs between security, performance, dependability, energy consumption, usability, etc. Software performance modeling languages, model composition, and tool interoperability 6G and beyond Case studies, such as: Cloud systems, Hybrid Cloud, and Fog Computing Internet of Things Cyber-physical systems E-health systems Blockchain and Cryptocurrency applications Sharing services such as carshare and rideshare Electric vehicles and battery modeling Large-scale systems and scalability analysis of systems, robustness analysis of systems, resilience analysis of systems Industrial case studies, experience reports, and tools, with a solid analysis and theoretical background SUBMISSIONS EPEW 2025 features post-proceedings, with a two-phase review process: Authors are solicited to submit short papers of at most 7-10 pages for presentation at the workshop. Accepted short papers will not be published in the proceedings. Authors of accepted short papers will be invited to submit full papers of at most 15 pages (i.e., an extended version of the short paper) for publication in the Lecture Notes in Computer Science (LNCS) Series by Springer. All page limits include tables, figures, and references. All papers must be submitted electronically in Springer’s LNCS format (in PDF format) using EasyChair: https://easychair.org/my/conference?conf=epew2025 Springer encourages authors to include their ORCIDs in their papers. Authors should consult Springer's authors' guidelines and use Springer's LaTeX templates for the preparation of their papers. Submitted papers not complying with the above guidelines may be rejected without undergoing review. All submitted papers will be reviewed by the program committee based on technical quality, relevance, significance, and clarity. IMPORTANT DATES Short paper submission: April 1st, 2025 Acceptance notification for short papers: May 15th, 2025 Full paper submission (post-proceedings): July 31st, 2025 Acceptance notification for full papers: September 30th, 2025 All deadlines are UTC-12 (Anywhere on Earth). BEST PRESENTATION AWARD The EPEW 2025 organizing committee will select the best paper presentation, for which a certificate will be presented at the end of the workshop. Note that the selection is based on content, as well as presentation.
