Call for Papers

Nowadays, concurrent and distributed systems play a role in a variety of computing applications. This is supported by the widespread use of computing architectures based on multi-core processors or distributed computing units, which have become a de facto standard at any system scale.
However, the increasing level of hardware parallelism and heterogeneity has made concurrent and distributed systems even more challenging to design, analyse and optimize. In particular, this concerns factors like performance and energy efficiency, which are known to be highly interrelated. Nevertheless, they play key roles, especially given the recent rise in energy demand from many IT applications. Examples include AI model training and inference, Big Data Analytics, high-performance computing and simulation, cryptography, high-resolution video encoding, and many more besides.

In concurrent and distributed systems, energy efficiency and performance are affected in complex ways by multiple factors, such as the concurrent use of computing resources, the distributed communication, the presence of (distributed) data dependencies and the need to synchronize the execution of concurrent threads/processes. However, these and other factors also offer opportunities to be explored in the design of techniques and tools for improving both energy efficiency and performance.

PECS aims to establish a venue for both academia and industry to discuss challenges and perspectives, and to explore methods, techniques and tools, for energy efficiency and performance analysis and optimization in concurrent and distributed systems.

PECS calls for high-quality research papers on all aspects of energy efficiency, performance and their interrelations in concurrent and/or distributed computing systems, focusing on (but not limited to) the following topics:

- Energy efficiency and performance analysis, modelling and evaluation in concurrent and distributed systems and architectures
- Energy-Aware programming and green software design methods for concurrent and distributed systems
- Energy efficiency and performance trade-offs in parallel and distributed AI model training and inference
- GreenOps for concurrent and distributed software systems and architectures
- Analysis and optimization of energy efficiency and performance in heterogeneous computing architectures
- Energy-efficient and performance optimized algorithms and frameworks for (Big) Data Processing
- Energy efficiency in high-performance computing platforms and applications
- Energy efficiency and performance aspects in Cloud, IoT, Edge, Fog computing, and Computing Continuum
- Approaches and techniques for improving energy efficiency and performance in data management and services
- Energy efficiency and performance evaluation and optimization in operating systems, networks and virtualized systems
- Energy impact evaluation and optimization in concurrent and distributed algorithms for cybersecurity

Paper Preparation Guidelines

PECS believes that energy plays a fundamental role in modern computer systems. Therefore, PECS does not accept papers that focus exclusively on performance while completely ignoring energy aspects. Papers are expected to include at least some measurements and/or relevant considerations related to energy usage of systems under consideration. Papers that do not meet these requirements may be rejected prior to the review process.

Papers should present novel contributions and should not have been submitted for publication elsewhere. Papers must be written in English, with a minimum of 10 and a maximum of 12 pages, including text, references, appendices, figures and any other elements. Papers with less than 10 pages are considered short and can be presented at the workshop, but they will not appear in the workshop proceedings. Papers must be formatted according to LNCS guidelines (https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines). Papers must be submitted via EasyChair (the submission link is available on the PECS 2026 website - https://pecs-workshop.github.io).

PECS employs a double-blind peer review process, i.e., the identities of authors and reviewers are not disclosed to each other. Therefore, all information that may allow authors to be identified must be removed from the submitted papers. In particular, this includes author names and affiliations, acknowledgments, funding information, and any references to authors' previous work that may reveal their identity. Furthermore, authors should ensure that PDF metadata does not contain identifying information. All the above details may be added later to accepted papers. Submissions that fail to adhere to these anonymity requirements may be rejected without review.

Authors are encouraged to ensure their papers clearly outline the following aspects:

- Motivation of the presented research study
- Limitations of existing studies, approaches, or solutions
- Novel contributions of the paper
- Methodology and tools employed in the study
- Availability of artifacts, datasets, or other tools to support reproducibility (where applicable)
- Validity and limitations of the proposed study

Reviewers will take these aspects into account during the evaluation process.

Any use of AI-generated content, including text, images, data, etc, must be disclosed in a specific section (for example, in a section at the end of the paper entitled "Information on AI-Generated Content"), except in cases where AI tools are used solely for improving presentation, such as for grammatical corrections or syntactic checks. Authors are solely responsible for the content of their papers.

***************

Paper Publication

Workshop proceedings will be published in a dedicated Springer LNCS volume. Only accepted papers presented at the workshop will be published in the workshop proceedings (excluding short papers). At least one author per paper is required to register for the workshop.

Venue

PECS 2026 is co-located with the 32nd International European Conference on Parallel and Distributed Computing (Euro-Par 2026) and will be held in Pisa, Italy.
