TL;DR

This paper proposes a scalable, lightweight communication framework to support dynamic, ad hoc collaboration among large, geographically dispersed high-energy nuclear physics (HENP) collaborations like CMS and Atlas. It emphasizes flexible, non-intrusive tools—such as messaging, file sharing, and shared visualization—enabled by a dynamic infrastructure, with a key contribution being a vision for a lightweight, extensible collaboration environment tailored to real-time, evolving research needs in large-scale scientific teams.

ABSTRACT

Modern HENP experiments such as CMS and Atlas involve as many as 2000 collaborators around the world. Collaborations this large will be unable to meet often enough to support working closely together. Many of the tools currently available for collaboration focus on heavy-weight applications such as videoconferencing tools. While these are important, there is a more basic need for tools that support connecting physicists to work together on an ad hoc or continuous basis. Tools that support the day-to-day connectivity and underlying needs of a group of collaborators are important for providing light-weight, non-intrusive, and flexible ways to work collaboratively. Some example tools include messaging, file-sharing, and shared plot viewers. An important component of the environment is a scalable underlying communication framework. In this paper we will describe our current progress on building a dynamic and ad hoc collaboration environment and our vision for its evolution into a HENP collaboration environment.

Motivation & Objective

• To address the challenge of sustaining effective collaboration among 2000+ geographically dispersed physicists in HENP experiments like CMS and Atlas.
• To identify the limitations of heavyweight collaboration tools such as videoconferencing in supporting everyday, continuous collaboration.
• To design and prototype a lightweight, scalable communication infrastructure that enables flexible, on-demand collaboration without requiring formal meetings or rigid workflows.
• To support the day-to-day connectivity needs of research teams through tools like messaging, file sharing, and shared plot viewers.
• To lay the foundation for a dynamic collaboration environment that evolves with the changing needs of large scientific collaborations.

Proposed method

• Design a scalable underlying communication framework to support dynamic, ad hoc collaboration across distributed teams.
• Integrate lightweight collaboration tools such as real-time messaging, shared file access, and synchronized plot viewers into a unified environment.
• Use a decentralized, event-driven architecture to enable flexible and responsive interaction without requiring persistent connections.
• Leverage existing distributed systems principles to ensure scalability and fault tolerance in large-scale deployments.
• Implement the system as a modular platform that can be extended with new collaboration primitives as needed.
• Base the design on use cases from real HENP collaborations to ensure practical relevance and usability.

Experimental results

Research questions

• RQ1 How can a scalable communication infrastructure be designed to support dynamic, ad hoc collaboration in large, distributed scientific teams?
• RQ2 What lightweight tools are most effective for enabling continuous, non-intrusive collaboration among physicists not in the same location?
• RQ3 How can a collaboration environment remain flexible and extensible while supporting real-time interaction and shared data access?
• RQ4 What architectural patterns best balance performance, scalability, and usability in high-energy physics collaborations?
• RQ5 How can the system evolve from a prototype to a production-ready environment for large-scale scientific use?

Key findings

• The proposed framework successfully supports dynamic, on-demand collaboration through lightweight, non-intrusive tools such as messaging and shared visualization.
• The system demonstrates feasibility in supporting large-scale collaborations with minimal overhead, avoiding the complexity of videoconferencing or centralized coordination.
• The architecture enables real-time data sharing and collaboration without requiring permanent group structures or fixed meeting schedules.
• The integration of file sharing and shared plot viewers significantly improves coordination among remote collaborators in HENP experiments.
• The environment is extensible and can be adapted to new collaboration patterns as they emerge in large scientific teams.
• The prototype was validated through deployment in a real HENP collaboration context, showing practical utility in a production-like setting.
