Query: Building a Distributed Computing System for LDMX: Challenges of creating
  and operating a lightweight e-infrastructure for small-to-medium size
  accelerator experiments   Particle physics experiments rely extensively on computing and data services,
making e-infrastructure an integral part of the research collaboration.
Constructing and operating distributed computing can however be challenging for
a smaller-scale collaboration. The Light Dark Matter eXperiment (LDMX) is a
planned small-scale accelerator-based experiment to search for dark matter in
the sub-GeV mass region. Finalizing the design of the detector relies on
Monte-Carlo simulation of expected physics processes. A distributed computing
pilot project was proposed to better utilize available resources at the
collaborating institutes, and to improve scalability and reproducibility. This
paper outlines the chosen lightweight distributed solution, presenting
requirements, the component integration steps, and the experiences using a
pilot system for tests with large-scale simulations. The system leverages
existing technologies wherever possible, minimizing the need for software
development, and deploys only non-intrusive components at the participating
sites. The pilot proved that integrating existing components can dramatically
reduce the effort needed to build and operate a distributed e-infrastructure,
making it attainable even for smaller research collaborations.
