LHC@home is a volunteer distributed computing project operated by CERN using the BOINC platform. The project allows volunteers worldwide to donate unused computing resources to help physicists study particle physics, accelerator physics, and simulations related to the Large Hadron Collider (LHC).[1]

Wikipedia page

LHC@home

History

LHC@home was launched on 1 September 2004 as one of the earliest large-scale scientific volunteer computing projects associated with CERN.[2] The original application, SixTrack, was created to study the long-term stability of particle beams inside the Large Hadron Collider.

The project rapidly attracted thousands of volunteers shortly after launch. CERN used the distributed simulations to validate beam stability calculations and machine configurations for the LHC before its activation.[3]

Over time, additional applications were added to support detector simulations and theoretical physics workloads, many of which require virtualization technologies such as VirtualBox or Docker containers.

Goal

The primary goal of LHC@home is to assist CERN physicists with computationally intensive simulations related to particle accelerators and detector experiments.[4]

Project objectives include:

  • Helping design, optimize, and maintain the Large Hadron Collider
  • Simulating particle beam dynamics
  • Supporting detector experiment simulations
  • Comparing theoretical predictions with experimental data
  • Assisting research into dark matter, antimatter, and fundamental particles

Applications

SixTrack

SixTrack is the original LHC@home application and performs accelerator physics simulations to analyze the stability of proton beams circulating in the LHC.[5]

The software was developed by physicists in CERN's Accelerators and Beams Department. Results generated by volunteers have been used to improve understanding of beam dynamics and long-term particle stability inside accelerator rings.

ATLAS

The ATLAS@home application allows volunteers to run simulations for the ATLAS experiment, one of the largest particle detector experiments at CERN.[6]

ATLAS tasks often use virtualization through VirtualBox or native Linux execution environments.

CMS

CMS@home supports simulations for the Compact Muon Solenoid experiment.[7]

The application processes Monte Carlo simulation workloads and event reconstruction tasks related to proton collision data.

LHCb / Beauty

The LHCb (Beauty) application studied the decay properties of beauty quarks and antimatter asymmetry.[8]

The CERN logo – international organization which operates the world's largest particle physics laboratory

Volunteer participation for LHCb workloads was paused indefinitely in November 2018.[9]

Test4Theory

Test4Theory was introduced in 2011 and uses virtualization technologies to run simulations of high-energy particle collisions.[10]

The application uses CERNVM and later Docker-based infrastructure to provide portable scientific environments across volunteer computers.

Xtrack

In 2025 CERN introduced the experimental Xtrack application for beta testing on the LHC@home platform.[11]

Xtrack is intended as a next-generation beam dynamics simulation framework.

Technology

LHC@home uses the BOINC middleware platform developed at the University of California, Berkeley.[12]

Several applications require:

  • Hardware virtualization support
  • VirtualBox
  • Docker containers
  • CERNVM virtual machine images

Many workloads distribute large datasets and may require several gigabytes of storage and memory.

The Large Hadron Collider at CERN

Scientific impact

The project has contributed to accelerator optimization and detector simulations associated with the Large Hadron Collider.[13]

Volunteer computing resources supplement CERN's Worldwide LHC Computing Grid infrastructure by providing additional computational power for simulation workloads.

Community

LHC@home maintains active message boards and volunteer discussion forums where users discuss optimization, virtualization setup, workunit availability, and troubleshooting.[14]

Community discussions on Reddit and BOINC forums frequently cover VirtualBox compatibility, Docker support, Linux configuration, and long-running Theory tasks.[15]

Project statistics

The ATLAS detector

As of 2024–2026, LHC@home reported approximately:[16]

  • Over 178,000 registered users
  • More than 577,000 participating hosts
  • Around 52 TFLOPS of computing performance
  • Thousands of active volunteer systems worldwide

Scientific publications

The CMS detector
