The Virtual LHC@home project (formerly known as Test4Theory) allows users to participate in running simulations of high-energy particle physics using their home computers.
Lots of volunteers around the world are connected to this project running vLHCathome simulations right now. See where they are (map coordinates are randomized at city level for privacy; undetermined locations are shown in the Bermuda triangle). Or check the current list of top contributors at the vLHCathome Leaderboard.
Hopefully, these explanations can help give an idea of why the computing resources made available by volunteers in this way can be crucial for improving our understanding of what is really happening inside the beam pipe of the Large Hadron Collider. Soon, other types of simulations from the LHC experiments will be added to this project.
Therefore, if you like the project and want to collaborate:
- More about high energy physics simulations
- More about how volunteer input can help
- More about which programs and simulation packages we run
- More about project test phases, timelines, and future additions
- More about the teams behind LHC@home and vLHCathome and the software we use
- Scientific Review on Event Generators for LHC Physics (advanced)
"LHC@home 2.0 aims to bring the world’s largest particle accelerator into your home. The platform – an extension of the already successful LHC@home – allows volunteers to connect to CERN-based research projects simply by donating their extra computing power. The project vLHCathome, for example, simulates high-energy particle collisions which scientists can compare to real-life collisions, such as those occurring in the Large Hadron Collider (LHC)."
“My dream is to be able to establish a ‘virtual LHC’, which would require being able to generate 40 million events per second, as much as the real LHC, running at full steam,“ says Peter Skands, Science Project Leader for vLHCathome. “We estimate that it would take somewhere between 10 000 and 100 000 connected computers to achieve this, a combined amount of computing power that we have only faintly begun to imagine, since we started working with LHC@home 2.0. With the enthusiasm we have seen in the public so far, there definitely appears to be awesome possibilities for what we can do with this platform."
