On Tuesday, 12th of January 2016, the ATLAS@Home volunteer computing project reached a new milestone. The project's volunteers contributed more than 10,000 computing cores in parallel to simulate 13 TeV Monte-Carlo proton-proton collisions in the ATLAS detector, thus producing two-photon samples to study the Higgs boson properties. Volunteers based all over the world have been contributing their computing power to ATLAS since the beginning of 2014, with the number of ATLAS@Home participants increasing steadily ever since. Almost 7000 users with 9000 personal computers currently participate in ATLAS@Home. Many of them are active all the time and provide improvements to the project's stability and performance optimisations. ATLAS@Home is now one of the largest computing sites participating in ATLAS distributed computing, even larger than some of the Tier-1 centres.
