The Open Science Grid (OSG) is a distributed computing project founded in 2004. On August 5, 2022, research in Conway's Game of Life was approved as a project on the grid.[1]
Initially, the only program ran on the OSG was apgsearch. and the first hauls were submitted on August 9.[2] Unlike Charity Engine, the OSG also includes GPU resources and can therefore run apgsearch's GPU symmetries. Additionally, GPU searching is optimized to recognize long-lasting soups, high-period oscillators, and nonstandard spaceships, while usually ignoring still lifes and diehards.
Starting on August 11, 2022, OSG has contributed CPU resources to search randomly generated 5-glider collisions for the purpose of finding new glider syntheses.[3] The results can be found in the moog_stdin[note 1] symmetry. Starting on September 11, 2022, 6-glider collisions have been censused by the OSG as well.[4]
Starting January 2023, OSG has ran DiKpIx, Darren Li's modification of ikpx2.[5]
Notable discoveries include:
- September 2022: A predecessor for a 32-cell burloaferimeter variant,[6] leading to it being synthesized with only 9 gliders, the least known for any period-7 oscillator[7]
- September 2022: A partial synthesis of caterer, leading to it being synthesized with only 5 gliders.[8]
- October 2022: 76P86, the smallest known period-86 oscillator.[9]
- November 2022: The first seminatural fourfold occurrence of the Gosper glider gun mechanism and the first seminatural occurrence of the pufferfish's p36 crawler, a dimer form of a new period-16 oscillator mechanism
- December 2022: An unnamed period-10 oscillator that can be monomerised in many ways.[10]
- January 2023: Darren Li used Open Science Grid and a modified ikpx2 to find a surprisingly small (2,1)c/6 tagalong, which can be attached to Sir Robin, Sprayer, and various minstrels in a wide variety of ways, including a connection to itself.[11][12]
