What is the main difference compared to a centralized project like Seti@home?
There are two: Seti@home can scale at least up to 3’000’000 computers and GPU to 300’000 like Gnutella, although 2000 computers only are visible for each user. However, current GPU versions (0.9xx) scale only up to 60 nodes, we need to put more work into the communication layer. On ChessBrain, another centralized project, volunteers compute one chess match only. With GPU, where everyone can get and has to provide CPU-time, everyone could play chess against the virtual supercomputer, if parallelism would already work in the chess plugin. We present some centralized frameworks here.
