In my configuration file, assuming we use my tester you basically configure the machine like this: player = Zen-4k desc = Zen at 4 playouts per move invoke = ssh foobar.com /home/joe/bin/zen -playouts 4000 level = 4000 Hash = 128 Of course this might look a lot different for Go, and I have no idea how zen is configured for level, etc. At the top of the configuration file you specify cpus because the tester is designed for multi-core and you might want to limit the number of simulatanteous games to 4 on a quad core, etc. But for this application that is not so relevant, so we would want to provide for a way to limit the number of running instances of ANY program on the host machine. For instance we might not want to be running more than 4 programs at any given time on the foobar.com machine. I think it might be easier to manually set these matches up with twogmp or something like that too. That would be easy.
