Online Game Cluster

Posted by timothy on from the drool-pools dept.

axehind writes "Carlo Daffara posted to the openMosix mailing list about his game cluster. It's a 6 node cluster using Athlon XP cpus and running linux & openmosix (with some qdisc trickery) for the OS. It is used to host approximately 1000 users playing online games, like Jedi Knight and Quake III. Here's a link (italian) to the pictures."

    That same cluster spec running 1 instance of a game for someone to play on :). Someday I hope for clustering software to be to the point where when someone at a LAN party goes to sleep, their processing power can be used to help other machines.

  2. Why use Mosix ? by boaworm · · Score: 4, Interesting

    OpenMosix is used for load balancing, allowing processess to migrate during runtime.. I wonder what happens if you are trying to "gib/frag" someone and the server process migrates to another node .. ;-)

    It seems to me it would make more sense to use only the mentioned queue-system to position the games evenly.

  3. Why not make ONE game... by SexyKellyOsbourne · · Score: 4, Interesting

    That uses all CPU resources of a cluster, and leap 10 years into the future?

    The AI would use genetic algorithms, the sound would have every echo and diffusion effect possible, the graphics would use real-time raytracing, and the level count would be as extreme poly as possible. Simply spare nothing when it comes to CPU power, and just let it fly.

    Just use nothing but outright raw CPU power to render the whole thing.

      The same reason that game companies don't make games for machines with 8 CPUs or 4 CPUs, or even 2 CPUs. People just don't have machines out there to play the game.

      You can do it server-side, because some geek just has to put together a bunch of computers. On the client-side, can you imagine that 12 year old that keeps fraggin you when you're playing RtCW online putting together a cluster of computers? (That was rhetorical)

      "True to life" AI, does not imply good "Game" AI.

      The network latency would kill you. Motherboards are moving to AGP 8x so that they can get more bandwidth to the graphics card.
