Shard Request: Minimum CPU on all shards


  • Culture

    I want to restart this discussion now that CPU management between shards is a thing.



  • I think that it would be interesting to have the minimum amount of CPU on each shard be determined by GCL. Maybe using something like min_CPU = max(5, floor(10 / GCL)).

    For all the people who have been following this, you should know that this request has been rejected by the admins. Looks like we're going to be a "multiple worlds" system instead of a single unified world as the game was originally started.

    Multiple/single world aspect has nothing to with the CPU topic. It's all about physical connectivity (portals) rather than resources management implementation details. If you want to have 1,5,10,20 CPU on every shard in the game, just set it, you got the API. 12-hours timeout is not a game changer in any way.



  • How about not having a min cpu but instead have a baseline bucket that lets your code execute for a few ticks. That will let your code request more cpu when it sees that it needs to, allowing isolated code execution rather than each shard managing the other ones.

    Isn't this what the new shard cpu API has?

    Each shard has the 10,000 CPU bucket filled initially, so that if it runs it can request more CPU. This seems like more than enough, especially since you'll only need to be requesting more CPU from 0 CPU the first time you're running on the shard.

    I would assume the first single creep will always have a relatively low CPU load? Using 5 cpu per tick, even with 2 500-CPU global resets, you'd have 1800 ticks to request more CPU and set things up.

    Do you think you'll ever let us have more than 300 CPU per-account?

    Like, if the 300 CPU cap were made per-shard, and you continued to gain CPU from GCL after 27, that would be a cool compromise. Eventually we can have a few extra CPU levels that force us to become intershard to use them.

    @anisoptera I'm not sure forcing players to become inter-shard is a good idea.

    @artch I mean, you wouldn't be forced to in the sense that you have to or you're crippled. But there would be resources that you'll get "for free" by taking the effort, similarly to how you can ignore memory segments, but if your code takes advantage of them, you get 10MB more memory "for free".

    You don't get that additional CPU today at all; if you don't go intershard nothing changes. But if you are extremely high GCL, you'd get a little bonus if you do.

    @anisoptera Yes, I can see what that means. Still, it forces high-level players to some specific play style, and this might be a bad thing.
