We are excited to announce the release of Ark.jl v0.1.0, an archetype-based entity component system (ECS) for Julia, ported from the Go ECS library Ark . If you are unfamiliar with ECS, scroll down to learn why it is especially relevant for the Julia community. Ark’s features Designed for performa…

Hi, I am following this discussion with eager as I have a possibly naive question. I was recently profiling Julog.jl, because it is an essential part of planning ecosystem in Julia. The julog is notoriously type unstable. But looking at definition of structures used within the engine Julog.jl/src/s…

Components and systems can be on the GPU, there is no restriction. Are you thinking about the underlying storage and therefore query logic to be on the GPU as well? There seems to be very little work on putting the entire ECS execution on the GPU.

Yes, the idea would be to run per-entity system loops (parallelized) on GPU, and also a non-per entity (n-body-interaction) system.

I don’t know Julog.jl at all, so it is hard to say anything in this regard.

Ark.jl v0.2.0 will come with configurable storage backends per component type, currently Vector and StructArray-(like). It can already be tested on the main branch. So it is probably possible to move the entire ECS data, or data for some components, to the GPU.

@simsurace Just wanted to let you know that entity relationships are now fully functional and available on the main branch. It will take some more time until we will release it officially, but if you want to give it a try, we would love to hear your feedback!

Awesome, can’t test right now but sometime in the coming weeks I’ll try some of our logistics stuff to use relations (delivery items in vehicles, vehicles in depots, etc.) and see how it goes.

@oschulz I would like to let you know that I’m trying to add GPU support to Ark.jl in this PR: Implement GPUVector by Tortar · Pull Request #470 · ark-ecs/Ark.jl · GitHub . If anyone spots any possible improvement for an agnostic hybrid container which runs most of the things on CPUs but can also off…
