What does it look like?

Here is a simple fragment shader with uniform buffers:

const std = @import("std");
const gpu = std.gpu;

const UBO = extern struct {
    object_color: @Vector(4, f32),
    light_color: @Vector(4, f32),

This is a WIP of a cheat-sheet that I will finish Eventually™

Types

Mapping of the shader types to Heaps types:

Float = Float
Int = Int
Bool = Bool

How to setup `nvidia-container-runtime` and podman/runc

Podman is such a cool project! However, there is no easy way to setup the nvidia-container-runtime and podman so that we can run unprivileged container in a gpu host. This is specially interesting in environments with multiple people accessing the same host (strong isolation between containers!!!).

Steps to setup the whole system

Install podman and friends (buildah and skopeo)

Ubuntu: add-apt-repository -y ppa:projectatomic/ppa && apt install podman buildah skopeo
