Enum CollectiveKernel 

pub enum CollectiveKernel {
    AllReduceMean,
}

Kernels used by crate::multi_gpu for collective (cross-device) operations. Kept as a sibling to OptimizerKernel rather than folded into it: a reduction is not an optimizer step, and giving it its own type keeps that honest at the API level.

Variants

AllReduceMean

Divide a local buffer by the replica count — the finishing step of a sum-then-average all-reduce. See wgsl::ALL_REDUCE_MEAN.

Implementations

impl CollectiveKernel

pub fn id(self) -> &'static str

Stable identifier, used to key the compiled-pipeline cache.

pub fn source_for(self, backend: GpuBackend) -> Option<&'static str>

Shader source for backend, or None when that backend has no source.

pub fn cache_key(self, backend: GpuBackend) -> &'static str

Cache key combining the kernel and the backend it was compiled for.
