ruda-kernel

Rust kernel DSL, reusable kernel building blocks, and runtime-generic device tensor operations. This is the kernel-authoring layer, not the high-level ruda-tensor::api::Tensor interface.

Interfaces

• dsl: kernel types, IR expansion, and launch interfaces.
• library: reusable device-kernel building blocks.
• tensor: device tensor allocation, transfer, readback, and operations.
• template: host source templates integrated with compiled kernel tasks.

Usage

Cargo package: ruda-kernel. Rust import: ruda_kernel.

[dependencies]
ruda-kernel = "0.1"

Typed pointers

The additive DSL interface is Ptr<E, S, A> and TypedSlice<E, S, A>, where S is GlobalSpace, Workgroup, or Local, and A is ReadOnly (the default) or ReadWrite. Convert an existing slice with .typed::<GlobalSpace>(), .typed::<Workgroup>(), or .typed::<Local>(); its storage origin is checked during kernel expansion. .ptr(index) produces an element pointer. Pointers support .offset(elements), .load(), .read_only(), and .select(condition, otherwise); .store(value) is available only for ReadWrite. Selected pointers must have the same element, address-space, and permission types. Typed slices support .len() and .slice(start, end).

These are logical storage views, not arbitrary native addresses. Address-space and permission labels remain in IR until backend lowering; writable global views also require a writable kernel binding. Existing slices and native pointer operations remain available. Typed load/store currently supports non-atomic elements; this interface does not establish GPU alias, lifetime, or race-freedom proofs.
