Module device 

Device abstraction following Tinygrad’s architecture.

This module provides a unified Device abstraction that owns:

• Renderer: Transforms UOp graphs into source code (ProgramSpec)
• Compiler: Transforms source code into executable bytes
• Runtime: Creates executable Programs from compiled bytes
• Allocator: Manages memory allocation for buffers

This design allows multiple backends (LLVM, CUDA, Metal, WebGPU) to coexist and share compiled kernels via the method cache.

Structs

CompiledSpec

Compilation result carrying source (JIT) or bytes (AOT).

Device

A device that owns renderer, compiler, runtime, and allocator.

ProgramSpec

Program specification containing source code and metadata.

Variable

A variable in the kernel (for symbolic shapes/strides).

Traits

Compiler

A compiler that transforms source code into a compiled specification.

Program

A compiled, executable kernel program.

Renderer

A renderer that transforms UOp graphs into source code.

Type Aliases

CompilerPair

A (Renderer, Compiler) pair for a specific backend.

RuntimeFactory

A factory function that creates executable Programs from a compiled specification.
