Module fdtd_dsl 

FDTD kernel defined using the Rust DSL.

This module demonstrates how to define stencil kernels in pure Rust that get transpiled to CUDA at compile time.

The generated CUDA code is equivalent to the handwritten version in shaders/fdtd_tile.cu, but is written in a high-level Rust DSL.

Structs

GridPos

CPU-side GridPos for when cuda-codegen is not enabled.

Functions

fdtd_tile_step_dsl

Run FDTD on an entire tile using the DSL kernel.

fdtd_wave_step_cpu

FDTD wave equation kernel for 16x16 tiles with 1-cell halo.

fdtd_wave_step_dsl

FDTD wave equation kernel using the GridPos DSL.
