Struct TileKernelGrid 

pub struct TileKernelGrid {
    pub width: u32,
    pub height: u32,
    pub params: AcousticParams,
    /* private fields */
}

A simulation grid using tile actors with K2K messaging.

Fields

width: u32

Grid dimensions in cells.

height: u32

params: AcousticParams

Acoustic simulation parameters.

Implementations

impl TileKernelGrid

pub async fn new( width: u32, height: u32, params: AcousticParams, backend: Backend, ) -> Result<Self>

Create a new tile-based kernel grid.

pub async fn with_tile_size( width: u32, height: u32, params: AcousticParams, backend: Backend, tile_size: u32, ) -> Result<Self>

Create a new tile-based kernel grid with custom tile size.

pub async fn step(&mut self) -> Result<()>

Perform one simulation step using tile actors with K2K messaging.

pub fn enable_cuda_persistent(&mut self) -> Result<()>

Enable GPU-persistent CUDA compute.

This mode keeps pressure state GPU-resident and only transfers halos for K2K communication. Much faster than upload/download per step.

pub fn is_gpu_persistent_enabled(&self) -> bool

Check if GPU-persistent mode is enabled.

pub fn gpu_persistent_backend(&self) -> Option<GpuPersistentBackend>

Get which GPU-persistent backend is active.

pub fn step_cuda_persistent(&mut self) -> Result<()>

Perform one simulation step using GPU-persistent CUDA compute.

State stays GPU-resident. Only halos are transferred for K2K messaging.

pub fn read_pressure_from_cuda(&self) -> Result<Vec<Vec<f32>>>

Read pressure grid from CUDA for visualization.

pub fn inject_impulse_cuda( &mut self, x: u32, y: u32, amplitude: f32, ) -> Result<()>

Upload a pressure impulse to CUDA GPU-persistent state.

pub fn inject_impulse(&mut self, x: u32, y: u32, amplitude: f32)

Inject an impulse at the given global grid position.

pub fn get_pressure_grid(&self) -> Vec<Vec<f32>>

Get the pressure grid for visualization.

pub fn max_pressure(&self) -> f32

Get the maximum absolute pressure in the grid.

pub fn total_energy(&self) -> f32

Get total energy in the system.

pub fn reset(&mut self)

Reset all tiles to initial state.

pub fn cell_count(&self) -> usize

Get the number of cells.

pub fn tile_count(&self) -> usize

Get the number of tile actors.

pub fn backend(&self) -> Backend

Get the current backend.

pub fn k2k_stats(&self) -> K2KStats

Get K2K messaging statistics.

pub fn set_speed_of_sound(&mut self, speed: f32)

Update acoustic parameters.

pub fn set_cell_size(&mut self, size: f32)

Update cell size.

pub async fn resize(&mut self, new_width: u32, new_height: u32) -> Result<()>

Resize the grid.

pub async fn shutdown(self) -> Result<()>

Shutdown the grid.

Trait Implementations

impl Debug for TileKernelGrid

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
