Struct PersistentFdtdConfig 

pub struct PersistentFdtdConfig {
    pub name: String,
    pub tile_size: (usize, usize, usize),
    pub use_cooperative: bool,
    pub progress_interval: u64,
    pub track_energy: bool,
    pub idle_sleep_ns: u32,
    pub use_libcupp_atomics: bool,
}

Configuration for persistent FDTD kernel generation.

Fields

name: String

Kernel function name.

tile_size: (usize, usize, usize)

Tile size per dimension (cells per block).

use_cooperative: bool

Whether to use cooperative groups for grid sync.

progress_interval: u64

Progress report interval (steps).

track_energy: bool

Enable energy calculation.

idle_sleep_ns: u32

Nanosleep duration for idle spin-wait (nanoseconds). Used when the kernel has no work to do, reducing power consumption.

use_libcupp_atomics: bool

Use libcu++ ordered atomics (cuda::atomic_ref) for queue operations. Requires CUDA 11.0+ toolkit. When false (default), uses legacy __threadfence_system() pairs.

Implementations

impl PersistentFdtdConfig

pub fn new(name: &str) -> Self

Create a new config with the given name.

pub fn with_tile_size(self, tx: usize, ty: usize, tz: usize) -> Self

Set tile size.

pub fn with_cooperative(self, use_coop: bool) -> Self

Set cooperative groups usage.

pub fn with_progress_interval(self, interval: u64) -> Self

Set progress reporting interval.

pub fn with_idle_sleep(self, ns: u32) -> Self

Set idle sleep duration in nanoseconds. Controls power consumption during spin-wait when no work is available.

pub fn with_libcupp_atomics(self, enabled: bool) -> Self

Enable libcu++ ordered atomics for queue operations. Requires CUDA 11.0+ toolkit.

pub fn threads_per_block(&self) -> usize

Calculate threads per block.

pub fn shared_mem_size(&self) -> usize

Calculate shared memory size per block (tile + halo).

Trait Implementations

impl Clone for PersistentFdtdConfig

fn clone(&self) -> PersistentFdtdConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PersistentFdtdConfig

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