Expand description

Heuristic wgpu (Device::Gpu) cost model.

Implementations§

Source §

impl WgpuCostModel

Source

pub fn new() -> Self

Trait Implementations§

Source §

impl BackendCostModel for WgpuCostModel

Available on crate feature gpu only.

Source §

fn device(&self) -> Device

Identify which device this model is for.

Source §

fn sgemm_gflops(&self, _m: usize, _k: usize, _n: usize) -> f64

Effective f32 sgemm throughput in GFLOP/s for the most-used kernel path at the given dimensions. Backends should return their best sustained rate (not peak).

Source §

fn dispatch_overhead_ns(&self) -> f64

Cost to dispatch one kernel (function call, BLAS setup, etc.) in ns.

Source §

fn roundtrip_overhead_ns(&self) -> f64

Cost to commit + wait for a command buffer / forward pass in ns. Roughly amortized per-forward overhead independent of kernel count.

Source §

fn memory_bw(&self) -> f64

Memory bandwidth in bytes/ns (== GB/s).

Source §

fn num_threads(&self) -> usize

Number of compute threads available.

Source §

impl Default for WgpuCostModel

Available on crate feature gpu only.

Source §

fn default() -> Self

Returns the “default value” for a type. Read more

Source §

impl<T, U> Into for T
where U: From<T>,

Source §

fn into(self) -> U

Source §

impl<T> IntoEither for T

Source §

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more

Source §

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
