Struct DeviceResidentArrowShape 

pub struct DeviceResidentArrowShape {
    pub n: usize,
    pub p: usize,
    pub basis_cols: usize,
    pub d: usize,
}

SAE shape used by the resident inner-iteration workspace.

p is the target width and current shared-border width for this slice. The true SAE decoder has richer (basis × output) structure; slice 1 deliberately keeps that structure host-assembled into row_cross_slabs while preserving the qwen-scale target width in the Schur border.

Fields

n: usize

p: usize

basis_cols: usize

d: usize

Implementations

impl DeviceResidentArrowShape

pub const fn qwen_non_gating() -> Self

pub const fn color_arm() -> Self

Color-arm shape from the #1017 measured gap (n=180, p=5120, M≈9, K=1): few rows, very wide border. The dense-Schur device path (cuSOLVER border POTRF) handles the p=5120 border that exceeds the fused-kernel P_MAX.

Trait Implementations

impl Clone for DeviceResidentArrowShape

fn clone(&self) -> DeviceResidentArrowShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DeviceResidentArrowShape

impl Debug for DeviceResidentArrowShape

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

Formats the value using the given formatter.

impl Eq for DeviceResidentArrowShape

impl PartialEq for DeviceResidentArrowShape

fn eq(&self, other: &DeviceResidentArrowShape) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
