Struct MuonNsXtx 

pub struct MuonNsXtx {
    pub name: &'static str,
    pub id: String,
    pub transpose: bool,
    pub block_r: i32,
    pub block_k: i32,
    pub group_r: i32,
    pub kernel_source: String,
    pub entry_point_source: String,
    pub source: String,
}

Gram matrix: T = X·Xᵀ (!TRANSPOSE) or T = Xᵀ·X (TRANSPOSE).

Both cases are expressed as A @ Aᵀ with different views of X:

• !TRANSPOSE → A = X [M, N], output T [M, M], contraction K = N.
• TRANSPOSE → A = Xᵀ [N, M], output T [N, N], contraction K = M.

stride_xm is the row stride of X (typically = N for row-major [M, N]).

Grid: [ceil(R/BLOCK_R)² grouped by GROUP_R, 1, 1] where R = M or N.

Fields

name: &'static str

The kernel function’s name (e.g. "flash_attention2_forward").

id: String

Unique kernel identifier: fn_name + dtype(s) + const values joined by “__”.

transpose: bool

Compile-time kernel constant, from the annotated fn’s const generics.

block_r: i32

Compile-time kernel constant, from the annotated fn’s const generics.

block_k: i32

Compile-time kernel constant, from the annotated fn’s const generics.

group_r: i32

Compile-time kernel constant, from the annotated fn’s const generics.

kernel_source: String

The original kernel function source.

entry_point_source: String

The Rust source of the generated C-ABI entry-point wrapper function.

source: String

Combined source (kernel_source + "\n\n" + entry_point_source); used by the Kernel trait.

Implementations

impl MuonNsXtx

pub fn new(transpose: bool, block_r: i32, block_k: i32, group_r: i32) -> Self

Constructs a new kernel instance for these compile-time parameters.

Trait Implementations

impl Kernel for MuonNsXtx

type Args<'__a> = (*mut f32, *mut f32, i32, i32, i32)

This kernel’s launch-argument tuple type.

fn id(&self) -> String

A content hash of this kernel’s source, used as a cache key.

fn name(&self) -> &str

This kernel’s name.

fn source(&self) -> &str

This kernel’s full source (DSL + kernel body + entry point wrapper).

fn kernel_source(&self) -> &str

This kernel’s body source, without the entry-point wrapper.

fn entry_point_source(&self) -> &str

Returns the Rust source of the generated C-ABI entry-point wrapper function.

fn entry_point_name(&self) -> String

Returns the PTX symbol name for this kernel: "{name}_entry_point".
