Enum Exec 

pub enum Exec {
    Native(MmaKind),
    ExactFp8Emulation,
    NoPath(MmaKind),
    NoFp4Kernel {
        fp8: bool,
    },
}

2026-09-30: The execution of one node’s declared formats.

Variants

Native(MmaKind)

2026-09-30: The device’s MMA of this kind runs it (weights narrower than the activation widen in registers: W4A16, W8A16).

ExactFp8Emulation

2026-09-30: NVFP4 operands converted exactly to E4M3 and run on the FP8 MMA.

NoPath(MmaKind)

2026-09-30: No MMA of the device can run the activation format.

NoFp4Kernel

2026-10-01: The device has the FP4 block-scale MMA but its class compiles no FP4 kernel for the node: the exact E2M1 -> E4M3 path on the FP8 MMA where the device has one (fp8), else no path.

Fields

fp8: bool

2026-10-01: The device has the FP8 MMA.

Implementations

impl Exec

pub fn describe(self) -> String

2026-09-30: The report spelling.

pub fn peak(self, r: &Roofline) -> (f64, &'static str)

2026-10-01: The tensor peak of r this execution runs at, and its name.

Trait Implementations

impl Clone for Exec

fn clone(&self) -> Exec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Exec

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

Formats the value using the given formatter.

impl Hash for Exec

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Exec

fn cmp(&self, other: &Exec) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Exec

fn eq(&self, other: &Exec) -> 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.

impl PartialOrd for Exec

fn partial_cmp(&self, other: &Exec) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
