Enum SmArch 

pub enum SmArch {
    Sm80,
    Sm89,
    Sm90a,
    Sm100,
}

CUDA streaming-multiprocessor architecture target. The dispatch table refuses to resolve any key whose arch is not in this list.

Variants

Sm80

Ampere (A100, A30) — fa2 only.

Sm89

Ada (RTX 40xx, L4) — fa2 only, supports fp8 cuBLASLt but not fa3.

Sm90a

Hopper (H100, H200) — fa3, fp8, TMA, WGMMA, persistent kernels.

Sm100

Blackwell (B100, B200) — forward-compat target; fa3 with fifth-gen tensor cores. Falls back to Hopper kernels for now.

Implementations

impl SmArch

pub fn nvrtc_flag(self) -> &'static str

CUDA --gpu-architecture string.

pub fn supports_fa3(self) -> bool

True if this arch supports FlashAttention v3 (Hopper+).

pub fn supports_fp8(self) -> bool

True if this arch supports fp8 e4m3 / e5m2 in FA3.

Trait Implementations

impl Clone for SmArch

fn clone(&self) -> SmArch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SmArch

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

Formats the value using the given formatter.

impl Hash for SmArch

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 PartialEq for SmArch

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