Enum SmAllocation

pub enum SmAllocation {
    Exact,
    Full,
    Ratio {
        max_extra_numerator: u32,
        max_extra_denominator: u32,
    },
}

Controls how Streaming Multiprocessors (SMs) are assigned cubes.

• Exact: Balanced allocation using GCD (e.g., 120 cubes, 16 SMs → 4 SMs × 30 cubes)
• Full: Uses all SMs even if it overallocates (e.g., 120 cubes, 16 SMs → 16 SMs × 8 cubes = 128 total cubes)
• Overallocate: Allows extra SMs within a specified fraction (e.g., up to 25% overuse)

Variants

Exact

Balanced: uses GCD to never exceed total cubes.

Full

Uses all SMs, possibly overallocating total cubes.

Ratio

Allows overallocating SMs up to a ratio.

Fields

max_extra_numerator: u32

max_extra_denominator: u32

Implementations

impl SmAllocation

pub fn allocate(&self, num_sms: u32, total_cubes: u32) -> (u32, u32)

Returns a pair (num_sms_used, cubes_per_sm) depending on the strategy

Trait Implementations

impl Clone for SmAllocation

fn clone(&self) -> SmAllocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SmAllocation

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

Formats the value using the given formatter.

impl Hash for SmAllocation

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 SmAllocation

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