Struct ReductionFusionGroup 

pub struct ReductionFusionGroup {
    pub id: usize,
    pub root: NodeId,
    pub sink: NodeId,
    pub members: Vec<NodeId>,
    pub pattern: ReductionPattern,
    pub config: KernelConfig,
    pub tag: String,
}

A reduction-broadcast region that the pass merges into a single kernel.

Members are listed in topological order (the rooting reduction first, the post-dominating sink last).

Fields

id: usize

Group identifier (sequential, 0-based).

root: NodeId

The rooting reduction node (single entry of the region).

sink: NodeId

The post-dominating exit node (single exit of the region).

members: Vec<NodeId>

All region members in topological order (root first, sink last).

pattern: ReductionPattern

Classified pattern shape.

config: KernelConfig

Combined launch configuration (uses the root’s config).

tag: String

Human-readable tag for debugging.

Implementations

impl ReductionFusionGroup

pub fn size(&self) -> usize

Returns the number of nodes merged by this region.

pub fn launches_saved(&self) -> usize

Returns the number of kernel launches this region eliminates (size - 1, since the whole region collapses to one launch).

Trait Implementations

impl Clone for ReductionFusionGroup

fn clone(&self) -> ReductionFusionGroup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReductionFusionGroup

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

Formats the value using the given formatter.

impl Eq for ReductionFusionGroup

impl PartialEq for ReductionFusionGroup

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