Struct ReductionFusionPlan 

pub struct ReductionFusionPlan {
    pub groups: Vec<ReductionFusionGroup>,
    pub node_to_group: HashMap<NodeId, usize>,
}

The complete reduction-fusion plan produced by analyse.

Fields

groups: Vec<ReductionFusionGroup>

All matched reduction-fusion regions.

node_to_group: HashMap<NodeId, usize>

Map from a region member NodeId to its group index.

Implementations

impl ReductionFusionPlan

pub fn fusion_count(&self) -> usize

Returns the number of matched reduction regions.

pub fn nodes_saved(&self) -> usize

Returns the total number of kernel launches eliminated across all regions.

pub fn group_of(&self, node: NodeId) -> Option<&ReductionFusionGroup>

Returns the region that owns node, if any.

pub fn is_absorbed(&self, node: NodeId) -> bool

Returns true if node was absorbed into a fused region but is not that region’s root (i.e. it disappears as an independent launch).

Trait Implementations

impl Clone for ReductionFusionPlan

fn clone(&self) -> ReductionFusionPlan
