Struct KernelReductionConfig 

pub struct KernelReductionConfig {
    pub enabled: bool,
    pub op: ReductionOp,
    pub accumulator_type: String,
    pub use_cooperative: bool,
    pub shared_array_name: String,
    pub accumulator_name: String,
}

Configuration for global reductions in a ring kernel.

This enables algorithms like PageRank to perform global reductions (e.g., computing dangling node sum) within the kernel using a two-phase reduce-and-broadcast pattern.

Fields

enabled: bool

Whether global reduction is enabled.

op: ReductionOp

The reduction operation to perform.

accumulator_type: String

Type of the accumulator (e.g., “double”, “float”, “int”).

use_cooperative: bool

Use cooperative groups for grid-wide sync (requires CC 6.0+). If false, falls back to software barrier.

shared_array_name: String

Name of the shared memory array for block reduction.

accumulator_name: String

Name of the global accumulator variable.
