Enum GroupOperation

Source
#[non_exhaustive]
pub enum GroupOperation { Reduce = 0, InclusiveScan = 1, ExclusiveScan = 2, ClusteredReduce = 3, PartitionedReduceNV = 6, PartitionedInclusiveScanNV = 7, PartitionedExclusiveScanNV = 8, }
Expand description

Defines the class of group operation.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Reduce = 0

A reduction operation for all values of a specific value X specified by invocations within a workgroup.

§

InclusiveScan = 1

A binary operation with an identity I and n (where n is the size of the workgroup) elements[a0, a1, … an-1] resulting in [a0, (a0 op a1), …(a0 op a1 op … op an-1)]

§

ExclusiveScan = 2

A binary operation with an identity I and n (where n is the size of the workgroup) elements[a0, a1, … an-1] resulting in [I, a0, (a0 op a1), … (a0 op a1 op … op an-2)].

§

ClusteredReduce = 3

The GroupOperation ClusteredReduce.

All instructions with a GroupOperation require an additional ClusterSize parameter when GroupOperation is ClusteredReduce. To map this requirement into rust, all function have a base version accepting GroupOperation as a const generic, and a _clustered variant that is fixed to ClusteredReduce and takes the additional ClusterSize parameter as a const generic. To not accidentally use a ClusteredReduce in the base variant of the function, it was removed from the GroupOperation enum and instead resides individually.

§

PartitionedReduceNV = 6

Reserved.

Requires Capability GroupNonUniformPartitionedNV.

§

PartitionedInclusiveScanNV = 7

Reserved.

Requires Capability GroupNonUniformPartitionedNV.

§

PartitionedExclusiveScanNV = 8

Reserved.

Requires Capability GroupNonUniformPartitionedNV.
