pub unsafe fn subgroup_clustered_s_min<const CLUSTER_SIZE: u32, I: VectorOrScalar<Scalar = impl SignedInteger>>(
value: I,
) -> I
Expand description
A signed integer minimum group operation of all value
operands contributed by active invocations in the group.
Result Type must be a scalar or vector of integer type.
Execution is a Scope that identifies the group of invocations affected by this command. It must be Subgroup.
The identity I for Operation is INT_MAX
. If Operation is ClusteredReduce
, ClusterSize
must be present.
The type of value
must be the same as Result Type.
ClusterSize
is the size of cluster to use. ClusterSize
must be a scalar of integer type, whose Signedness operand is 0. ClusterSize
must come from a constant instruction. Behavior is undefined unless ClusterSize
is at least 1 and a power of 2. If ClusterSize
is greater than the size of the group, executing this instruction results in undefined behavior.
Requires Capability GroupNonUniformArithmetic
and GroupNonUniformClustered
.
ยงSafety
ClusterSize
must not be greater than the size of the group
