Struct ArgMax

pub struct ArgMax;

Compute the coordinate of the maximum item returning the smallest coordinate in case of equality.

Implementations

impl ArgMax

pub fn choose_argmax<N: Numeric>( items0: Line<N>, coordinates0: Line<u32>, items1: Line<N>, coordinates1: Line<u32>, ) -> (Line<N>, Line<u32>)

Compare two pairs of items and coordinates and return a new pair where each element in the lines is the maximal item with its coordinate. In case of equality, the lowest coordinate is selected.

pub fn __expand_choose_argmax<N: Numeric>( context: &mut CubeContext, items0: <Line<N> as CubeType>::ExpandType, coordinates0: <Line<u32> as CubeType>::ExpandType, items1: <Line<N> as CubeType>::ExpandType, coordinates1: <Line<u32> as CubeType>::ExpandType, ) -> <(Line<N>, Line<u32>) as CubeType>::ExpandType

Trait Implementations

impl Debug for ArgMax

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

Formats the value using the given formatter.

impl Reduce for ArgMax

type Instruction<In: Numeric> = ArgMax

impl<In: Numeric> ReduceInstruction<In> for ArgMax

type AccumulatorItem = (Line<In>, Line<u32>)

The intermediate state into which we accumulate new input elements. This is most likely a Line<T> or a struct or tuple of lines.

type SharedAccumulator = ArgAccumulator<In>

When multiple agents are collaborating to reduce a single slice, we need a share accumulator to store multiple AccumulatorItem. This is most likely a SharedMemory<Line<T>> or a struct or tuple of lined shared memories.

fn null_input(line_size: u32) -> Line<In>

A input such that Self::reduce(accumulator, Self::null_input(), coordinate, use_planes) is guaranteed to return accumulator unchanged for any choice of coordinate.

fn null_accumulator(line_size: u32) -> Self::AccumulatorItem

A accumulator such that Self::fuse_accumulators(accumulator, Self::null_accumulator() always returns is guaranteed to return accumulator unchanged.

fn assign_accumulator( destination: &mut Self::AccumulatorItem, source: &Self::AccumulatorItem, )

Assign the value of source into destination. In spirit, this is equivalent to destination = source;, but this syntax is not currently supported by CubeCL.

fn reduce( accumulator: &Self::AccumulatorItem, item: Line<In>, coordinate: Line<u32>, use_planes: bool, ) -> Self::AccumulatorItem

If use_planes is true, reduce all the item and coordinate within the accumulator. Else, reduce the given item and coordinate into the accumulator.

fn fuse_accumulators( lhs: Self::AccumulatorItem, rhs: Self::AccumulatorItem, ) -> Self::AccumulatorItem

Reduce two accumulators into a single accumulator.

fn merge_line<Out: Numeric>( accumulator: Self::AccumulatorItem, _shape_axis_reduce: u32, ) -> Out

Reduce all elements of the accumulator into a single output element of type Out.

fn to_output_perpendicular<Out: Numeric>( accumulator: Self::AccumulatorItem, _shape_axis_reduce: u32, ) -> Line<Out>

Convert each element of the accumulator into the expected output element of type Out.
