Function scatter

function scatter(const T *, const vec<T, N> &) simd

template <size_t Index, size_t... Indices, typename T, size_t N, size_t InIndex = 0>
KFR_INTRINSIC void scatter(const T* base, const vec<T, N>& value)

Scatters elements of value to base at the given compile-time indices.

Template parameters
Index First compile-time destination index.
Indices Remaining compile-time destination indices.
T Element type.
N Input vector length.
InIndex Position within value to write next (defaults to 0).
Parameters
base Pointer to the destination array.
value Vector whose elements are written to base[Index], base[Indices]... in order.

Function scatter

function scatter(T *, const vec<IT, N> &, const vec<T, Nout> &) simd

template <size_t groupsize = 1, typename T, size_t N, size_t Nout = N * groupsize, typename IT>
KFR_INTRINSIC void scatter(T* base, const vec<IT, N>& offset, const vec<T, Nout>& value)

Scatters N groups of groupsize contiguous elements of value to base using a vector of offsets.

Template parameters
groupsize Number of contiguous elements per group.
T Element type.
N Number of offsets (and groups).
Nout Total number of elements to write (defaults to N*groupsize).
IT Offset integer type.
Parameters
base Pointer to the destination array.
offset Vector of offsets (in groups) into base.
value Vector whose elements are scattered to the destination groups.
