cub::TransformPolicy

struct TransformPolicy

The tuning policy for all algorithms in DeviceTransform.

Public Functions

inline friend ::std::ostream &operator<<(

::std::ostream &os,

const TransformPolicy &policy

)

Public Members

int min_bytes_in_flight

Minimum number of bytes in flight per SM to reach by scaling the items per thread.

Has no effect if algorithm is vectorized.

TransformAlgorithm algorithm

The transform algorithm to use by the kernel.

TransformPrefetchPolicy prefetch

Sub-policy for the prefetch algorithm.

Only used when algorithm is prefetch or when algorithm is vectorized and the input pointers are not sufficiently aligned.

TransformVectorizedPolicy vectorized

Sub-policy for the vectorized algorithm.

Only used when algorithm is vectorized.

TransformAsyncCopyPolicy async_copy

Sub-policy for the async copy algorithms.

Only used when algorithm is ldgsts or ublkcp.
