Functions

template<typename T, class OP, class = Require<std::is_floating_point_v<T>>> __device__ void AtomicOp (T *address, T val, OP op)

Metafunction to do a generic atomic operation in floating-point types.

Template Parameters:

• T – Type of the values used in the atomic operation.

• OP – Operation class that defines the operator call to be used as atomics.

Parameters:

• address – [inout] First value to be used in the atomic operation.

• val – [in] Second value to be used.

• op – [in] Operation to be used.

template<typename T> inline __device__ void AtomicMin (T &a, T b)

Metafunction to do a atomic minimum operation that accepts floating-point types.

Template Parameters:

T – Type of the values used in the atomic operation.

Parameters:

• a – [inout] First value to be used in the atomic operation.

• b – [in] Second value to be used.

template<typename T> inline __device__ void AtomicMax (T &a, T b)

Metafunction to do a atomic maximum operation that accepts floating-point types.

Template Parameters:

T – Type of the values used in the atomic operation.

Parameters:

• a – [inout] First value to be used in the atomic operation.

• b – [in] Second value to be used.
