atomic_[op]

Header File: <Kokkos_Core.hpp>

Usage

atomic_[op](ptr_to_value,update_value);

Atomically updates the value at the address given by ptr_to_value with update_value according to the relevant operation.

Description

template<class T>
void atomic_add(T *const ptr_to_value, const T value);

Atomically executes *ptr_to_value += value.

• ptr_to_value: address of the to be updated value.

• value: value to be added.

template<class T>
void atomic_and(T *const ptr_to_value, const T value);

Atomically executes *ptr_to_value &= value.

• ptr_to_value: address of the to be updated value.

• value: value with which to combine the original value.

template<class T>
void atomic_decrement(T *const ptr_to_value);

Atomically executes (*ptr_to_value)-- or calls atomic_fetch_sub(ptr_to_value, T(-1)).

• ptr_to_value: address of the to be updated value.

template<class T>
void atomic_increment(T *const ptr_to_value);

Atomically executes (*ptr_to_value)++ or calls atomic_fetch_add(ptr_to_value, T(1)).

• ptr_to_value: address of the to be updated value.

template<class T>
void atomic_max(T *const ptr_to_value, const T value);

Atomically executes if (value > *ptr_to_value) *ptr_to_value = value.

• ptr_to_value: address of the to be updated value.

• value: value which to take the maximum with.

template<class T>
void atomic_min(T *const ptr_to_value, const T value);

Atomically executes if (value < *ptr_to_value) *ptr_to_value = value.

• ptr_to_value: address of the to be updated value.

• value: value which to take the minimum with.

template<class T>
void atomic_or(T *const ptr_to_value, const T value);

Atomically executes *ptr_to_value |= value.

• ptr_to_value: address of the to be updated value.

• value: value with which to combine the original value.

template<class T>
void atomic_sub(T *const ptr_to_value, const T value);

Atomically executes *ptr_to_value -= value.

• ptr_to_value: address of the to be updated value.

• value: value to be subtracted.
