cuda::experimental::logical_device

Defined in include/cuda/experimental/__device/logical_device.cuh

class logical_device

A non-owning representation of a CUDA device or a green context.

Public Types

enum class kinds

Enum to indicate the kind of logical device stored.

Values:

enumerator device

enumerator green_context

Public Functions

inline constexpr CUcontext context() const noexcept

inline constexpr device_ref underlying_device() const noexcept

Retrieve the device on which this logical device resides.

inline constexpr kinds kind() const noexcept

Retrieve the kind of logical device stored in this object The kind indicates if this logical_device holds a device or green_context.

inline explicit logical_device(int __id)

Construct logical_device from a device ordinal.

Constructing a logical_device for a given device ordinal has a side effect of initializing that device

inline explicit logical_device(device_ref __dev)

Construct logical_device from a device_ref.

Constructing a logical_device for a given device_ref has a side effect of initializing that device

inline logical_device(const ::cuda::physical_device &__dev)

Constructing a logical_device for a given device has a side effect of initializing that device.

inline logical_device(const green_context &__gctx)

Construct logical_device from a green_context.

Friends

inline friend bool operator==(logical_device __lhs, logical_device __rhs) noexcept

Compares two logical_devices for equality.

Parameters

• __lhs – The first logical_device to compare

• __rhs – The second logical_device to compare

Returns

true if lhs and rhs refer to the same logical device
