\internal_

Returns the default context for the system. The default context is created for the default device on the system (as returned by default_device()). T

Returns the default compute device for the system. The default device is selected based on a set of heuristics and can be influenced using one of the

Creates a null device object.

Returns the number of devices on the platform.

Returns a list of devices on the platform.

Generates \p z random numbers and discards them.

Returns the driver version string.

Creates a new dynamic bitset with storage for \p size bits. Initializes all bits to zero.

Converts an \c Eigen::Matrix4d to a \c double16_.

Returns \c true if the dynamic bitset is empty (i.e. \c size() == \c 0).

Returns \c true if the mapped_view is empty.

Returns \c true if the wait-list is empty.

Returns an iterator to one past the last element in the mapped_view.

Enqueues a barrier in the queue.

Enqueues a command to copy a rectangular region from \p src_buffer to \p dst_buffer. \see_opencl_ref{clEnqueueCopyBufferRect} \opencl_version_warnin

Enqueues a command to copy data from \p src_buffer to \p dst_image. \see_opencl_ref{clEnqueueCopyBufferToImage}

Enqueues a command to copy data from \p src_image to \p dst_buffer. \see_opencl_ref{clEnqueueCopyImageToBuffer}

Enqueues a command to map \p buffer into the host address space. Map operation is performed asynchronously. The pointer to the mapped region cannot be

Enqueues a command to read a rectangular region from \p buffer to host memory. \see_opencl_ref{clEnqueueReadBufferRect} \opencl_version_warning{1,1}
