Detailed Description

Implementation of the Communication Manager for the OpenCL backend.

Constructor & Destructor Documentation

◆ CommunicationManager()

HiCR::backend::opencl::CommunicationManager::CommunicationManager ( const std::unordered_map< opencl::Device::deviceIdentifier_t, std::shared_ptr< cl::CommandQueue > > & deviceQueueMap )

inline

Constructor for the opencl communication manager class for the OpenCL backend.

Parameters

[in] deviceQueueMap map of device ids and command queues

◆ ~CommunicationManager()

HiCR::backend::opencl::CommunicationManager::~CommunicationManager ( )

virtualdefault

Default destructor

Reimplemented from HiCR::CommunicationManager.

Member Function Documentation

◆ memcpyAsync()

__INLINE__ void HiCR::backend::opencl::CommunicationManager::memcpyAsync	(	const std::shared_ptr< HiCR::LocalMemorySlot > &	destination,
		const size_t	dst_offset,
		const std::shared_ptr< HiCR::LocalMemorySlot > &	source,
		const size_t	src_offset,
		const size_t	size,
		const cl::CommandQueue *	queue
	)

inline

Backend-internal asyncrhonous implementation of the memcpy operation. It passes an OpenCL stream as context for later asynchrounous check for completion
