Member Function Documentation

template<typename T >

void skepu::DeviceAllocations_CU< T >::addAllocation	(	void *	datapointer,
		MemPointerBase *	device_mem_pointer,
		int	deviceid
	)

Add a device memory allocation to the list

Parameters

datapointer	Pointer to device memory
device_mem_pointer	DeviceMemPointer_CU object related to the memory allocation
deviceid	ID of device where the allocation resides

Referenced by skepu::DeviceMemPointer_CU< T >::DeviceMemPointer_CU().

template<typename T >

bool skepu::DeviceAllocations_CU< T >::freeAllocation	(	size_t	minsize,
		int	deviceid
	)

Attempts to free up memory on the device Called when memory allocation fails due to lack of memory

Parameters

minsize	The amount of memory required by the failed malloc call
deviceid	The device to free up memory on
