Constructor & Destructor Documentation

Kernel()

Kernel::Kernel	(	std::shared_ptr< char[]>	ptx,
		std::string	demangled_name
	)

create a Kernel based on a templated kernel string

Parameters

ptx
kernel_name
demangled_name

Member Function Documentation

benchmark()

std::vector< KernelTime > Kernel::benchmark	(	KernelArgs	args,
		unsigned int	executions,
		Device &	device = Devices::findDevice()
	)

benchmark a Kernel

Parameters

kernel_args
number	of executions
device

Returns

vector of KernelTimes for every execution

		unsigned int	shared = 0
	)

Parameters

grid	vector of grid dimensions
block	vector of block dimensions
shared	amount of dynamic shared memory to allocate

Returns

this (for method chaining)
