Detailed Description

template<typename T, bool Zero>
class sp::LazyGpuBuffer< T, Zero >

A buffer that is lazily-allocated using double-checked locking.

Template Parameters

Zero	Zero-fill the buffer when it is allocated.

Constructor & Destructor Documentation

LazyGpuBuffer()

template<typename T , bool Zero>

sp::LazyGpuBuffer< T, Zero >::LazyGpuBuffer	(	Stream &	s,
		int	bufferSize
	)

Initialise a LazyGpuBuffer that will be the given size when eventually allocated, associated with a stream.

Member Function Documentation

get()

template<typename T , bool Zero>

__device T * sp::LazyGpuBuffer< T, Zero >::get

(

)

Get the buffer.

If the buffer hasn't been allocated yet, it is allocated and possibly zero-initialised. It's very cheap after the first time (which is quite slow).
