Function Documentation

binary_cast()

template<typename Out , typename In >

CUGAR_FORCEINLINE CUGAR_HOST_DEVICE Out cugar::binary_cast

(

const In

in

)

a utility to perform binary casts between different types

count_occurrences()

template<typename Iterator , typename T >

CUGAR_FORCEINLINE CUGAR_HOST_DEVICE uint32 cugar::count_occurrences	(	const Iterator	begin,
		uint32	size,
		const T	val,
		const uint32	max_occ = uint32(-1)
	)

count the number of occurrences of a given value inside an array, up to a maximum value

divide_ri()

template<typename L , typename R >

CUGAR_HOST_DEVICE L cugar::divide_ri ( const L  x, const R  y  )

inline

x/y rounding towards +infinity for integers, used to determine # of blocks/warps etc.

divide_rz()

template<typename L , typename R >

CUGAR_HOST_DEVICE L cugar::divide_rz ( const L  x, const R  y  )

inline

x/y rounding towards zero for integers, used to determine # of blocks/warps etc.

hi_bits()

template<uint32 N>

CUGAR_FORCEINLINE CUGAR_HOST_DEVICE uint32 cugar::hi_bits

(

)

return the bitmask with the hi N bits set

lo_bits()

template<uint32 N>

CUGAR_FORCEINLINE CUGAR_HOST_DEVICE uint32 cugar::lo_bits

(

)

return the bitmask with the lo N bits set

round()

template<typename L , typename R >

CUGAR_HOST_DEVICE L cugar::round ( const L  x, const R  y  )

inline

round x towards to the closest multiple of x

round_i()

template<typename L , typename R >

CUGAR_HOST_DEVICE L cugar::round_i ( const L  x, const R  y  )

inline

round x towards infinity to the next multiple of y

round_z()

template<typename L , typename R >

CUGAR_HOST_DEVICE L cugar::round_z ( const L  x, const R  y  )

inline

round x towards zero to the next multiple of y
