Constructor & Destructor Documentation

Bitset() [1/2]

template<typename Device >

Kokkos::Bitset< Device >::Bitset ( unsigned  arg_size )

inline

arg_size := number of bit in set

Definition at line 79 of file Kokkos_Bitset.hpp.

Bitset() [2/2]

template<typename Device >

template<class... P>

Ensure that allocation properties are consistent.

Update 'label' property and allocate.

Member Function Documentation

size()

template<typename Device >

KOKKOS_FORCEINLINE_FUNCTION unsigned Kokkos::Bitset< Device >::size ( ) const

inline

number of bits in the set can be call from the host or the device

Definition at line 121 of file Kokkos_Bitset.hpp.

count()

template<typename Device >

unsigned Kokkos::Bitset< Device >::count ( ) const

inline

number of bits which are set to 1 can only be called from the host

Definition at line 125 of file Kokkos_Bitset.hpp.

set() [1/2]

template<typename Device >

void Kokkos::Bitset< Device >::set ( )

inline

set all bits to 1 can only be called from the host

Definition at line 132 of file Kokkos_Bitset.hpp.

reset() [1/2]

template<typename Device >

void Kokkos::Bitset< Device >::reset ( )

inline

set all bits to 0 can only be called from the host

Definition at line 148 of file Kokkos_Bitset.hpp.

clear()

template<typename Device >

void Kokkos::Bitset< Device >::clear ( )

inline

set all bits to 0 can only be called from the host

Definition at line 152 of file Kokkos_Bitset.hpp.

set() [2/2]

template<typename Device >

KOKKOS_FORCEINLINE_FUNCTION bool Kokkos::Bitset< Device >::set ( unsigned  i ) const

inline

set i'th bit to 1 can only be called from the device

Definition at line 157 of file Kokkos_Bitset.hpp.

reset() [2/2]

template<typename Device >

KOKKOS_FORCEINLINE_FUNCTION bool Kokkos::Bitset< Device >::reset ( unsigned  i ) const

inline

set i'th bit to 0 can only be called from the device

Definition at line 170 of file Kokkos_Bitset.hpp.

test()

template<typename Device >

KOKKOS_FORCEINLINE_FUNCTION bool Kokkos::Bitset< Device >::test ( unsigned  i ) const

inline

return true if the i'th bit set to 1 can only be called from the device

Definition at line 183 of file Kokkos_Bitset.hpp.

max_hint()

template<typename Device >

KOKKOS_FORCEINLINE_FUNCTION unsigned Kokkos::Bitset< Device >::max_hint ( ) const

inline

used with find_any_set_near or find_any_unset_near functions returns the max number of times those functions should be call when searching for an available bit

Definition at line 200 of file Kokkos_Bitset.hpp.

find_any_set_near()

template<typename Device >

KOKKOS_INLINE_FUNCTION Kokkos::pair< bool, unsigned > Kokkos::Bitset< Device >::find_any_set_near ( unsigned  hint, unsigned  scan_direction = BIT_SCAN_FORWARD_MOVE_HINT_FORWARD  ) const

inline

find a bit set to 1 near the hint returns a pair< bool, unsigned> where if result.first is true then result.second is the bit found and if result.first is false the result.second is a new hint

Definition at line 207 of file Kokkos_Bitset.hpp.

find_any_unset_near()

template<typename Device >

KOKKOS_INLINE_FUNCTION Kokkos::pair< bool, unsigned > Kokkos::Bitset< Device >::find_any_unset_near ( unsigned  hint, unsigned  scan_direction = BIT_SCAN_FORWARD_MOVE_HINT_FORWARD  ) const

inline

find a bit set to 0 near the hint returns a pair< bool, unsigned> where if result.first is true then result.second is the bit found and if result.first is false the result.second is a new hint

Definition at line 230 of file Kokkos_Bitset.hpp.
