◆ Flagged() [1/2]

template<typename InputIteratorT , typename FlagIterator , typename OutputIteratorT , typename NumSelectedIteratorT >

__host__ static __forceinline__ hipError_t hipcub::DevicePartition::Flagged ( void *  d_temp_storage, size_t &  temp_storage_bytes, InputIteratorT  d_in, FlagIterator  d_flags, OutputIteratorT  d_out, NumSelectedIteratorT  d_num_selected_out, int  num_items, hipStream_t  stream = 0, bool  debug_synchronous = false  )

Parameters

[in]	d_temp_storage	Device-accessible allocation of temporary storage. When NULL, the required allocation size is written to temp_storage_bytes and no work is done.
[in,out]	temp_storage_bytes	Reference to size in bytes of d_temp_storage allocation
[in]	d_in	Pointer to the input sequence of data items
[in]	d_flags	Pointer to the input sequence of selection flags
[out]	d_out	Pointer to the output sequence of partitioned data items
[out]	d_num_selected_out	Pointer to the output total number of items selected (i.e., the offset of the unselected partition)
[in]	num_items	Total number of items to select from
[in]	stream	[optional] hip stream to launch kernels within. Default is stream0.
[in]	debug_synchronous	[optional] Whether or not to synchronize the stream after every kernel launch to check for errors. May cause significant slowdown. Default is false.

◆ If() [1/2]

template<typename InputIteratorT , typename OutputIteratorT , typename NumSelectedIteratorT , typename SelectOp >

__host__ static __forceinline__ hipError_t hipcub::DevicePartition::If ( void *  d_temp_storage, size_t &  temp_storage_bytes, InputIteratorT  d_in, OutputIteratorT  d_out, NumSelectedIteratorT  d_num_selected_out, int  num_items, SelectOp  select_op, hipStream_t  stream = 0, bool  debug_synchronous = false  )

[in,out]	temp_storage_bytes	Reference to size in bytes of d_temp_storage allocation
[in]	d_in	Pointer to the input sequence of data items
[out]	d_out	Pointer to the output sequence of partitioned data items
[out]	d_num_selected_out	Pointer to the output total number of items selected (i.e., the offset of the unselected partition)
[in]	num_items	Total number of items to select from
[in]	select_op	Unary selection operator
[in]	stream	[optional] hip stream to launch kernels within. Default is stream0.
[in]	debug_synchronous	[optional] Whether or not to synchronize the stream after every kernel launch to check for errors. May cause significant slowdown. Default is false.
