66 __TBB_ASSERT ( initial_segment && segment_size,
"Nonempty initial segment must be supplied");
size_t m_pos
Insertion position in m_cur_segment.
#define __TBB_ASSERT(predicate, comment)
No-op version of __TBB_ASSERT.
Smart holder for the empty task class with automatic destruction.
auto_empty_task(__TBB_CONTEXT_ARG(generic_scheduler *s, task_group_context *context))
Memory prefix to a task object.
size_t m_num_segments
Number of segments (the size of m_segments)
void push_back(const T &val)
size_t m_size
Number of items in the segments in m_segments.
Used to form groups of tasks.
Work stealing task scheduler.
@ small_local_task
Bitwise-OR of local_task and small_task.
void copy_memory(T *dst) const
Copies the contents of the vector into the dst array.
Base class for user-defined tasks.
size_t m_cur_segment_size
Capacity of m_cur_segment.
void free_task(task &t)
Put task on free list.
void const char const char int ITT_FORMAT __itt_group_sync s
fast_reverse_vector(T *initial_segment, size_t segment_size)
generic_scheduler * my_scheduler
T * m_segments[max_segments]
Array of segments (has fixed size specified by the second template parameter)
task that does nothing. Useful for synchronization.
Vector that grows without reallocations, and stores items in the reverse order.
void __TBB_EXPORTED_FUNC NFS_Free(void *)
Free memory allocated by NFS_Allocate.
internal::task_prefix & prefix(internal::version_tag *=NULL) const
Get reference to corresponding task_prefix.
T * m_cur_segment
The current (not completely filled) segment.
void *__TBB_EXPORTED_FUNC NFS_Allocate(size_t n_element, size_t element_size, void *hint)
Allocate memory on cache/sector line boundary.
