此函数语义与 std::sort 相似,因为它是基于比较、不稳定、就地排序的。 复制 template< typename _Random_iterator > inline void parallel_sort( const _Random_iterator &_Begin, const _Random_iterator &_End ); template< typename _Random_iterator, typename _Function > inline void parallel_sort( ...
Hmm, apparently parallel_sort is currently implemented with parallel_for and a weird-looking quick_sort_range class that does the partitioning... and has a "grainsize" parameter. That's either really neat, because it follows naturally from the quicksort algorithm and uses only high-level constr...

Parallel Sort Parallel Sort https://ac.nowcoder.com/acm/contest/14055/K 题意:给定长度为n的排列,一次操作你可以选择任意个下标数对:(x1,y1),(x2,y2),…(xn,yn)。 要求每个下标最多只出现一次。问最少需要几次操作能够将排列恢复为原排列,同时输出每次操作选择的下标。
I'm using tbb::parallel_sort to sort a vector of about 300,000 elements. This operation happens quite often across several machines and every now and
parallel-sort欣妹**欣妹 上传409.62 KB 文件格式 zip 双调排序是一种并行排序算法,可通过指令级并行和线程级并行进行优化。在指令级并行中,可以利用SIMD指令集(如SSE、AVX等)同时处理多个数据元素,提高排序速度。而线程级并行则可以将排序任务分配给多个线程,每个线程负责处理一部分数据,从而充分利用多核处理器的...
Question: if there are 10,000,000 integers that need to be sorted in parallel, would you use parallel sort? When would you use parallel buffered sort instead of parallel sort? Since the type is integral, is parallel radix sort the best option for this case? What if you are trying to ...
should i improve the extra allocation in beginning of sort For current CT for tpch/16.sql, there is a sortAlloc span in timeline. Should i do something to improve it. Maybe we don't need a large toSort vector, but have serveral small vectors that are allocated by SortCopyTask run. Th...
