A first quicksort is performed in parallel across pairs of partitions based on a pivot using a plurality of processors. A second quicksort is performed in parallel on unsorted elements within each partition based on the pivot, where the unsorted elements were left unsorted by the first quick...
算法比较的是对两个vector进行快速排序,SerialQuickSort是常规的串行递归执行对这个两个DataContainer进行排序,ParallelQuickSort只是使用tbb::invoke函数并行的调用SerialQuickSort,对这两个DataContainer同时进行排序 在执行ParallelQuickSort之前,使用了一个小函数WarmupforParallel来进行TBB库的热身。 从结果上看,效率调高...
摘要: A parallel version of quicksort on a CRCW PRAM is developed. The algorithm uses n processors and a linear space to sort n keys in the expected time O (log n ) with large probability.关键词: Theoretical or Mathematical/ computational complexity parallel algorithms sorting/ parallel ...
As I mentioned in my previous post, Array.Parallel sort functions demonstrating a Merge Sort using Barrier, I wanted to continue the parallel sort examples with a Quicksort using the Task Parallel Libraries.F#, as do all functional languages, lend themselves easily to Quicksort implementations. ...
