给一个长度为 n 的乱序数组,将其排序,考虑merge-sort算法,需要 log2n 轮排序,第一轮排序需要将n/2 个pairs 比较排序,第二轮需要将 n/4 个pairs 排序,最后一轮将 2 个pairs 排序生成单独的排序数组。 考虑使用并行merge-sort算法,使用 p 核计算机,假设 n>>p ,在前面的轮次,每个核可以负责一批 pairs 的...

分为几个阶段,一个线程能hold住的阶段,一个block能hold住的阶段(task per block), final merge 这里有个问题,如何parallel merge? 例如两个有序array合并。 每一个array已经知道它自己的index,然后去其他array二分查找其lower_bound即可。 然而,merge sort最难的是final merge,大量的数据,batch数量很少。如何将其...

As a result, OpenMP exclusively supports parallel reductions over commutative monoids where a∘b=b∘a for every pair of two values in M. Actually, we will later show in this section that even static schedules compute incorrect results on non-commutative monoids. Show moreView chapter...
On the other side, OpenMP is an example of mainly implicit parallel API intended for shared-memory multiprocessors [14]. It exploits parallelism through compiler directives and the library function calls. Unlike MPI, where all threads are spawned at the beginning of the execution and are active ...
