MergeSort algorithm is a good candidate to parallelize, especially the first step where each thread can sort a separate partition independently then merging all these sorted partitions together to get the full array sorted. Assuming the array length is N, it will be divided into M partitions P1,...

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...
parallel append merge 多段并行执行并且排序 例如分区表的操作,当一个QUERY涉及多个分区时,每个分区的执行部分为一个独立段,多个分区可以并行执行,优化器支持结果并行 append。 如果多段执行的结果需要排序,那么优化器可以在每个段内返回有序结果,可以使用归并排序(类似merge sort, gather merge)(parallel append merge...
默认值为PARALLEL_THREADS_PER_CPU * CPU_COUNT * concurrent_parallel_users * 5。该参数确定一个实例并行执行进程和并行恢复进程的最大数。当需求增加时,Oracle数据库从实例启动时的进程数增加到该参数值。在默认值计算公式中,实例上赋予正在使用的concurrent_parallel_users的值和内存管理设置相关。如果自动内存管理...
