Emad Omara's parallel merge sort algorithm assumes that you will have full access to the machine's CPUs for the duration of the sorting operation.

Emad Omara的并行合并排序算法假设了在排序操作的过程中(操作者)对计算机的所有CPU具有完全的访问权限。

Merge-sort is not an inherently parallel algorithm, as it can be done sequentially, and is popular when the data set is too large to fit in memory and must be sorted in pieces.

合并排序本身并非并行算法，因为它可以顺序执行。 当数据集太大，内存无法容纳，必须分片保存的时候，经常使用合并排序。

PTSA provides many possible choices for all sub-projects in a project which will be arranged in serial or parallel way, so PTSA improves the applied value of Topological Sort Algorithm.

PTSA算法为工程中各子工程的串行或并行安排提供了确定的选择，提升了拓扑排序算法的实用价值。
