访问邻居 PC 零售商店提供了充足的证据，我们是在多核时代。厂商之间的关键区别今天是他们打包到单个芯片上的内核的数量。商品处理器的时钟频率已经达到了极限，然而，和很可能保持在以下 4 GHz 多年来。因此，加入内核是不增加计算能力的代名词。要充分利用提供的新的多核硬件的性能增强，相应地调整必须发生在软件基础设施 — — 转变为并行计算。

设计MPI程序模拟广播（MPI_Bcast）操作：将每个MPI进程按照所在节点名称建立node通信子域分组；再将各个node子通信域的0号进程再次组成一个名为head的通信域；在进行广播时，首先，由root进程将消息在head通信子域内广播，然后，再由head子域内各进程在其所在的node子域内进行广播。(Design the MPI program MPI_Bcast operation: Each MPI process establishes a node communication sub-domain grouping according to the node name; then, each process of the 0 node of each node sub-communication domain is again formed into a communication domain named head; At first, the root process broadcasts the message in the head communication sub-domain, and then the processes in the head sub-domain broadcast in the node sub-domain where it is)

利用Python实现特征的MinMax标准化和Z-Score标准化两种特征归一化方法。并用原特征、两种归一化特征分别进行模型训练，比较模型性能。(Two normalization methods of MinMax normalization and Z-Score standardization are implemented by Python. The model is trained by the original feature and two normalization features respectively, and the performance of the model is compared.)
