Description: 并行计算程序
Description: This program blurs an image file in a parallelized computation
The root process reads the file and distributes a part of the image file to
other processes. Each process makes the filter operation on the part of the image data which is received from the root. Then all the processes send their blurred image data to the root and root writes the result in a file-Distributed Image Processing Filter
Write a program that blurs an image file in a parallelized computation. Whenever possible, use collective
operations (MPI_Scatter, MPI_Gather). The root process reads the image file from the NFS
server, distributes the data of the file among all processes, and gathers the results into the output file.
Each processor should receive a part of the image only. The image file is provided as a raw image file.
It can be read using the C function fread() with a single call and written with the single call of the
function fwrite(). The image is given as an array of h rows, a row has 1280 pixels , where each pixel
is one unsigned char grey value. You may assume that h is lower than or equal to 8192.
a) Write an MPI program in which the root process prepairs the data, so that all other processes
get their data by exactly one MPI_Scatter operation.

Description: Siemens PPI协议分析
西门子S7-200 PLC之间或者PLC与PC之间通信有很多种方式:自由口，PPI方式，MPI方式，Profibus方式。使用自由口方式进行编程时，在上位机和PLC中都要编写数据通信程序。使用PPI协议进行通信时，PLC可以不用编程，而且可读写所有数据区，快捷方便。但是西门子公司没有公布PPI协议的格式。用户如果想使用PPI协议监控，必须购买其监控产品或第三方厂家的组态软件。这样给用户自主开发带来一定困难，特别是自行开发的现场设备就不能通过PPI协议接入PLC。其它通讯方式编程也存在编程复杂，需要购买软件和授权等局限性。通过数据监视、分析的方法，我们找出了PPI协议的关键报文格式，可用于上位机、现场设备与S7-200 CPU之间通讯。-Siemens PPI negotiates analysis
Siemens S7-200 PLCs it occasionally between PC and PLC the correspondence has a lot of methods: free orifice, PPI method, MPI method, Profibus method.Use free when the orifice method progress weave a distance all want to write data correspondence procedure in the place of honor machine and PLC.While using PPI to negotiate progress correspondence PLC can need not plait distance, and can read and write all data zones, fast convenience.But Siemens company didn t release PPI the format of agreement.If the consumer wants to use PPI to negotiate supervision, has to buy the configuration software that it supervises and controls a product or third party plant house.Give the consumer independent tapping fetch must be difficult like this, develop especially and by oneself of site equipment the incapability negotiate connecting through PPI into PLC.Other telecommunication methods
