书中第一部分简单介绍了并行程序设计的基本知识；然后在第二部分介绍基本的MPI并行程序设计方法，它虽然基本，但是却非常重要，因为通过这部分介绍的功能，可以实现几乎所有的通信功能；第三部分是在第二部分的基础上，介绍高级、复杂的MPI并行程序设计，使用高级的MPI调用可以提高并行程序的通用性和移植性，对提高并行程序的开发效率、可读性以及并行程序的执行效率等都有好处；最后一部分介绍MPI的最新扩展MPI-2，着重对动态进程管理、远程存储访问和并行I/O进行了讲解。-The book first section briefly describes the basic knowledge of parallel programming　and then in the second section describes the basic design of MPI parallel programming method, which although essential, but it is very important, because through this section describes the functions, you can achieve almost all of the communication function　The third part is the second part of the basis, introducing high-level, complex MPI parallel programming, the use of high-level parallel programming MPI calls can increase the versatility and portability of parallel programs to improve development efficiency can be Reading sex, as well as the efficiency of parallel implementation of the procedures and so good　last part of the MPI introduced the latest expansion of MPI-2, focused on dynamic process management, remote memory access and parallel I/O was explained.
