如何在visual studio中提供mpi命令行参数

问题描述

嘿伙计们我想知道有没有办法在visual studio中使用命令行参数给出mpi命令，因为我需要调试程序

Hey guys I wanted to know is there a way to give mpi commands using the command line arguments in visual studio because I need to debug the program

推荐答案

引用：

在Linux / Windows / Mac OSX上的大多数MPI实现中，你调用MPI_Init（& argc，& argv），修改参数列表，就好像你已经将序列问题作为程序10 10运行一样;它将参数列表放到可执行文件中，这可能包含mpirun命令本身的任意数量的选项。



标准没有指定这个;标准留下了很多关于启动进程和初始化过程的事情，因为MPI必须处理与POSIX类型系统行为非常不同的系统。但我从来没有在POSIX类型的环境中看到过没有这样做的MPI实现。

In most MPI implementations on Linux/Windows/Mac OSX, when you call MPI_Init(&argc, &argv), the argument list is modified just as if you had run the serial problem as program 10 10; it eats the argument list up to the executable, which can potentially contain any number of options to the mpirun command itself.

The standard doesn't specify this; the standard leaves a lot of things about launching processes and the initialization process somewhat vague, as MPI has to work on systems that behave very differently than POSIX-type systems. But I've never seen an MPI implementation in a POSIX-type environment that doesn't do this.
