如何将文件从一个进程传输到所有其他的mpi？ [英] how can i transfer file from one proccess to all other with mpi?

问题描述

我有一个文本文件，只在一台计算机上可用，我需要其他计算机能够读取该文件。
如何使用mpich2（c ++）发送文件？

I have a text file that is available on one computer only and I need the other computers to be able to read that file too. How can I send a file using mpich2 (c++)?

我尝试使用 MPI_File_open（）但似乎所有的计算机都需要该文件本地工作。 p>

I tried using MPI_File_open() but it seems that all the computers need that file locally to work.

推荐答案

所以我最终读取文件广播到其余的进程作为一个字符数组。
