运行基于OpenMPI的库时出错 [英] Error when running OpenMPI based library

问题描述

我已经从Ubuntu中可用的标准apt-get安装程序安装了openmpi库.我运行一个调用MPI库的python代码.我收到以下错误.有什么想法是错误的根源吗?这是OpenMPI配置错误吗?该如何解决?

I have install openmpi library from the standard apt-get install available in Ubuntu. I run a python code which call MPI libraries. I get the following error. Any ideas whatis the source of error? Is it an OpenMPI configuration error? How to fix this?

--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):



     opal_shmem_base_select failed
      --> Returned value -1 instead of OPAL_SUCCESS

推荐答案

链接和加载方式似乎有些复杂.解决方案是使用--disable-dlopen

Seems to be a somewhat complex problem with linking and how modules are loaded. The solution is to compile openmpi with --disable-dlopen

使用--disable-mca-dso进行编译也对我有用.不幸的是，我不知道这在ubuntu上有多么容易.

Compiling with --disable-mca-dso also worked for me. Unfortunately, I don't know how easy this is on ubuntu.

请参见 http://www.open-mpi.org/常见问题解答/?category = building#avoid-dso
