Question

我已经从Ubuntu中提供的标准apt-get安装中安装了openmpi库。我运行一个调用MPI库的python代码。我收到以下错误。任何想法都是错误的来源？它是OpenMPI配置错误吗？如何解决这个问题？

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

链接以及如何加载模块似乎是一个有点复杂的问题。解决方案是使用--disable-dlopen

编译openmpi

使用--disable-mca-dso进行编译也对我有用。不幸的是，我不知道这对ubuntu来说有多容易。

请参阅http://www.open-mpi.org/faq/?category=building#avoid-dso

我在这里找到了解决方案：
