在 docker 中运行一个 mpi 应用程序

Question

我正在使用 docker，我希望能够在其中启动一个 mpi 应用程序。

我正在使用 ubuntu:latest 作为基本映像，并且我已经安装了编译我的程序并将其与 mpi 链接所需的工具。

当我使用 mpirun 启动程序时，我收到以下警告：

[c1dab84c3fac:10417] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file ess_hnp_module.c at line 170
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_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):

orte_plm_base_select failed
  --> Returned value Not found (-13) instead of ORTE_SUCCESS

如果我在普通的 ubuntu（相同版本）中运行相同的程序，它就会运行。

Answer 1

我最近遇到了这个问题。安装 ssh 包将解决此问题。

Answer 2

Docker 容器不像普通的 Ubuntu。默认的 Ubuntu 容器缺少一些基本的东西（例如：init、ssh daemon、cron）

通常我使用 phusion base-image docker，转到如下所示以了解有关默认 Ubuntu docker 中的一些基本问题以及如何解决这些问题的更多信息。
