环境变量配置错误，报错：*/help-opal-runtime.txt: No such file or directory.

现象描述

用户集群环境配置问题导致mpirun命令在集群环境中运行失败。

运行失败示例如下：

mpirun ~/AllReduce

-------------------------------------------------------------------------- 
Sorry!  You were supposed to get help about: 
    opal_init:startup:internal-failure 
But I couldn't open the help file: 
    /usr1/workspace/Version_pipeline_ompi_aarch64_gccx.x.x_CentOS7.6_MLX4.9/ompi/build/../share/openmpi/help-opal-runtime.txt: No such file or directory.  Sorry! 
--------------------------------------------------------------------------

可能原因

“.bashrc”文件未配置“OPAL_PREFIX”环境变量。

恢复步骤

使用PuTTY工具，以Hyper MPI普通用户（例如“hmpi_user”）登录至作业执行节点。
按照设置环境变量修改“.bashrc”文件，配置环境变量。
