在计算机上执行mpjboot时出现此错误

问题描述

我在环境变量中设置了MPJ_HOME，执行mpjboot机器时出现此错误

i set MPJ_HOME in the environment variable and when i execute mpjboot machines i get this error

Error: MPJ_HOME environment variable not set!!!

java.lang.Exception: MPJ_HOME environment variable not set!!!

at runtime.daemon.MPJDaemon.<init>(MPJDaemon.java:87)



at runtime.daemon.MPJDaemon.main(MPJDaemon.java:252)

[server] Unable to start MPJ Express daemon

推荐答案

MPJDaemon类在计算节点上执行，它侦听来自mpirun模块的请求(在主机上运行)

MPJDaemon class is executed on compute nodes, it listens for the requests from mpirun module (running on head machine)

请确保在计算机文件中列出的所有计算节点中都设置了MPJ_HOME变量

Please make sure that MPJ_HOME variable is set in all compute nodes you listed in machines file
