DCOM和OpenMPI

Question

我使用启动和远程访问权限执行DCOMCNFG，在每个节点上授予我的本地登录权限。在根计算机和远程计算机上安装OpenMPI_v1.6.1-x64。HAve指定了目标节点中.exe的路径。而是在使用mpirun从根节点运行.exe时。我收到以下错误：

D:\x64\Release>mpirun -np 2 -hostfile myhostfile.txt MPISample.exe
connecting to n1234
username:toney.mathew
password:********
Save Credential?(Y/N) n
[n1205:04420] Could not connect to namespace cimv2 on node n1234. Error code =-2147023174

mpirun was unable to start the specified application as it encountered an error.

More information may be available above.

更具体地说，我在两个节点上使用Windows7-64位操作系统，使用相同的用户登录。

关闭了防火墙，运行起来很顺畅。
