我有两台机器都安装了MS MPI 7.1，一台名为SERVER，另一台名为COMPUTE。 这些机器在一个简单的Windows工作组（无DA）中设置在局域网上，并且都有一个具有相同名称和密码的帐户。MS MPI权限错误
两者都运行MSMPILaunchSvc服务。 两种机器可以在本地执行MPI作业，通过在上机器本身的终端与hostname命令
SERVER> mpiexec -hosts 1 SERVER 1 hostname
SERVER
or
COMPUTE> mpiexec -hosts 1 COMPUTE 1 hostname
COMPUTE
测试验证。
我已经禁用了两台机器上的防火墙，以使事情更轻松。
我的问题是我不能让MPI到远程主机上运行的服务器作业：
1：MSMPILaunchSvc服务器 - >计算与MSMPILaunchSvc
SERVER> mpiexec -hosts 1 COMPUTE 1 hostname -pwd
ERROR: Failed RpcCliCreateContext error 1722
Aborting: mpiexec on SERVER is unable to connect to the smpd service on COMPUTE:8677
Other MPI error, error stack:
connect failed - The RPC server is unavailable. (errno 1722)
什么是更令人沮丧这里仅在有时候我会提示输入密码。它建议SERVER \ Maarten作为COMPUTE的用户，我已经在SERVER上登录帐户，并且不应该存在于COMPUTE（应该是COMPUTE \ Maarten然后？）。然而它也失败：
SERVER>mpiexec -hosts 1 COMPUTE 1 hostname.exe -pwd
Enter Password for SERVER\Maarten:
Save Credentials[y|n]? n
ERROR: Failed to connect to SMPD Manager Instance error 1726
Aborting: mpiexec on SERVER is unable to connect to the
smpd manager on COMPUTE:50915 error 1726
2：用MSMPILaunchSvc COMPUTE - >服务器MSMPILaunchSvc
COMPUTE> mpiexec -hosts 1 SERVER 1 hostname -pwd
ERROR: Failed RpcCliCreateContext error 5
Aborting: mpiexec on COMPUTE is unable to connect to the smpd service on SERVER:8677
Other MPI error, error stack:

3：计算与MSMPILaunchSvc - >服务器SMPD守护程序
Aborting: mpiexec on COMPUTE is unable to connect to the smpd service on SERVER:8677
Other MPI error, error stack:
connect failed - Access is denied. (errno 5)
4：带有MSMPILaunchSvc的服务器 - >带有smpd守护程序的计算机
ERROR: Failed to connect to SMPD Manager Instance error 1726
Aborting: mpiexec on SERVER is unable to connect to the smpd manager on
COMPUTE:51022 error 1726
更新：
两个节点上SMPD守护尝试我得到这个错误：
