我有兩臺機器都安裝了MS MPI 7.1，一臺名爲SERVER，另一臺名爲COMPUTE。 這些機器在一個簡單的Windows工作組（無DA）中設置在局域網上，並且都有一個具有相同名稱和密碼的帳戶。MS MPI權限錯誤
兩者都運行MSMPILaunchSvc服務。 兩種機器可以在本地執行MPI作業，通過在上機器本身的終端與hostname命令
SERVER> mpiexec -hosts 1 SERVER 1 hostname
SERVER
or
COMPUTE> mpiexec -hosts 1 COMPUTE 1 hostname
COMPUTE
測試驗證。
我已經禁用了兩臺機器上的防火牆，以使事情更輕鬆。
我的問題是我不能讓MPI到遠程主機上運行的服務器作業：
1：MSMPILaunchSvc服務器 - >計算與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)
什麼是更令人沮喪這裏僅在有時候我會提示輸入密碼。它建議SERVER \ Maarten作爲COMPUTE的用戶，我已經在SERVER上登錄帳戶，並且不應該存在於COMPUTE（應該是COMPUTE \ Maarten然後？）。然而它也失敗：
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 - >服務器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:
connect failed - Access is denied. (errno 5)
3：計算與MSMPILaunchSvc - >服務器SMPD守護程序
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：帶有MSMPILaunchSvc的服務器 - >帶有smpd守護程序的計算機
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：
兩個節點上SMPD守護嘗試我得到這個錯誤：
