我正在尝试构建一个基于Windows XP的简单集群。我成功编译了OpenMPI-1.4.2，像mpicc和ompi_info这样的工具也可以工作，但我无法使mpirun正常工作。我能看到的唯一输出是
Z:\>orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library. Error code = -2147417850 [host0:04728] [[8946,0],0] ORTE_ERROR_LOG: Error in file ..\..\openmpi-1.4.2 \orte\mca\ess\hnp\ess_hnp_module.c at line 218 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort.

z:\hosts.txt出现如下：
host0 host1
Z:是host0和host1均可使用的共享网络驱动器。
我的问题是什么，我该如何解决？
UPD： 好的，这个问题似乎已得到解决。在我看来，WideCap驱动程序和/或软件组件会导致出现此错误。 “干净”的机器成功运行本地任务。无论如何，我仍然无法在至少2台机器上运行任务，我收到以下消息：
Z:\>mpirun --hostfile z:\hosts.txt -np 2 hostname connecting to host1 username:MAIN\cluster password:******** Save Credential?(Y/N) y [host0:04728] This feature hasn't been implemented yet.

Error code =-2147217400 -------------------------------------------------------------------------- mpirun was unable to start the specified application as it encountered an error.

我用Google搜索了一下，完成了这里描述的所有事情：http://www.open-mpi.org/community/lists/users/2010/03/12355.php但我仍然遇到同样的错误。任何人都可以帮助我吗？
UPD2：
错误代码-2147217400可能是WMI错误WBEM_E_INVALID_PARAMETER (0x80041008)，它在传递给WMI调用的其中一个参数不正确时发生。这是否意味着问题出在OpenMPI源代码本身？或者也许是因为我从源代码构建OpenMPI时使用的错误/过时wincred.h和credui.lib？
