在 Windows XP 上运行 OpenMPI

Question

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，并且 mpicc 和 ompi_info 等工具也可以工作，但我无法让我的 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

It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_plm_init failed
  --> Returned value Error (-1) instead of ORTE_SUCCESS

z:\hosts.txt 如下所示：

host0
host1

Z: 是一个可供 host0 和 host1 使用的共享网络驱动器。

我的问题是什么以及如何解决它？

更新： 好的，这个问题似乎已经解决了。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。不管怎样，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.
[host0:04728] Could not connect to namespace cimv2 on node host1. Error code =-2147217400

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

我用 google 搜索了一下并按照此处所述执行了所有操作： http://www.open-mpi.org/community/lists/users/2010/03/12355.php 但我仍然遇到同样的错误。有人可以帮助我吗？

更新2： 错误代码 -2147217400 可能是 WMI 错误 WBEM_E_INVALID_PARAMETER (0x80041008)，当传递到 WMI 调用的参数之一不正确时，就会发生该错误。这是否意味着问题出在 OpenMPI 源代码本身？或者可能是因为我在从源代码构建 OpenMPI 时使用了错误/过时的 wincred.h 和 credui.lib ？
