带有mpi4py的Openmpi不能在多个节点上工作

Question

我有一个用mpi4py编写的并行python程序。我正在努力把它分发出去。我设置虚拟机，安装openmpi，openssh服务器，交换密钥等等。在本地计算机上我有主机文件：

127.0.0.1 slots=4
192.168.1.104 slots=2

我试着用：

^{pr2}$

但我得到了以下错误：

[Kreutz:13090] tcp_peer_recv_connect_ack: invalid header type: 0

ORTE was unable to reliably start one or more daemons. This usually is caused by:

• not finding the required libraries and/or binaries on one or more nodes. Please check your PATH and LD_LIBRARY_PATH settings, or configure OMPI with --enable-orterun-prefix-by-default

• lack of authority to execute on one or more specified nodes. Please verify your allocation and authorities.

• the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base). Please check with your sys admin to determine the correct location to use.

• compilation of the orted with dynamic libraries when static are required (e.g., on Cray). Please check your configure cmd line and consider using one of the contrib/platform definitions for your system type.

• an inability to create a connection back to mpirun due to a lack of common network interfaces and/or no route found between them. Please check network connectivity (including firewalls and network routing requirements).

我不知道该怎么办。你有什么想法我可以试试吗？在
