[求助] ms 跨节点并行出现问题

安装了ms以后可以单节点上并行，我们服务器是8个节点，每个节点8个核，也就是说我使用少于8个核并行没有问题，但是超过8个核的话就有这样的提示


mpirun: hostname: localhost, ip returned: 127.0.0.1
mpirun: hostname: cu02, ip returned: 192.168.0.2
mpirun: hostname: cu03, ip returned: 192.168.0.3
mpirun: Can't talk to a remote host with IP 127.0.0.1
mpirun: Change hostname or check IP configuration

然后我执行 ssh  127.0.0.1(localhost) 也出现这样的提示
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!    @

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
e7:7b:ed:23:a6:c5:e1:92:77:8c:ec:8e:80:69:3b:7f.
Please contact your system administrator.
Add correct host key in /home/huhaixiang/.ssh/known_hosts to get rid of this message.
Offending key in /home/huhaixiang/.ssh/known_hosts:6
RSA host key for 127.0.0.1 has changed and you have requested strict checking.
Host key verification failed.

不知道为什么hpmpi 会把127.0.0.1当做主节点的ip，它的ip 应该是 192.168.0.1。
