[mvapich-discuss] can't set up mpd ring between two nodes (fwd)

[jetspeed]

Hi, huanwei:
	Thanks for your reply.
	1.  There is no other mpd running on the same node, I mpdallexit before I start mpd.
	2.	  there is .mpd.conf in the home directory, the two nodes share the $HOME by nfs. the content of the .mpd.conf is     secretword=1111

I want to use the InfiniBand , so I installed OFED 1.2.5,   I am not sure the InfiniBand is configured right, but the mpdcheck program between the two nodes works rightly.

I will check the README_MPICH2 you mentioned.  
Thanks again,
