[MPICH] MPDBOOT Problems

[Rajeev Thakur]

You need to use the mpdcheck utility to debug the problem as described in
the installation guide. The networking environment is probably not set up
right.

Hi all, 

I have installed MPICH2 in a shared folder outside home dir.

And i shared this folder with other 6 computers in a cluster.

Well, when i try to run mpdboot it doesnt work for more than 2 PCS.

When i try mpdboot -n 2 -f <hosts file> it performs ok, however when i try
with 3 PCS or more i doesnt works and record an error message like this
following message :

mpdboot_computer1 (handle_mpd_output 374): failed to ping mpd on computer1;
recvd output={}

It is strange because with 2 PCS, this one computer1 works, and now with 3
it doesnt work anymore. 

Furthermore, i touch and set permission to .mpd.conf files in every node of
the cluster, and i set the secretwork too..

What is going on with MPDBOOT?

Thanks in Advance,
