Try running the mpdcheck troubleshooting utility as described in the
installer's guide.

Hi 
i'm new to MPICH2 and i just installed mpich2 , but i can't make it run on a
set of machines.

i run mpich2 on 2 nodes  , hostnames are hewonty and vm1.
Here are some info 

[hewonty at hewonty ~]$ cat mpd.hosts
hewonty
vm1

[hewonty at hewonty ~]$ cat /etc/hosts
127.0.0.1       localhost.localdomain   localhost
192.168.2.2     hewonty.homelinux.org   hewonty.vmnet1.org      hewonty
192.168.2.3     vm1.hewonty.homelinux.org       vm1
192.168.2.2     svn_server

[hewonty at hewonty ~]$ mpdboot -n 2 -f mpd.hosts
mpdboot_hewonty (handle_mpd_output 359): failed to ping mpd on hewonty;
recvd output={}

i can ssh to hewonty or vm1.

I tried to run mannually by mpd and here are what i got

[hewonty at vm1 ~]$ mpd &
[1] 2056
[hewonty at vm1 ~]$ mpdtrace -l
vm1_32772 (192.168.2.3)


[hewonty at hewonty ~]$ mpd -h vm1 -p 32772
hewonty_32846: mpd_uncaught_except_tb handling:

    /usr/local/mpich2/bin/mpd  231  run
        rhsHandler=self.handle_rhs_input)
    /usr/local/mpich2/bin/mpd  1344  ?
        mpd.run()

Thanks in advance.
