[mpich-discuss] mpdboot fails

[Darius Buntinas]

I'm not sure mpdboot supports that scenario.  I believe mpd must be in 
the same location on all machines.  You can try adding it to your path 
on each machine.

Otherwise, you can start the mpds by hand:

   On one node start mpd in the background:
     /path/to/mpd &
   Then find the port number it's using:
     /path/to/mpdtrace -l
   It should output something like:
     iMac.local_37896 (127.0.0.1)

   On the other nodes start mpd and tell it where to connect:
     /path/to/mpd -h iMac.local -p 37896 &

   Now, mpdtrace should show you all of the nodes.

Hope this helps.
