[mpich-discuss] mpdboot fails

[Rajeev Thakur]

-mpd just specifies the path for mpd on remote hosts (the same path for all
remote hosts). If it still doesn't work, there may be some problem with the
networking configuration on the two machines. To debug the problem, you can
use the mpdcheck utility as described in the installation guide (all steps).
