[mpich-discuss] [HELP] Cannot start mpd

[Dave Goodell]

It's hard to say what the problem is, although it sounds like a  
networking configuration problem.  Did you try the troubleshooting  
steps listed in Appendix A of the Installer's Guide?  In particular,  
did you try the steps that use the "mpdcheck" utility?
