Thanks for pointing that out Reuti, I was running into the same issues:

Changing this in the starter script
`hostname --short`

And missing this line in my mpd job script:
export MPD_CON_EXT="sge_$JOB_ID.$SGE_TASK_ID"

Thanks and enjoy the rest of your vacation :-)

Bingo!!  that was it.  I was wondering how I missed it and my only excuse is 
that it's mentioned in the text only one or two times and my browser didn't 
wrap the text so that the reference was offscreen as I was scrolling thru it 
the 2st few times.

I have no idea whether this will be useful to others, but I've documented our  
set up on a mixed (public/private net) cluster for our users and have just 
updated it to address this problem:
<http://moo.nac.uci.edu/~hjm/BDUC_USER_HOWTO.html#_parallel_jobs_with_mpich2>


I also have some SGE debugging for that cluster on our Trac:

Thanks again,

harry

It is better to be roughly right than precisely wrong.
