Hi Larne,

Look like your schedd is indeed running with Greg's v8.7.7 code patch here
  https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=6517
so it should be working for you...

Does your condor_config on your central manager include
  ALLOW_PSLOT_PREEMPTION = True
?

And the condor_config on all your execute nodes have a RANK expression 
that prefers your dedicated scheduler submit machine?  (e.g. like the 
example at http://tinyurl.com/yaolvshk ) ?

If the answer to both of the above questions is yes, then the next step 
is Greg will likely have more questions for you to get to the bottom of 
this...  After the above patch Greg observed parallel universe jobs 
working here at UW with partitionable slots, so imagine he will need to 
figure out what is different at Syracuse...

Thanks
Todd
