Hello.  The configuration of Condor has been change to implement 
priority and suspension of different jobs.  There will be 4 different 
class of jobs: High, Med, Low and MC.

High -----  bramreco ltr jobs only  (default for bramreco)
Med -----  bramreco gtr jobs (and probably dst jobs)
Low -----  standard user jobs  (default for all user).
MC  -----  Monte Carlo jobs   (Please use this class for your simulation 
jobs)

You select these options with "+Priority = " in your job description file.

Now, what these different classes do is described below.
Any higher level jobs will suspend any lower level jobs if necessary.  
For example, if you(standard user) submit 100 jobs in rcrs, they will be 
using all CPUs.  If 10 ltr jobs by bramreco are submitted later, 10 of 
your jobs will be suspended immediately until bramreco's ltr jobs are 
completed since your jobs will be "Low" whereas bramreco ltr jobs are 
"High".  It is important that you use the right class for your jobs.  
(Use MC for your Monte Carlo jobs)


If you use my condor_wrapper.rb (in ~hito/bin/condor_wrapper.rb), I 
already  included this option. as  --jobType = MC (or Low)
