I don't know what you mean by 'grid'.  I am also not really sure what
you want to happen.  How many 'slots' (I assume you mean 'cores') do the
jobs require?  Do A and B each submit one 12-core job or 12 single-core
jobs.  If the former, then either A's job or B's job will run first; if
the latter, then it just depends on exactly when the jobs are submitted.

You could also set

  PriorityWeightFairshare=0

to remove even the effect of the CPU-usage over the day.

Cheers,

Loris
