Dear Doug,
you are right.

num.proc is used to specify the maximum number of proc you want to 
expose with opal, then you have to specify the number of processors you 
actually wanna use when you launch a job.

So for the command line client it is already supported, but not for the 
web interface.

What version are you using? I can patch Opal web interface to support 
that feature and make a new release 1.9.5 in a short time frame (less 
than a week). This was on my TODO list for a long time.

Sincerely,
Luca
