where you will find a very similar example.

So, for instance, if you wanted to pass a command argument
 -XmYm

where Y equals the amount of RAM in megabytes on the slot where the job is going to run, you could use $(..) in your submit file like:

 arguments = -Xm$(Memory)m

Now lets say you wanted the same thing, but you wanted to multiply by 0.9 (to account of overhead etc), you can insert the result of an arbitrary ClassAd _expression_ using $([..]) like so :

 arguments = -Xm$([Memory * 0.9])m

Or use conditionals like:

 arguments = -Xm$([ifthenelse(Memory > 10000, 10000, Memory * 0.9)])m

Hope the above helps
Todd
