[OS X TeX] OT: Mathematica and SL

I was wondering if Mathematica could use its multiple kernels (under my license I can use 4) in SL and ran  Mathematica's own Benchmark test.

With a single Mathematica kernel my machine (8-core Mac Pro 2.68 GHz, running a 64-bit kernel) scored 3.07 while using all 4 kernels it scored 10.00. If I recall correctly I ran the same test in Leopard, but though four Mathematica kernels were available only one had been used.

Actually there are 5 Mathematica kernels running, one is called master and the others local. Maybe the master kernel is distributing the tasks?

Let me add that while the test ran Time Machine was doing a backup.
