its a binary system, so keep in mind that;

Core 0 (1st core) = binary 1
Core 1 (2nd core) = binary 2
Core 2 (3rd core) = binary 4
Core 3 (4th core) = binary 8
Core 4 (5th core) = binary 16
Core 5 (6th core) = binary 32


so basically you have a software dipswitch setting, so if you wanted to run your sim on all cores available, you would add up all the binary associated with those cores.

So to have your ProcessAffinityMask setting to use all four cores, you would addup the binary for cores 0 through 3, which is 1 + 2 + 4 + 8 equaling 15.

For all six cores (0 through 5) you would have 1 + 2 + 4 + 8 + 16 + 32 = 63.

Some say a four core processor is best when Core 0 is left for the Operating System and run the sim on Cores 1, 2 and 3 only, this would involve adding binary 2 + 4 + 8 eaqualing 14.

If the user wanted to run the sim on core 3 (4th Core) only, the PAM setting would be 8

Having said all that, it appears that the ProcessAffinityMask line has been removed from the latest Config file, which is fine because (at least on my machine and according to some others) the sim runs much better without the setting because the sim is utilising cores much better than it did when the sim was frst released.
