I have 32 available CPU cores and the affinity mask is:

00ff00ff

Can someone please help me understand which CPU cores the affinity is set to, using this number?

You can use bit mapping in binary (base 2) to select which cores you have enabled. 0 for off and 1 for on. Make groups of four blocks to with enough groups to represent all the cores you have. Each bit represents a core. Choose if each is on or off. Take the resulting 4-bit number and convert to hexadecimal (base 16). This will give you the hexadecimal code. For 00ff 00ff, it is 0000 0000 1111 1111 0000 0000 1111 1111. So, cores 0 - 7 and 16 -23 are off with 8 - 15 and 24 - 32 turned on. You can also use a calculator set to programming mode. Windows 10 default calculator has that function.
