matrix subtraction using only one CPU

Hi,
I am subtracting two large matrix arrays (100300X300 matrices in each array) using ippmSub_mama_64f. I noticed that only one CPU is working while the subtraction takes place (I have a core 2 duo E6300). I am using IPP with static dispatching, andother functions utilize both cores.
Is there any way I can get both cores to run the subtraction? Will moving to an I7 processor improve this significantly?

Thanks,
Hagai.

Hi,
ippMX is intended for 3x3...6x6 matrixes only, maximum 20x20, but not for 300x300 - no optimization for such sizes at all.
