https://community.intel.com/t5/Intel-Integrated-Performance/matrix-subtraction-using-only-one-CPU/m-p/880664#M10149 Hi,<BR />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.<BR />Is there any way I can get both cores to run the subtraction? Will moving to an I7 processor improve this significantly?<BR /><BR />Thanks,<BR />Hagai.
