SMP should be using 4 cores... you should have 4 instances of the core running. Check task manager you should have fahcorea1.exe (i think thats the right name) running 4 times if it is only using 1 core then it is not working correctly.

What system are you running? Oh and the GPU client will load a CPU core as well so it may be that the SMP client is not running at all and what you are seeing is the GPU client.

If you want ot run multiple clients at the same time you will need to add a few tags to the executables -l (local will make it store its files in its own space rather than a central location) and then you will need to in the configuration options set the machine ID for the different clients to different values for example 0 and 1.
