Symmetric just means the system's CPUs are sharing same RAM and address lines and this way they can't be run absolutely independent but have to inform each other about their actual state. Threaded tasks can be divided to run on all CPUs, so this is one scenario from which an application on SMP gains it's boost. But there are a lot of applications using just one CPU at time and you will only gain improvement towards single CPU system if you run a further application at the same time which uses the other CPU. I do not know an answer to the original question, but on Windows[tm] NT based systems you can choose on which CPU an application should run.
