Is software "x" multi-threaded?

[messiahnet]

I understand that major performance increases can be exhibited when dual/multi-core CPUs are paired with "multi-threaded" software. How can I know whether a certain software is multi-threaded or not? Is there a tool to test for the attribute or is there a decent up-to-date list of these applications?

Most software isnt multi-threaded, and those that are only offload a small task to the other core, so it still doesnt effectively take advantage of multiple cores. However almost all the new software coming out will start to take advantage of multiple cores since its becoming the norm.
