Do threads by default run on more than one core?

Question

In multi-core processors, and windows application runs many threads. do the threads by default run on more than one core ? I mean every thread might run on individual c

Answer 1

people seem to forget that a single core contains multiple ALU's and that although humans generate linear programming code, in reality multiple instructions can be done at the same time and that's not even considering the pipeline. Basically, cpu manufacturers need to figure out a way to make 1 pseudo core out of multiple cores not just the other way around.
