SW Weenies: Ready for CMT?

tbray writes "The hardware guys are getting ready to toss this big hairy package over the wall: CMT (Chip Multi Threading) and TLP (Thread Level Parallelism). Think about a chip that isn't that fast but runs 32 threads in hardware. This year, more threads next year. How do you make your code run fast? Anyhow, I was just at a high-level Sun meeting about this stuff, and we don't know the answers, but I pulled together some of the questions."

How is this different from having multiple cores?

...and isn't this the challenge being addressed by DragonFly BSD?

Software people use threads already, as long as the VM and OS are up to the task. I don't see why it should matter if some of the threads are implemented in hardware.
