Fermi Warp Sheduling

Hello, I write GPGPU reviews for my master’s diploma. And I have questions about dual warp sheduler on Fermi.


Why double-precision instructions can’t be dual-issued with another instructions, such as transcendent functions, or load/store ones?

Are double-precision instructions executed connecting two cores (like on AMD GPUs)?

If possible, please tell about sm2.0 and sm2.1 respectively.

Thanks, and sorry for my poor english :unsure:
