问题
Is there a way to get the compute unit ID a work group is running on during runtime? I know that CUDA has some assembly code to do this.
回答1:
No, there isn't a way to get the compute unit's ID. Your code should use the work group ID instead. What are you trying to achieve?
I am a little surprised that CUDA supports this, please tell me which assembly code instruction does this.
