Hi All ,

I have a Question :

Can we set priority of threads within a block?
or

Can any technique to run threads in a block in their relative order?

No.

No.

Threads in a warp run concurrently, AKA at the same time. You can have the threads diverge, and serialize execution, in which case, you could control the relative order in a warp only. Of course, doing that will end you with a 32x performance drop FYI.
