How does that help?

So if an instruction
does not complete in its cycle, they switch to a different set of
threads;

That will need to do its own memory accesses. But the memory interface is
still busy trying to complete the access for the previous thread.

Also note: a single instruction causes 32-128 threads to make 1 step of
forward progress.

How many memory accesses does it take to complete that one step?
