Can u explain this statement "check whether the scan qualifier can
be executable on GPU device"

What are the scan qualifiers?

How to determine whether they are device executable or not?

The cost estimates are entirely based on number of rows and type of scan.
Then it will be same for both CPU and GPU. How the decision can be made for
cheaper one comparing CPU and GPU estimates?
