Hi developers,

CP2K may need extra cost in the first launch kernel when using GPU. It 
needs to load related code into GPU memory. The cost should depends on the 
size of kernel object code.
This behavior will not need to do again in the process life cycle if GPU 
memory is enough.

Is there any way to by pass the first launch time when we are doing the 
benchmark testing? In this way, we can observe the real cost of total 
kernel cost.
For an example, running a benchmark test with specified iterations in one 
CP2K process lifecycle and having a result of average without the first
