Please provide an example on how to correctly call a kernel multiple times so memory is not copied all the time

Can you elaborate this?

You can call clEnqueueNDRangeKernel multiple times, of course. (It will always do the same thing, unless you set different kernel arguments, or unless you read or write memory between the calls, but that should be clear).

Which memory are you referring to here?
