Do we have to keep the test script in Load generator machines

Hello

I know this is a vary basic question ( may be a dumb question), but am trying to collect information here.

Do we need to keep the performance test scripts and test data like csv files etc in the load generator machines ?

I know Neoload controller is the one who triggers the test, and we can have as many LG running in separate machines, and we make a connection between Controller and LG

In this scenario I guess, the perf test scripts and data file would need to be present only in the controller machine
or am I wrong, do we need to keep them in LG machine as well
Please let me know

Thanks
