    data transfer between cpu and device


      Hello forum,


      I guess There are two ways to transfer data between cpu and gpu in OpenCL.


      1. The Natural way - clEnqueueWriteBuffer() / clEnqueueReadBuffer()


      2. Map/Unmap way - clEnqueueMapBuffer()


      Which one is the better option for data transfer when large amount of data will be  involved?
