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?

 

Thanks

Sajjad
