I have an HD 7700 GPU, on windows 7.


Here is how I am currently managing my memory:


1) I allocate a host buffer using new[] operator, aligned to page size (4096 bytes)

2) I allocate a device buffer via clCreateBuffer, using the CL_MEM_READ_ONLY flag

3) I transfer from host to device using clEnqueueWriteBuffer(...), with blocking set to CL_FALSE.


I have found this method to be pretty fast. Can I do better?
