clCreateBuffer & clCreateSubBuffer

Hi,

Referring to OpenCL specs for clCreateBuffer

 

"OpenCL implementations are allowed to cache the buffer

 

contents pointed to by

 

 

host_ptr in device memory. This

cached copy can be used when kernels are executed on a

device."

 

Q1. What is the cache size used by AMD GPU

A) ATI RV770 ?

B) new 6990 ?

 

Q2. What is the minimum and maximum for region of clCreateSubBuffer function ?

Q3. Are there any limits / recommendations to number of regions in a buffer - due to cache feature for example ?

Q4. Can one release a created sub-buffer ?
