Could someone please explain to me how I can make use of DCC via OpenCL ?

For example, if I have data stored in an OpenCL image, what flags do I need to set on the image

to make use of DCC ?

Thanks!

Can someone from AMD please respond? If you're not at liberty to tell me the details, please let me know.

I am trying to design my application to make use of DCC.

Kind Regards,

Aaron

Thanks.  I just have one unanswered question:  Does read only

mean images created with the flag CL_MEM_READ_ONLY, or does it mean images that are passed

into a kernel as read_only, but they could be written to in other kernels?

[tzachi_cohen · Accepted solution]

You will need to create the image object with CL_MEM_READ_ONLY.

Once again, DCC is a feature invented for graphics, its contribution to compute is marginal.

Great , thanks for the clarification.
