    Does write_imagef use the texture cache?

    bubu

      Does write_imagef use the texture cache? Am I polluting the texture cache writing an independent texel per thread?

       

      I think read_imagef should use the texture cache but ... what happens with write_imagef? 

       

      And... are the write_imagef operations thread-atomic(auto-mem-fence) or can I enter a race condition if the CL threads write to multiple pixels?

       

      thx
