    better control of the cache


      I think it would be good to add a mechanism to control better the memory caches.


      For instance, you could add a flag to the clCreateBuffer like CL_CACHED.

      clCreateBuffer ( .....,CL_MEM_READ|CL_CACHED  ... )


      Other option is to add a modifier keyword to the __global one:

      __kernel void MyKernel ( __global __cached int *w )


         const int data = w[get_global_id(0)];



      Sometimes I want the global memory cached but other times not.
