Re: [Starpu-devel] Error - No worker may execute this task

One odd thing is this:

> cl_mem d_tex = clCreateImage2D(context, CL_MEM_READ_ONLY, &format, width, 
> height, 0 ,(void *) d_src, &err);

as examplified in the documentation, what STARPU_MATRIX_GET_PTR()
returns is a cl_mem, i.e. a device pointer, not a host pointer. Why do
you want to create an image and copy data in it actually? StarPU already
handles all CPU/GPU transfers for you, you just need to use the d_src
and d_dst buffers.
