I have just taken a quick look at the code, and I think that in 
refocusing_opencl_codelet(), the calls to STARPU_MATRIX_GET_PTR() should 
be replaced by calls to STARPU_MATRIX_GET_DEV_HANDLE().

I think that currently, clEnqueueWriteImage() is given an invalid "ptr" 
argument, which explains this issue.
