Copy between buffers
I would like to have a method for copying data from one buffer to another. I would also like to be able to specify where this copy should take place in the dependency graph.
starpu_data_copy(src_buffer, dest_buffer, offset_src, offset_dest, size, dependencies)
With this I could implement clEnqueueCopyBuffer, clEnqueueReadBuffer and clEnqueueWriteBuffer efficiently.
