Is the process of mapping an application onto a heterogeneous collection of resources mostly a guess and check process that depends on the specific application? Or is there an accepted methodology that most people use when mapping to the resources?


@emt, It becomes a matter of guess and check in some cases where the underlying hardware is not completely open (Eg: Adreno GPUs). However, an informed estimate can be drawn when you know the details of the underlying architecture (Clock freq, IPC, Vector Width, etc).
