Usage
Use the
model-children
 option to:
  • Minimize overhead
  • Estimate offload speedup of a not-offloaded region head that has a
    Less or equally profitable than children offloads
     message
Example
  1. Run Survey Analysis.
  2. Run Trip Counts and FLOP analyses of the Characterization stage.
  3. Model only offloading of loop heads when modeling your application performance on a target device.
