Extremity nodes and measure
Bottleneck resources: hardware ? area, Software ? time
Hardware extremity nodes and software extremity nodes
Ei = extremity measure that is used to modify the threshold to which GC is compared when selecting the mapping objective. ( local phase delta for an extremity node i)
Procedure: Compute_Extremity_Measure Ei for such nodes
Input: tsi, ahi, ?i? N, ?, ? percentiles
Output: Ei ,?i? N, -0.5 ? Ei ? 0.5
S1. Compute the histograms of all the nodes with respect to their software execution time and hardware areas.
