Merging Arrays Example

Merging Arrays Example. /* Before: 2 sequential arrays */ int val[SIZE]; int key[SIZE]; /* After: 1 array of stuctures */ struct merge { int val; int key; }; struct merge merged_array[SIZE]; Reducing conflicts between val & key; improve spatial locality. Loop Interchange Example.
