Example: Point, RectDomain, Array

Pointɚ> lb = [1, 1];

Pointɚ> ub = [10, 20];

RectDomainɚ> R = [lb : ub : [2, 2]];

double [2d] A = new double[R]; // (no distributed arrays)

…

foreach (p in A.domain()) {

A[p] = B[2 * p];

}

Standard optimizations:

• strength reduction
• common subexpression elimination
• invariant code motion
• removing bounds checks from body
