Workload & symmetry rules

Workload

For each of 200×200 pixels: iterate the Mandelbrot recurrence z = z² + c up to 80 times, count the iteration at which |z| > 2. Output the sum of iteration counts so canonical hashing doesn't depend on FP equality.

Symmetry rules

  • Pure float64 scalar arithmetic (no complex type, no numpy, no math.cmath).
  • Inner loop manually unrolled per the README's reference shape; no language-specific shortcuts.

Why this benchmark exists

The one shape of work missing from the rest of the suite: a tight float64 inner loop. This is where pipit's typed float register bank pays its biggest dividend.
