Testing the octave system, octave is a free alternative to MATLAB. This is a quick running single-threaded benchmark.
Topdown profile is sparse because it runs quickly. Frontend stalls are the highest points.
AMD metrics show a moderate amount of floating point and branches. Frontend stalls are highest and L2 access is medium.
