Modern processors can issue 4-8 integer/fp operations per cycle; RyuJIT supports it

int ArithmeticSeriesSumSimd(int n) { Vector4f vsums = new Vector4f(0, 0, 0, 0); Vector4f viter = new Vector4f(1, 2, 3, 4); Vector4f vstep = new Vector4f(4, 4, 4, 4); for (int i = 1; i <= n / 4; ++i) { vsums = vsums + viter; // ADDPS viter = viter + vstep; // ADDPS } return (int)(vsums.W + vsums.X + vsums.Y + vsums.Z);}
