 * `sum-divisors`: Prints the positive integer divisors of the input integer, followed by the sum of the divisors.
 * `sum-sq-diff`: Output the difference between the sum of the squares of the first *n* natural numbers and the square of their sum.
 * `up-arrow`: Computes [Knuth's up arrow][uparrow] notation, with the first argument being the number, the second argument being the number of Knuth's up arrows, and the third argument being the number of repeats.
+* `simd`: Multiplies a constant to each element of a large array. Tests the performance of vectorization optimizations.
 
 Credit for several of these benchmarks goes to Alexa VanHattum and Gregory Yauney, who implemented them for their [global value numbering project][gvnblog].
