Since I am bored and can’t go out and ride my bike in the rain I used XCode to write a C program on my iMac to multiply two 4086 x 4086 matrices of 64 bit floating point numbers. I used a complex, robust random number generating algorithm to fill the arrays. This takes 17 seconds. Then I multiplied the two arrays to fill a third array. This takes 0.102632 seconds. You have to wonder how the authors could have gotten such crappy results even using crappy languages.
