Complete Exercise 6 above to determine the parameters **a** and **m** (probably
) of Cray's ` ranf()`. Develop a vectorized version of ` ranf()`
by creating a vector of successive multiples of the coefficient **a**. For a
vector length of 64, for example, you will need a vector of (). Race your vectorized version of ` ranf()` vs. Cray's
` ranf()`, and see how close you can come to their execution time. To do
this, you will have to generate long vectors of random numbers, and use them
elsewhere in the code. Use ` second()` to obtain elapsed CPU time.
