----------------------------------------------
 Double precision has 15 digits of accuracy
 Assuming 8 bytes per DOUBLE PRECISION word
----------------------------------------------
 Array size = 32000000
 Offset = 0
 The total memory requirement is 732 MB
 You are running each test 10 times
 The *best* time for each test is used
 ----------------------------------------------------
 Your clock granularity/precision appears to be 900 microseconds
 The tests below will each take a time on the order
 of 168800 microseconds
    (= 188 clock ticks)
 Increase the size of the arrays if this shows that
 you are not getting at least 20 clock ticks per test.
 ----------------------------------------------------
 WARNING: The above is only a rough guideline.
 For best results, please be sure you know the
 precision of your system timer.
