 The total memory requirement is 1532 MB
 You are running each test 5 times
 The *best* time for each test is used
 ----------------------------------------------------
 Your clock granularity appears to be less than one microsecond
 Your clock granularity/precision appears to be 1 microseconds
 The tests below will each take a time on the order
 of 67861 microseconds
    (= 67861 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.
