 Double precision appears to have 16 digits of accuracy
 Assuming 8 bytes per DOUBLE PRECISION word

 Array size =   41234567
 Offset     =          0
 The total memory requirement is  943 MB
 You are running each test  10 times
 The *best* time for each test is used
 ----------------------------------------------------
 Your clock granularity/precision appears to be  10000 microseconds
 The tests below will each take a time on the order 
 of       320000  microseconds
    (=           32  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.
