System configuration: Intel PentiumII processor @ 4.5x100MHz = 450 MHz,

512 KB L2, Asus P2B motherboard with Intel 440BX chipset, 256 MB PC-100

----------------------------------------------

Double precision appears to have 16 digits of accuracy

Assuming 8 bytes per DOUBLE PRECISION word

----------------------------------------------

Array size = 5566778

Offset = 0

The total memory requirement is 127 MB

You are running each test 3 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 240000 microseconds

(= 24 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.
