GA-7N400 Pro motherboard (nVidia nForce2 chipset)
AMD Athlon 2500+ (Barton core, 1.833 GHz)
Dual-channel PC3500 memory --- memory was running at
either 333 or 400 -- the BIOS is not very clear on this...
I selected "Turbo" mode, and it did not tell me the
memory frequency.... FSB was definitely at 167/333.
More overclocking experiments later.....
OS is RedHat9
Compiled with gcc (3.2.2) -O2 -funroll-loops

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

Array size = 2000000
Offset = 0
The total memory requirement is 45 MB
You are running each test 10 times
--
The *best* time for each test is used
*EXCLUDING* the first and last iterations

Your clock granularity appears to be less than one microsecond
Your clock granularity/precision appears to be 1 microseconds
