Computer:
Nekotech MachII with 300MHz Alpha 21064A CPU, 2MB L2 cache. DEC OSF/1 v3.2a.
Compiler:
cc -O4
Output:
-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 2000000, Offset = 0
Total memory required = 45.8 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 16666 microseconds.
Each test below will take on the order of 316666 microseconds.
(= 19 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.
