[stream] Stream on SMP AMD Opteron

Thanks for the Stream bench. These results are obtained on a RackSaver
rs1100, which is a 2-CPU AMD Opteron 244 running Linux 2.4.23, with gcc
3.3. The machine has 8GB main memory, 4GB local to each CPU, so it is a
slight NUMA. Compiler flags were -m64 -O.

-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 100000000, Offset = 0
Total memory required = -1807.2 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 9999 microseconds.
Each test below will take on the order of 689999 microseconds.
   (= 69 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.
