STREAM results

Here are the benchmark results for a machine I am using.

The benchmark code is unmodified, and compiled with

gcc -O stream.c -o stream

gcc (GCC) 4.4.6 20110731 (Red Hat 4.4.6-3)

on
Linux blahblah 2.6.32-220.4.2.el6.x86_64 #1 SMP Tue Feb 14 04:00:16 GMT 201=
2 x86_64 x86_64 x86_64 GNU/Linux

a virtual machine configured with 96GB of RAM and 1 CPU / 6 "threads"

Hosted on VMWare ESX 5
Running on a Supermicro server, motherboard model MBD-X8DAH+-F-O
2x Xeon E5645 @ 2.40GHz with 144GB of RAM

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.

Printing one line per active thread....
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 3680 microseconds.
   (= 3680 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.
