The tests are of two types:
Note that these tests will not be listed as specifically integer or floating-point tests; rather, they will be grouped is image processing tests. This is because I have no way of knowing exactly what each test is doing in terms of int vs. fp calculations - this is especially true of the combinational scripts.
The results tables will include the disk type for each system when a TYPE A test is being described. For multi-CPU systems, only one CPU is used for these tests.
Results notes: the advantages of having a more modern system are clear: an Origin200 with a 180MHz R10K often beats an Indigo2 with a 195MHz R10K, ie. the Origin design gets more out of the chip technology. The benefits for rendering (eg. BMRT, PovRay, etc.) should be even greater (I hope to do some rendering benchmarks later in the year). However, the differences become less if a task is mostly integer processing, eg. the Origin is half way between I2 R10K/175 and R10K/195 for the Circuit test below, probably because that test is mostly integer processing, while the Lava test is likely a mix of int and fp.
Imaging Test 1 is TYPE A, as explained above.
The data file to be processed is the 48MB image file that comes with the O2 'roam' demonstration program, called 'sanFran4k.tif' (a large aerial photograph of San Fransisco, USA), but for the purposes of the test I convert the image to RGB format using imgworks. The test file is thus a 4096 by 4096 RGB image of size 50,332,160 bytes (ignoring the image file header, exactly 48MB).
Since TYPE A tests always involve big image files, it's important that a test system has a large amount of RAM. I always use at least 256MB RAM (128MB is definitely cutting it too close when working with 50MB+ images). Note this means that even an old Indigo could run such tests since Indigo can have up to 384MB RAM. A lot of RAM is required because of GIMP's UNDO buffers.
How to run the test: first download and install GIMP V1.0.4 if you don't already have it (NB: this test is using V1.0.4; the latest version - which was V1.2.0 the last time I checked - can be downloaded from the main GIMP site). You will also need to install at least GTK V1.0.6 in order to install this version of GIMP. Next, convert the sanFran4k.tif image to RGB using imgworks (get the file from the O2 demo CD, or borrowed from someone who has the demo installed). Then, load the image into GIMP; use the right mouse button to bring up the main menu and select 'Filters', followed by 'Distorts', and finally 'Ripple'. Get ready with your stop watch: click on OK and start the timing. When the operation has completely finished (the new image is fully redrawn on the screen, ie. one is able to bring up the right-button menu again), stop the timing. Be warned: this operation could take a very long time on a system such as a low-end Indy (perhaps 15 to 20 minutes), so be patient!
