VIPS SMP benchmark
This benchmark is useful for testing the VIPS SMP system, for comparing host systems SMP implementations, and for testing for performance regressions or improvements between versions of VIPS. We have a separate set of benchmarks comparing VIPS to other image processing systems on the Speed and Memory Use page.
VIPS (from version 7.11.12) includes a benchmark for testing SMP systems. This benchmark is adapted from the system used to generate images for The National Gallery's Print on demand service. We have a couple of presentations about the background to POD available as well.
Images from a 10k by 10k studio digital camera are colour processed, resized, cropped and sharpened. You can see the exact sequence of operations the benchmark performs in the source code. This thing was originally processing images off a remote server over a 100 MBit network. No attempt was made to make it quick (there was no point); you could make im_benchmark a lot faster very easily if that was your aim.
There's a small shell script in vips-7.x/benchmark which runs im_benchmark on a test image with varying numbers of threads and reports the times. After building and installing VIPS you can type:
cd vips-7.x cd benchmark ./benchmarkn.sh
And see results for your system.

Time is real time (wall clock time) in seconds, Speedup is (real-1-cpu-time / real-max-cpu-time).
Results in detail
The results we've collected. Please paste more here.
For each one we've noted uname -a, gcc --version and vips --version.
We configured VIPS with no extra optimisation options, ie. everything just has the default -O2.

SGI Origin2000 supercomputer
VIPS 7.11.20 has also been run on a 64-CPU supercomputer (an SGI Origin2000) at Princeton. The results are:
| CPUs | Run time (s) | Speed up |
|---|---|---|
| 1 | 651.85 | 1 |
| 2 | 335.9 | 1.94 |
| 4 | 170.07 | 3.83 |
| 8 | 86.06 | 7.57 |
| 16 | 44.56 | 14.63 |
| 32 | 24.06 | 27.09 |
| 64 | 16.54 | 39.41 |
So about a 40 x speedup for 64 CPUs.
If you graph these numbers you get:
So it's pretty much linear up to about 30 CPUs (with a 27x speedup). The image being processed is 1.3GB so perhaps we are starting to see IO bandwidth limits.
