Radiance Benchmark Test

BENCHMARK RETIRED Due to changes made to the Radiance HEAD release dated 2005-05-25 (and all versions thereafter) and its different handling of the ambient cache for scenes with significant specular components, the bench2 benchmark scene must be retired. A new benchmark scene and a new table of results is currently being created and will appear here shortly. All results tabulated below are still internally self-consistent (see note 3). The work scaling between this scene and bench4 is roughly 1:23.

Go to the new benchmark page.

This section contains instructions for running a sample Radiance test scene and the results from many different computers. The test is not intended to represent all that Radiance can do, nor is it neccessarily representative of the way Radiance is commonly used. It is simply a good scene with reasonable complexity, some procedural texture use, and some interreflection calculation.

The scene within, and the files obtainable below, are the original work of Paul Bourke, who maintains a Benchmarks for Radiance page in Australia with different scenes. Please take a moment to visit it if you can.

Instructions

  1. You must download and build Radiance, or have the Radiance distribution on the machine you wish to benchmark. Download the Radiance distribution from the "download Radiance" page of the Radiance Online site.
  2. Download bench2.tar.gz and use gunzip and tar -xf to create the bench2 directory.
  3. In the doit file are listed several commands. You will need to run each of the commands listed in the order they are listed. Use whatever timing device you have available to determine the CPU time required (not neccessarily the real, elapsed time). On an SGI and other Unixes this can be accomplished by prefacing each command with the time command, like: 
    time oconv scene.rad > scene.oct
    Of primary importance is the rpict command, but for the sake of possible interest, try to record times for each of the three commands.
  4. Using whatever means neccessary, compile the information for the other fields listed in the table below. A complete entry is desired, but not required. You can get the version number from the command rpict -version, OS name from uname -a, compiler version usually from [compiler] --version, processor info from cat /proc/cpuinfo, and RAM from running top and reading the amount available.
  5. E-mail the information to me, mstockATumich.edu, and I will add it to the table below.
  6. Choose the guilty pleasure of your choice and indulge.

Results

Note 1: this information is not meant to serve as an exact speed comparison among machines, as unmentioned hardware configurations can have an impact on the speeds reported.

Note 2: rows ordered by rpict time

Note 3: The upgrade to Radiance 3.5 included changes to oconv's default behavior, which explains the differences between oconv timings; but more importantly, Radiance 3.6 includes changes to rpict's default parameter settings. The link to the scene data is for the new version of the benchmark tests. It uses consistent parameters and should be used for new benchmark tests
