C-Ray is a simple raytracing benchmark written by John Tsiombikas; in John's words, C-Ray is:

  "...an extremely small program I did one day to figure out how would the
  simplest raytracer program look like in the least amount of code lines."

The default test scene involves only a small amount of data, such that on most systems the CPU does not have to access main RAM to run the test. Indeed, some systems could run much or even all of the test in L1 cache. I asked John if this meant more complex real-world situations might behave quite differently, eg. scenes that refer to external texture data or large amounts of other geometry and so on. He said yes, and continued:

  "This thing only measures 'floating point CPU performance' and
  nothing more, and it's good that nothing else affects the results.

  A real rendering program/scene would be still CPU-limited meaning that
  by far the major part of the time spent would be CPU time in the fpu,
  but it would have more overhead for disk I/O, shader parsing, more
  strain for the memory bandwidth, and various other things.

  So it's a good approximation being a renderer itself, but it's
  definitely not representative."
Thus, C-Ray is an interesting fp test, but be careful of extrapolating the results to other situations. However, if another task behaves in a similar manner, then the results here could be a useful guide to how various systems compare. So, remember: this is a CPU core test; it doesn't test main RAM speed and it doesn't test I/O, though more complex settings can at least force the dataset to move out of cache to some degree. C-ray operates by allocating a single scanline in the image to a separate thread, which is why it scales so well; this means there's no point defining the number of render threads to be greater than the pixel height of the image.

Two scene files are used, a simple one called "scene" and a much more complex file called "sphfract" which takes a lot longer to render (see above for screen shot thumbnails, click on them for larger versions). Results are shown in milliseconds.

There are several tables on this page (widen your browser window to see them better). The old main table (Test 1) has been moved near the bottom of the page as it was a very short & simple test which isn't all that useful even on old SGIs, ie. it completes far too fast. I have thus moved Test 3 ("sphfract" at 1024x768 with 8x oversampling) to the top of the page, and have started a new table (Test 5, no entries yet) for a much more complex scenario, but the downloadable archive has not yet beenupdated to reflect this.

Next on the page is Test 2, sphfract at default 800x600 with no oversampling. After that is Test 4, "scene" at 7500x3500 with no oversampling (I can't remember why I chose this resolution, possibly a format option I saw within Flame or something). Then comes Test 5, sphfract at 3840x2160 (ie. "4K") with 8x oversampling, though these details might change as I try to establish what settings AMD used for their Rome presentation, eg. they may have used deeper oversampling.

Second-last there is the original Test 1, 'scene' at default 800x600 with no oversampling. This is a very short test, which means the overhead from running it on a large multi-CPU system can overwhelm any potential speed gains, so be careful how you interpret the results.

The last table is aimed solely at SGI users and contains just the SGI results from Test 1.

If you would like to run the tests yourself, then download the archive and consult the included README on how to run the tests. John wrote two versions of the program: c-ray-f for single-CPU/single-core systems, and c-ray-mt for multi-CPU/multi-core systems. If you have a single-CPU or single-core system, then c-ray-f is usually faster, but sometimes running c-ray-mt with 1 thread can be slightly quicker. Send any results to me at my Yahoo address, not to John.

WARNING: I have no way of verifying most of the submitted results. If you think any of the results look suspicious or fake, please contact me.

NOTES

One obvious point about the multi-CPU SGI results: for the shorter default 'scene' test, the degree of communications overhead is considerable, making the results less than ideal compared to the speed obtained on a system with just one CPU of the same type, eg. coms overhead of the 32-CPU R14K/600 O3400 is 25% compared to the ideal speed based on a single R14K/600 in Octane2 or Fuel. By contrast, for the more complex and longer tests, the scaling is much better with a lot less of a coms overhead, eg. the 32-CPU O3400 is only 2.8% slower than ideal for the high-res 'scene' test. Given the stated simplicity of the default 'scene' test, this does prove John's original comment that a more complex real-world render test would be a better basis for making judgements about one system vs. another, so perhaps the later tables are more useful in that respect. However, I'll leave the table ordering as it is for the moment.

Details of Dr. Dave's overclocked Octane2:

"... it's a 400 overcklocked to 481.25 MHz, on a SysAD of 87.5 Mhz, with cache clocked at 240.625 Mhz (cache divisor of 2, not 1.5). For comparison's sake, a 400 is usually either on a SysAD of 100 or 114.285 MHz, with the cache clocked at 267 Mhz (cache divisor 1.5) - though I've not seen any performance issues with the lower SysAD in the benchmarking I've done. It probably doesn't start being an issue until you've got a fast dual-processor setup. 485-ish is about as fast as you can go on a native 400, and even then it's luck of the draw.

Details of Simon M. Jones' Altix 350/450 systems:

Altix 450 with a single compute/memory blade, average results submitted from five
runs, using the "RUN.full" script with no other user jobs running on the system.
Also run on an Altix 350 with a single compute/memory blade, same 5-run average.

Binaries were built with GCC 4.3.4 and "-O3" optimization, no funny business.

At some point I'll try it with all four blades / 16 cores installed, and then try the Intel compiler.

System details:

Altix A450, single compute/memory blade installed.
2 x Itanium2 9040 "Montecito" @ 1.6GHz, 533MHz FSB, dual-core CPUs (4 cores total per blade),
20GB RAM, 1 x Fujitsu  MAX3073RC (73GB, SAS, 15k).

Altix 350, single compute/memory blade installed.
2 x Itanium2 1300 "Madison" @ 1.3GHz CPUs, 400MHz FSB,
6GB RAM, 1 x Fujitsu MAP3735NC (73GB, SCSI).

For both systems:

SuSE Linux Enterprise Server 11 SP 1
SGI Foundation Software 2 SP1
SGI ProPack 7 SP1
gcc (SUSE Linux) 4.3.4 [gcc-4_3-branch revision 152973]
