Can some kind soul post a mips3 binary of c-ray so I can benchmark my Indigo2? I notice Ian is missing a result from a 200MHz R4400, and although I could use GCC, I think I'd prefer a MIPSPro version.

Pretty please? With sugar on top? :)

IP22, IP26 or IP28?

Presumably IP22 since he mentions R4K/200. :)

Awesome! Thank you! Your binary is currently murdering my Indigo2 as we speak. I should have the results of all the tests in a few hours. ;)

EDIT: And it's done! My Indigo2 has the distinction of being the slowest system reported to Ian for tests 2, 3, and 4, and almost took test 1 except for an Indy and jan-jaap's funkadelic R3000 Indigo! :mrgreen:

Code: Select all

cat scene | ./c-ray-mt -t 1 > foo.ppm
Rendering took: 19 seconds (19137 milliseconds)

cat sphfract | ./c-ray-mt -t 1 > foo.ppm
Rendering took: 518 seconds (518746 milliseconds)

cat sphfract | ./c-ray-mt -t 1 -s 1024x768 -r 8 > foo.ppm
Rendering took: 6748 seconds (6748199 milliseconds)

cat scene | ./c-ray-mt -t 1 -s 7500x3500 > foo.ppm
Rendering took: 1132 seconds (1132306 milliseconds)

Ok, now you've really gone and done it - I'm going to have to run the tests on an R4000PC/100 Indigo2. ;D

Hmm, and I also now have a 12MHz Personal IRIS, that should be a laugh...

^^^ hahaha! I'll get you a Blender benchmark once I figure out why it's dumping core. I think it's because I only have 128MB of RAM. I'll have to upgrade.

:D

You wouldn't believe how slow an R4000PC/100 is (ie. no L2 cache). If it was any slower it'd go backwards... though it'd still be
better than a PC of the day, hehe.

Got a new Linux development system in the other day. It's crammed into a really small case:
thermaltake_element_q.jpg
thermaltake_element_q.jpg (17.38 KiB) Viewed 404 times

But's it's full of the latest goodies:

Code: Select all

Core i5 2400S CPU ("SandyBridge", 2.5GHz QuadCore, no HT, with graphics)
Gigabyte GA-H67N-USB3-B3 board
8 GB RAM
OCZ-Vertex2 SSD

It runs OpenSUSE 11.4 (x86_64), out of the box, no issues worth mentioning.

Time to warm up the compiler (Intel ICC 12.0.3) 8-)

Code: Select all

$ cat scene | ./c-ray-mt -t 32 -s 800x600 > foo.ppm
c-ray-mt v1.1
Rendering took: 0 seconds (67 milliseconds)

$ cat sphract | ./c-ray-mt -t 32 -s 800x600 > foo.ppm
c-ray-mt v1.1
Rendering took: 1 seconds (1428 milliseconds)

Larger #threads doesn't seem to affect performance (64: 1430ms, 256: 1428ms).

Seems like GCC (4.5.1 as shipped with SUSE) doesn't fully exploit the SandyBridge CPUs yet:

Code: Select all

$ cat scene | ./c-ray-mt -t 32 -s 800x600 > foo.ppm
c-ray-mt v1.1
Rendering took: 0 seconds (104 milliseconds)

$ cat sphract | ./c-ray-mt -t 32 -s 800x600 > foo.ppm
c-ray-mt v1.1
Rendering took: 2 seconds (2284 milliseconds)

That's a pretty case, hard to judge scale on the picture though.. Love the faux-tapedrive look, but that's the sysadmin speaking ;-)

Thanks!! Remember to run the other tests aswell though!

Thanks!! 8)

Btw, if I wanted to try C-ray on some of my x86 systems, what would be the easiest/most-sensible Linux-type distro to use? ie. requires the
least amount of farfing around in order to end up with a config that can run the tests?

Easiest would probably be to use some form of bootable Linux system like Knoppix, and run a precompiled 'c-ray-mt' executable from a CD-ROM or USB stick.

For x64 systems you'd want to run a 64bit system and I'm not sure Knoppix is.

Asking which Linux distro is best is a good way to provoke a religious war :lol: Personally, I've stuck to Debian on servers for many years, for a desktop system I usually use something that requires less tweaking, like Ubuntu, or (Open)SUSE. I was pleasantly surprised by OpenSUSE 11.4, it's a little less 'dumbed down' then Ubuntu, but Ubuntu has apt-get. Choices choices :roll:

Here's the c-ray-mt executable I used. It's Intel ICC compiled and should run on any Intel CPU with SSE4.1 or better. I tested it on a Xeon E3120 running Debian 5.0 (x86_64) and on a Core i5 2400S running OpenSUSE 11.4 (x86_64). The Intel compiler is a free download (for non-commercial use).
