Standard Candle
on Jun 23, 2011 at 11:10:57 am

Hi guys ,

I like benchmarking , and of course we all want to know if our triple 4800 Setup still can beat the Hackintosh guys out there, right ?
So, I sat down and tried to develop a non-disk-all-GPU benchmark for us to use.
Or as the astronomer would say :

"A standard candle is a class of astrophysical objects, such as supernovae or variable stars, which have known luminosity due to some characteristic quality possessed by the entire class of objects. Thus, if an extremely distant object can be identified as a standard candle then the absolute magnitude M (luminosity) of that object is known."

This is the link to the Resolve project :
https://www.yousendit.com/download/MFo1ckhlZDU5RlpFQlE9PQ

The images used are the "Sample Images" from the Installer .
Copy the folder somewhere , import the project and relink the files.
The project consists of the three clips with some settings applied.
Its a standard project with standard HD 24PsF settings and the images will be scaled up to fill.
I created nodes with some color, blur mask and either blur or sharpening.
The memories A-H are filled with repetitions on the same nodes.
The higher the letter, the more nodes.
On my GT120/GTX285 system I can use setting A and B with 24fps, from memory C on it drops frames .
That is 5 nodes...Memory H has 20 or so, but it seems you can add more nodes without drastically reducing performance.

This is just a first draft and I am open for suggestion to make it more elaborate.
But please give it a shot and lets share results..

Have fun testing.

love your idea...

but i am unable to import the xml-file. i cant do this in resolve 7 i guess and my fcp drops some
error message... so i cant participate...

plz post a standard resolve project, or gimme further instructions, perhaps i overlooked something.

Go the project tab, right click the project window, say " import+" and select the .tar.gz file.
Resolve will import the project for you, you just need to reconnect the media then .

Make sure Safari doesn't uncompress/rename the file for you when it finishes downloading.

i think resolve expects it to be in the compressed format before if will let you import the project.

I just opened this up and the memories are empty. Not sure why - is it possible A-Z don't get exported? Maybe it's better to make some stills?

The grades are there though so I can just duplicate the nodes for the same effect.

hi again!

thanks, now it works. but as vladimir mentioned, the memories are empty... :(

and, i cant duplicate nodes, can i?

playing back the test (first 2 nodes, second 4 nodes, third 6 nodes) i have 24 frames.
maybe you could upload another version of the test with more nodes as scene 4, 5 and so on?

my spec: double gtx480 :)

Andy, try grabbing a still, and then open the still's node graph. You can from there drag nodes into your grade over and over.

thx.

you are right, i can.

now the parrot i can playback with 9 nodes max until i get a lower fps than 24:

9 nodes - 24fps
10 nodes - 22
11 nodes - 20 to 20.5
12 nodes - 18.5 to 19

20 nodes - 13 fps

and ps: i do only have two gtx480 right now, so one does the gui (and perhaps helping with cuda?) and the other one is purely for cuda. if i have some time i will get a cheap third card for gui.

Cool, that sounds like the double performance I have with my "standard" setup.
It would be great if more people could do tests and share results, especially Cubix DUal card setups and one card solutions are interesting then.

I'm getting the exact same results as Vladimir. Running 7.1.2 on a 12-core 2.66, except I have a 5770 for the gui and a Cubix with 2 Quadro 4000s in it. Odd. Resolve reports 2 GPUs in the "about" screen.

5 nodes - 20fps

Hi all,

Do you get higher frame rate if you set Proxy Mode to On ?

Hi Everyone,

Cubix Engineering has run benchmark tests with 1-4 x Quadro 4000 for Mac on GPU-Xpander Desktop 2, Desktop 4, and Rackmount 8 models. I'll ask my engineering department to forward this information to me, or post it directly to this thread if helpful.

Thanks to this test I discovered that I was getting reduced performance from the host adapter connected to the Cubix. Reseating all the cards and connectors, I can now get 6 nodes at 24fps, 7 at 20. This is with a Desktop Pro 2 and 2xQuadro 4000.

Eric, would I get more with the Desktop Pro 4? Do I understand correctly the Pro 2 slots have x8 electrical and the Pro 4 x16?

Hi Adam,

GPU-Xpander Pro2 / Desktop 2 was limited to 40Gbps on 4-slot configurations, even with PCIe x16 HIC (Host Interface Card) connections to Mac Pro's x16 slot. Desktop 4, with the Cubix part numbers referenced by DaVinci with the release of Resolve 8, natively supports 80Gbps bandwidth. This same 80Gbps 4-slot PCIe backplane is also used with the GPU-Xpander Rackmount 8 model (2 of them in a 4U rackmount enclosure).

When installing the hardware, keep in mind that PCIe connections can be sensitive to bumps and jostling. One of the first support procedures we ask customers to perform is to reseat the 3rd party I/O cards, the Cubix HIC, etc.,. This solves 90%+ of the PCIe link questions we receive when customers are installing equipment.

I'll have Cubix's Technical Support Manager, Mic Grover, add any additional tips to this forum once he returns next week from his vacation in the South Pacific (lucky bastard!).

After setting the playback speed to 100fps to get a better overview for the lower nodes;

"2 nodes" - 61fps
"4 nodes" - 40fps
"6 nodes" - 29fps
"12 nodes" - 16fps

"NR4" - 48fps
"NR3" - 32fps
"NR2" - 16fps
"NR1" - 5fps

This is on a Hackintosh with Nvidia GTX (OC) 480 for GUI, GTX 285 for GUI, Decklink HD Extreme 3D, i7@3.8GHz on X58 mobo with 6GB RAM and reading media from a 4 drive RAID0 that has 540MB/s I/O.

With this test I get 24 fps with 7 nodes which I am more than happy with, anything over 7 nodes and I'll use the render caching.

Can't wait to see single GTX 580 results if anyone gets that working!

Future system will be Dual-GPU (hopefully dual 580 on LGA2011 board).

All we need now is better processing for cheap real-time half-red RED debayering! I'm getting a 6-core soon and hoping to go to 4.2 GHz which might get me close! Will keep you guys posted.

p.s. LOVING 8.01 (-:

Hey Sascha,

Any chance you can re-post this project so i can do a comparison between my 285 and the 470 i just got?
