OCTANE BENCHMARK: Submit performance scores for your rig!

Hi smicha,

as I also have a netstor turbobox I might help out with your question.

The Turbobox is connected via a PCIe Host Adapter Card... have a look here.
http://www.netstor.com.tw/_03/img/NA255 ... _Large.jpg

This is the NA255A, the one with PCIe Gen3 connections. The NA250A has "only" PCIe Gen2, which also should work with Titans.

The Host Adapter is included with the turbobox as the 1.5m Cable, but only one.
If you would like to connect 1 Turbbox to 2 different PCs or Mobos, you would need at least one extra Host Adapter Card to put in the scesond PC. Not sure, if they sell it separately, but you just might ask.
Or you always have to take out the PCI Host Adapter card and put it in the other pc, which is not a quioet good solution,

But you cannot use one Netstor Turbbox with 2 different PCs at the same time.

Hope that helps,
Greetings,
ChrisVis

As far as I can count you have 5 GPUs and you should run into OpenGL problems. Do you ? If I have more then 4 GPUs Photoshop doesn't have OpenGL acceleration and my 3D package also doesn't have hardware OpenGL any more. To solve this I have put 3 TITANs in SLI and then Nvidia drivers count them as 1 regarding maximum card number for OpenGL. How did you solve this problem ?

Hi boris,

I have 8 GPUs at all... 2 GPUs from the 2 GTX580 and 6 GPUs from the 3 GTX590.

I don`t have OpenGL problems so far or lets say anymore. Since the last NVIDIA driver version 320.18 the GPU selection on different programs actual works now. You can enable just the gpus you want in the nvidia settings menue for common used programs, for example limit the gpus for photoshop or after effects to 1 or 2 gpus... or how much you want. (I had problems using After Effects OpenGL Effects with the netstor in the past)... this option always has been there in the NVIDIA drivers but it never saved my gpus choices after closing, so it didn`t work. Now it does.

Hope that helps.

In Cinema 4D I don`t have problems with the OpenGl preview, so I don`t have to limit it... and can use all 8 gpus in C4Doctane. Usually I use the PC internal GTX580 for OpenGL preview of cinema and the other 7 GPUs (or less to save energy) for octane while working. For final renderings I use all 8 GPUs, when lots of animation work has to be done quickly.

What 3D Package do you use?

How do I set a program to use specific GPU ? I use Lightwave. Photoshop also doesn't work with GPU acceleration so I would need to set this for it too.

I see options to set GPU affinity for CUDA but not for OpenGL

[BorisGoreta]

If I have 6 GPUs in non SLI configuration system does not support OpenGL. I check using this utillity http://www.realtech-vr.com/glview/download.php. It reports OpenGL version 1.1 which is basically software OpenGL. If I put 3 GPUs in SLI then I get OpenGL acceleration, utillity reports OpenGL version 4.3 which is good but then I can't render some scenes because I run out of RAM because of SLI. How do I fix this ?

has anyone ran a benchmark for the 770 yet?

The Gigabyte Windforce OC 4GB, or Palit 4GB Jetstream could be a good value solution if it is indeed 10% faster than a 680 as it is in gaming.

Tomshardware has started doing octane benchmarks, which is great!

The 770 looks to be in-between the 680 and 580.

Thanks
Chris.

Hi BorisGoreta,

I have a non SLI Setup, non of my GTX cards are connected by SLI.
I set the GPU activation with the NVIDIA system control panel, and yes, it is mentioned as CUDA, but seems to affect Open GL, too.
Here for example for Photoshop:

And here the settings in Photoshop (seems to use OpenCL, not OpenGL?):

And here the gpu information of the preview tab in after effects, after only activating one GPU in the nvidia control panel. If I don`t deactivate the other gpus for AE, I have issues while using them in octane or even if they are not in use. Seems like AE cannot handle more then 3 or 4 gpus.

All these pictures were made while my other 7 GPUs are rendering an animation in C4Doctane at full load. So one GPU left for the other programs and somehow C4D handles to use the one left GPU (the GTX in my PC) for OpenGL preview, too. So I can still smoothly browse and work on another scene in C4D while rendering.

I`ll check my Open GL versions later with the utility you mentioned.

Maybe Lightwave handles the GPUs somehow different? Did you try to determine the CUDA gpus with the nvidia control panel for the lightwave.exe?

[BorisGoreta]

Thanks for your report. Problem is that even if I set the global CUDA options to use only 1 GPU I still get OpenGL 1.1 which are only some basic OpenGL functions. When you boot into windows please check your OpenGL version.

Do you have regular nvidia drivers installed or some CUDA special drivers ?

CUDA swithces work for CUDA but have no effect on OpenGL.

I don't understand how can your system have good OpenGL with so many GPUs.

Thanks chris, very helpful. Be nice if they put up the version used too, as the latter Octane release have given Kepler a further boost over the 580

thanks again
