OTOY Forums

Hi

I currently have a GeForce GTX570 and a Tesla 1060C in my system. While octane is rendering it says I only the GeForce and 1280MB used or available.
I invested quite a bit in this big, badass Tesla and I'm wondering why isn't it "in there kicking butt"?
I asked a similar question earlier and was told the Tesla has great video power/memory--when I enter the CUDA settings, it displays both cards and a whopping 5000+MB of memory. My question is: Where did it go and why isnt it being utilized?

I've included a screenshot

Thank You

Could you please post a screenshot of the CUDA device manager settings?

Thanks,
Marcus

Hi Marcus

Octane stopped working on my machine recently. It was functioning just fine then suddenly, everytime I tried to open the program, it would fail to open. Worse still, the graphic at the startup would just be glued to the desktop and would only disappear upon rebooting, even the task manager could not shut down the application.
I bought a phone card and called you guys up in New Zealand and the gentleman I spoke to said my NVIDIA drivers might not be up to date or confused as I'm running a GeForce GTX570 & a Tesla 1060C. I called NVIDIA today and I was able to get my drivers up to date but still no function from Octane so I tried uninstalling but it wouldnt even respond to that, so I simply deleted the folder and tried to reinstall but now it's telling me I have an administrative rights issue as I imagine there's now some conflict as I've already downloaded it before.

I need to be furnished with a new license, or a refund and I'll order a new one all over again. I was researching other render engines like Indigo but I really want to stick with Octane. I have a brand new machine and as I stated, I have invested quite a bit in video cards/GPU's..things should be running smoothly but for some reason, they're not. I wonder if there is some conflict with running 2 GPU's or the Tesla because, I haven't seen anyone else on the forums experiencing this. While Octane was running, it showed the 570 recognized the Tesla but it was inactive and not being used during rendering. Feel free to remote into my computer if need be, check through it and see that this is authentic.

I'm going to try downloading and installing the demo version right now, hopefully it will function and I'll learn the program meanwhile a solution can be found.

Please reply at your earliest convenience.

Thank You
Isaac

My settings are:
Intel i-7 960
12Gb RAM
GeForce GTX570
Tesla C1060
Liquid cooled
Win7-64 Pro

It is probably a stupid question, but did you look inside the Cuda manager if the Tesla card is actually enabled ?

Halalleujah, I finally got Octane to function. In fact, it was the administrator settings in my own machine that were not alllwoing the program, for some reason, to launch. After "giving myself" full admin rights, it launched.

However, the Tesla card is still inactive. I'm running CUDA version, 3.0 which is supposed to support multi-GPU and as you can see, it recognizes the Tesla's existence but at the moment, it's not recruiting it to render.

When Octane was running earlier, it recognized 5000+MB of memory, not the 1280 currently available( the GTX570's limit). Now...nada.

I've attached the screenshot

Any suggestions?

Thank You

I see on your screen shot that there is an image being rendered in the render window.

You can't set Cuda parameters while the render is running.

Just close your scene or shut down Octane and re-open it without loading a scene, and go back in your preferences and you should be able to select, add or remove the graphic cards in order to enable the Tesla card as active.

Don't forget to save preferences after setting.

I'm almost sure that it will work. Test it and tell us the result !
