OCTANE API MSG: CUDA error 719 on device 0

[supermac]

Hello,
i don't undersand..
when i render my scene, i obtain this message:

*** OCTANE API MSG: CUDA error 719 on device 0: An exception occurred on the device while executing a kernel. The context cannot be used anymore and must be destroyed. All existing device memory allocations from this context are invalid and must be reconstructed.
*** OCTANE API MSG: -> kernel execution failed (pt)
*** OCTANE API MSG: device 0: path tracing failed
ERROR: [preview image] ----- Rendering failure. Unable to continue


What happens?
i can't render my scene..
my scene is certainly very heavy ..
but I have a Quadro 6000 and a titan X, it's enough no?

I use instance, it's a problem?

Someone can help me please?
Sorry for my english.

Yes, I have seen this cuda error before working with heavy scenes. I know that at least one bug related with this problem has been fixed and will be available in the next build.

Both GPUs have 12 GB of RAM, right? Can you please try to render your scene only with the GPU not used for display? ... if you render with the GPU used for display, some GPU RAM is not going to be available for render because it is used for display, OpenGL and so on.

Anyway, can you send to me the complete log file?

Thanks,

hello, thank you,
no quadro 6000 has 6 gb of memory.
now it work when i change a node.. but i think it's really very unstable..

i try again and give you news..
thank you again.

[juanjgon]

Try to use only the TitanX with this scene to have 12 GB of GPU RAM and see how it works.

but a question.. i read that i can change the TDR (Timeout Detection & Recovery ) or disable..
it's a good idea?

[juanjgon]

When you install the Standalone application, the installer sets a TDR value enough to work with Octane without problems. Try to install Standalone if you don't have it in your system, but I don't think that this problem can be an TDR issue.

ok, i have the standalone.
thank you.

hi,
i have always the same problem.. i have 6 million polygon.. but after 1'000-1'500 sample, octane fail and i have always the same message..
i tried octane 3, but always the same problem..

an idea?

hello everyone,
again sorry for my english..
I have always the same problem.
i use a quadro 6000 and a gtx titan X ASUS..
with 2 card, or 1 card, it's always the same problem..
cuda error
Do you have an idea?
i look for 1 week and i don't found..
please
