ZLUDA CUStream error with heavy Blender projects [CU_STREAM_NON_BLOCKING]

[gioxyer]

With heavy project cuda failed to load viewport render

CMD display error: Out of memory in cuStreamCreate(&cudastream, CU_STREAM_NON_BLOCKING) (C:\Users\blender\git\blender-v410\blender.git\intern\cycles\device\cuda\queue.cpp:21)

Issue with ZLUDA memory

Viewport doesn't loading render

[vosen]

What happens if you render from command line?

blender.exe -d --debug-cycles -noaudio --enable-autoexec -b <BLEND_FILE> -x 1 -F PNG -f 1 -- --cycles-device CUDA

Can you send me the scene?

[gioxyer]

This should be after blender.exe? -d --debug-cycles -noaudio --enable-autoexec -b -x 1 -F PNG -f 1 -- --cycles-device CUDA

I've tried the scene you've attached. I have 64 GB RAM and I'm consistently getting blender crashes with out-of-memory with all GPU backends: CUDA-ZLUDA, CUDA and HIP. Maybe you are running of memory too (errors you are getting also suggest this)?

[gioxyer]

Yes, I tried a few hours ago, I have same problem, after 3 crashes, the fourth time it display "Out of Memory"

[vosen]

I'm closing it, since it does not seem to be related to ZLUDA, but rather Blender running out of RAM.
