Not sure if it is because of octane plugin or the cuda and windows 10 updates.
We are running windows 10 version 1709 and cuda 388.31
Latest octane 3.07 and plugin R2
We have usually 4 x 1080 TI but removed one card in order to see if it has to do with oversaturated PCIE bus - but no change.
Any help or ideas are much appreciated.
I attached screenshot and log file from the crash that occurs.
According to the log the Windows TDR
(Timeout Detection and Recovery) has kicked in. The default is 2 seconds (see https://docs.microsoft.com/en-us/window ... istry-keys
). I.e. if a kernel call takes longer than this time, Windows pulls the plug and kills the driver and with that CUDA dies.
The kernel run times are heavily dependent on the scene, i.e. it might be an issue particularly for this scene.
If you don't want to change the TDR
settings manually, you can install the Octane Standalone via the Windows installer, which will change the TDR
timeout to 10 seconds. To make the registry change effective, you have to reboot Windows.
If this didn't help it's probably best if you send us the scene and a description of how to reproduce the problem. We will have a look at it then.
