I actually encountered the same issue with the irradiance shaders. One way I solved this was to tile the renderings. Basically render a subset of the irradiance map and split the queuesubmit calls so the driver never kills the task. I considered changing the driver timeout threshold. But not every pc will have that modification applied.

If, by changing the registry, you mean the Timeout Detection and Recovery registry keys, to my knowledge people just got used to always break up long computations into several short ones because of different issues it was causing. I sometimes think it has become a habit and most people don’t really think about it much anymore... they just avoid it by force of habit... apparently, sometimes, it’s good to be reminded...

This. If possible, can you split the compute shader or the data and do multiple compute passes and then combine the output?

[@jamesmnguyen]

@ As long as the task has independent parts it can be split. In the case of irradiance calculations. Each Pixel of the cubemap is independent. But splitting that far down is bad for performance.

I had a similar problem while running some heavy polymer simulations in CUDA last year. It turns out that depending on the length of my polymer and the number of forces to calculate (that were random by design), the CUDA kernels would drop after 1 or 2 seconds. The solution? I needed to re-structure the memory layout and break down kernel calls. That was actually nice, because the code ran much faster after that. I heard that this is a safety feature. Like so, the work (and the heat) is distributed more evenly over all the processing units.

Came across the compute shader crash a few months ago. We run two computer shaders on startup for our app, once to create a normal map from a height map, and one to set a mask in the alpha channel from a 2d polygon that's represented by a bunch of 2d lines. 2nd compute shader was crashing on some pc's, finally figured out the driver was dying from taking too long. So had to break up the compute shader into a couple of passes. Really makes me question using compute for large tasks if the driver can just crash the application, especially when we don't know the full range of cards our app runs on. A gl/vk call to disable the timeout would be really handy since setting client pc registry settings isn't ideal. Until then, the only fix is to be really really conservative with your compute calls!

[@Feathomable]

I feel you. From time to time our buildserver used to crash from GPU timeouts from environment map filtering as part of a test because it had a slow GPU. Forced us to implement a faster filtering shader in the end.

[@jgurtz]

Finally getting a chance to watch this and I have to say (in devops land), troubleshooting timeout issues in multi-tier apps is one of the more difficult issues that can happen. Here, the timeout is non-obvious and that's just crazy to try to figure out. All timeouts should be well documented, whether in api or part of a larger system!

[@Pakillototaki]

We faced the same TDR crash while working on a Point cloud rendering system. It was super annoying because we set the points buffer to scale with the GPU VRAM (so the "better" the gpu, the more points you get loaded and rendered in a frame) so the crash appeared mostly in high end GPUs. This is the thing with graphics programming... more often than not you feel like you are working in the X-Files, dealing with supernatural forces.

I love the internet so much. You have a problem? Shout it into the void and the void answers. Being a part of this collective knowledge s beautiful.

[@RC-1290]

19:50 this is fairly common. It's a feature of Windows called TDR (Timeout Detection and Recovery) to reduce the impact of GPU operations that hang for whatever reason. You CAN change it in the registry, but that's only really useful for debugging.

[@RC-1290]

As you found out, reducing the time various operations take is the real solution. But if you can't scale down the work-load you can sometimes split it over multiple frames or draw calls. It's somewhat similar to making sure windows doesn't think an application has crashed, by making sure you pump the message loop, except for GPU work, rather than CPU work.

[@bancodrut]

From a user perspective this was also very informative. I have a GTX 770 and I get Device Lost crashes in Unreal Engine 4 games quite often and I didn't knew what could cause this (apparently it wasn't happening that often for everyone). Good to know what's up in the backbone, now I kinda know which settings I might try and tune down in the game settings/config file.

[@roiiam]

best bet for you would be to change registry for Timeout detection and recovery (TDR) and might not need to lower any settings

[@bancodrut]

@@roiiam actually tried that. Didn't helped, it would only freeze for longer (as long as TDR value) so the only thing changing is the driver's time to recovery. Leaving default value there is no freeze just straight crash/hung and recover. As stupid as it might seem the issue was a weirdly unstable overclock (modded vbios) on my end. The weird part is that it crashed only under certain workloads but very dependant on context transitions (sometimes spotted after 1h of gaming, other times after 5h). Quite hard to test for stability there.

I made those two recommendations in the previous video! I'm glad you got to fix those bugs. I had my suspicions that we had the same issue :)

[@Glyn-Leine]

This does sound familiar, I've had this happen before during point cloud generation. It only happened on NVidia cards though for us, and we were using OpenCL which is pretty unstable on Nvidia. we've had to split up the workload into multiple compute shader dispatch calls. On NV OpenCL calls longer than 5 seconds cause a timeout on OpenCL it throws a CL_OUT_OF_RESOURCES and then crashes the driver, and possibly the entire pc... On AMD OpenCL doesn't do anything until 15 seconds and then throws a CL_ERROR_KERNEL_TIMEOUT_TI. This is however configurable on AMD cards. not sure if you can configure it on NV as well. So I recommend doing something similar to what we did and do a little GPU performance analysis at startup to get a general guestimate, then we split up the compute calls into multiple smaller dispatches. we start with one we guestimated we could handle and slowly increase the size until we reach a sweet spot. yes, your compute dispatches will be slightly slower, but they'll be stable.

[@BlenderhilfeDe]

yeah driver timeouts are horrible... we had this problem in blender too with gpu-raytracing in cycles... on complex scenes it will trigger a crash if a compute-cycle is taking to long in cuda/opencl

[@antonrr90]

Blender3D used to have "Hung GPU" problems all the time. "NVidia Timeout Settings" were capped at 2.0 sec. "Windows GPU Timeout" set at 2.0 sec. Renders with high memory usage by zone would take upwards of 4-5 sec. which would crash the driver. you would have to restart the driver, and in some cases restart the computer, because the driver would hard-crash. Nvidia was the biggest culprit, since you had to edit the Timeout Settings in a text editor, because it was not available in there shell application. Took we too weeks to track down a forum discussion pointing to the settings that needed to be changed.

[@p250185]

Device lost is not a driver crash, it is a TDR. TDR occurs when DMA buffer execution takes too long (more than TdrDelay value, which is 2 sec by default). PageFault is not a driver crash. It is a Gpu hang, also visible as Tdr because in this case Gpu can't read the memory properly so it can't proceed next commands, so it goes into 'idle' state and currently executing DMA buffer time is > TdrDelay. Driver crash occurs when you pass invalid data to the API.

[@JohnAmanar]

Great video! Yeah, the timeout registry setting was also required for Unreal's GPU lightmass calculations.

[@joebhomenye]

if you want to be able to do the same amount of compute work while avoiding a timeout, break your compute task into smaller passes and use commandBuffer per pass (add a barrier between each pass to preserve your read & write order) so each level of your radiance cube map will run on its own commandBuffer

[@bigmistqke]

That feeling when making a breakthrough when u bounced against a wall for so long... Bliss.

[@taw3e8]

I've actually met with this issue before while using some programm and the solution was to change the waiting time to a higher value in Windows paging files if I remember correctly

[@AndrewCJP]

GPU's need run multiple jobs at the same time (especially on windows), So a job (like a VKCommandBuffer) is scheduled in smallish chunks. The GPU needs to limit the time taken for a context to drain/complete the chunk so it can switch to another context (for instance a Windows OS Job). This is similar to thread scheduling on a CPU core. Without this scheduling approach GPU operations would execute sequentially so the OS wouldn't be able to update the desktop while a game was rendering a frame. The main causes of Device Timeout/hung are: too complex compute shaders, certain memory faults or rendering super large triangles.

[@jamesmnguyen]

After some experimentation. The GPU divides the work by vkQueueSubmit. Which was kinda annoying since I like to send a whole bunch of cmd buffers all at once.

[@AndrewCJP]

@@jamesmnguyen Sort of. It is actually recommended (on both VK and DX12) to submit multiple cmd buffers in a single VKQueueSubmit to minimise the driver scheduling overhead(and allow some driver optimizations). The chunks of work only contain a few shader executions (compute or graphics) that have the same pipeline/GPU state set. A PSO change can cause the context to "Roll" as the GPU hardware needs to change configuration (for example, enable blending hardware unit) , causing a context switch at the same time.

[@jamesmnguyen]

@@AndrewCJP That explains why trying to submit work too many times locks up my OS.

[@TheDonsky]

I've faced the "compute shader taking too long" crash quite a bit frequently when working with CUDA. I've implemented an accelerated offline renderer about 3 years ago and that driver crash came up quite frequently. To get rid of the issue, you just open Nsight Monitor options (if you have that one installed) and change "Microsoft Display Driver" settings for that timeout. However, I would not recommend it. Haven't yet touched anything compute related with my "infant" Vulkan engine just yet, but with CUDA I was literally unable to move windows around when the compute kernels took too much time and the system was terribly unresponsive (I too have a GTX 1080ti, but once again, it was an offline renderer and the case was far worse for me because of the constant load that came with it). Just split the job into multiple dispatches and it should be both smoother and more stable. Kernel launch overhead is a real thing, but it's not that hard to strike balance and still maintain 99% of the performance, at least from my limited experience.

Far as I know, the GPU can't do literally anything else at all while your shader is running. If your shader takes 30 seconds the user's computer is, effectively, completely frozen for 30 seconds (because the screen is frozen). That's why the timeout is short.

[@MatyyRdk]

They initially thought it was going to wipe the floor with Phenom. It didn't. Shouldn't buy it unless all you needed was strong multi-threaded integer performance for an incredibly low price, which it did great. Any other case? Nah. AMD right now is actually doing better in some workloads than Nvidia. Plenty of games in 1440p run faster on their top card than Nvidia's and with lower power usage. Might actually be new to you, because Nvidia's mind share is so big with RT and DLSS, which are actually quite minor features for this generation in the big scheme of things, that nobody even considers that they have the fastest card in quite a few scenarios. And AMD has given the development community a lot through GPUOpen. Problem is it often works on Nvidia too, so it's no selling point. I would rather fund that than Nvidia's approach, even though I am a customer of both. Nvidia is like Apple in that regard, they make sure their users are balls deep in their tooling, software and hardware, so that even if AMD makes the better product, they still won't switch.
