Houdini 16 and Nvidia drivers on linux

25 posts in this topic

Just a heads up

Spent a couple days troubleshooting, without luck, even with SESI support to get H16 to launch.

Running latest Ubuntu with latest Nvidia drivers 378.13

Solved the issue. Downgraded my Nvidia driver to 375.39

arrrgh Nvidia drivers.

I am running it with 378 on Ubuntu KDE Neon and it works fine.

What was you issue?

Even on Windows 10  there are OpenCL problems. I see this when I use the Terrain tool. After that failed attempt to create terrain Houdini 16 crashes when I close it.

@Atom that is most likely due to your AMD processor - the error reads that the built-in CPU openCL doesn't support it. This isn't anything to do with the topic of Nvidia and Linux.

Edit: it would be great if you started a new topic with this issue as the new AMD Ryzen processors are looking super and we want Houndini to be able to run on it! Thanks!

SESI confirmed they are working with Nvidia to solve the many driver related issues

I was able to resolve my issue by installing the latest nVidia drivers. I choose the Custom option then checked the box for "Clean Install". This fixed my problem and now I can bring up the terrain via the tool.

The 378 driver issue seems somewhat Linux-distribution specific. I'm running 378.13 with a Quadro K5200 without issue, but another user with the same driver/GPU combo had it crashing on a different distribution.

Nvidia's driver team has hit a rather rough patch for the past 6 months or so. There have been a lot more regressions than usual.

Someone probably left the team or someone new took over work from someone else. It's amazing how much hinges on just a few people in software and technology companies.

Windows doesn't inherently support OpenCL so you have to install software to use it. AMD provides an OpenCL runtime for their processors in one of their SDK downloads. This is might be a moot point if you have a GPU that also supports OpenCL.

@georgeivan Probably worth emailing Support - Linux and Windows should automatically use an OpenCL CPU device and seeing that Atom's didn't, and, he has an AMD chip I suspect you will need to install the AMD CPU opencl drivers.

Well, I've been waiting weeks for this weekend so I can finally play with H16 and no fun for me :/ Windows 7, Geforce GTX580, newest drivers, AMD Phenom processor with the drivers lukeiamyourfather mentioned - I still get errors. In previous Houdini versions OpenCL was working (but didn't increase speed a lot). I cannot use the new terrain tools and stuff. Even if I edit the .env file as Atom did it doesn't help. I've attached a screenshot - just a quick comparison of "about" section in H15.5 and H16.

Geforce GTX580 supported OpenCL 1.1 but it in "platform/profile version" it says 1.2. Or maybe I'm out of the game and need a new card...? :/

Make sure that you're NOT using the 376.XX drivers (which have known problems) but on the 378.XX drivers. After that, try the lastest H16 DAILY build.

Thanks - I'm on the newest drivers (378.78) and it seems the daily build is the same as the one you download from the main link (16.0.504.20).

Linux version doesn't help on Windows, but thanks for that - it shows Linux version are more up to date ;) Yeah - I'm thinking about installing Linux (Mint). Last time I've used it was about 10 years ago :D

I thought you were on Linux

 

Still, the Windows daily version still isn't the same as the launch either
