art3mis Posted February 25, 2017 Share Posted February 25, 2017 (edited) 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.

SreckoM Posted February 25, 2017 Share Posted February 25, 2017 I am running it with 378 on Ubuntu KDE Neon and it works fine. What was you issue? Quote Link to comment Share on other sites More sharing options...
Atom Posted February 25, 2017 Share Posted February 25, 2017 (edited) 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. Edited February 25, 2017 by Atom Quote Link to comment Share on other sites More sharing options...
Guest tar Posted February 25, 2017 Share Posted February 25, 2017 (edited) @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!

Diego A Grimaldi Posted February 26, 2017 Share Posted February 26, 2017 Had no issue on Ubuntu Mate with H16.0.504 and Nvidia 367.57 Quote Link to comment Share on other sites More sharing options...
art3mis Posted March 2, 2017 Author Share Posted March 2, 2017 SESI confirmed they are working with Nvidia to solve the many driver related issues Quote Link to comment Share on other sites More sharing options...
Atom Posted March 2, 2017 Share Posted March 2, 2017 (edited) 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.

malexander Posted March 2, 2017 Share Posted March 2, 2017 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. Quote Link to comment Share on other sites More sharing options...

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. http://developer.amd.com/resources/articles-whitepapers/opencl-and-the-amd-app-sdk-v2-4/ http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/ Quote Link to comment Share on other sites More sharing options...
Guest tar Posted March 2, 2017 Share Posted March 2, 2017 @lukeiamyourfather Ya - H16 ships with a built-in CPU openCL but it must be only for Intel CPUs - or that's how I understand it. http://sidefx.com/docs/houdini/news/16/dynamics Quote Improved Built-in Intel OpenCL driver with CPU fallback for simulation on the farm.

georgeivan Posted March 3, 2017 Share Posted March 3, 2017 (edited) Sorry guys i dont understand i, have a gtx1070 with an Intel CPU.If i buy a Ryzen CPU i cant use OpenCl? Edited March 3, 2017 by georgeivan Quote Link to comment Share on other sites More sharing options...
Guest tar Posted March 3, 2017 Share Posted March 3, 2017 (edited) @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.

loogas Posted March 12, 2017 Share Posted March 12, 2017 (edited) 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...? :/ Edited March 12, 2017 by loogas Quote Link to comment Share on other sites More sharing options...
edward Posted March 12, 2017 Share Posted March 12, 2017 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. Quote Link to comment Share on other sites More sharing options...

loogas Posted March 12, 2017 Share Posted March 12, 2017 (edited) 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).

vtrvtr Posted March 12, 2017 Share Posted March 12, 2017 I thought you were on Linux Still, the Windows daily version still isn't the same as the launch either Quote Link to comment Share on other sites More sharing options...
