I have an AMD RX470 and an RX480 that I have been unable to get working for GPU tasks. I've only used NVIDIA cards for a GPU tasks in the past, but these cards were cheap for the specs. So far, I've had zero luck getting these two cards working with BOINC. I've loaded the AMDGPU-Pro drivers for UBUNTU 16.04 from the AMD website, but they didn't help. Just getting the drivers to work so the machines will boot is a chore. My BOINC logs say they find the OpenCL drivers, but no GPUs are found.

I would like to avoid Windows for this machine if at all possible, since all my other machines are running Ubuntu. The machine also has 4 CPUs, so Windows wouldn't see all the CPUs without running a Server version of Windows.

I've chatted with some folks on the Ubuntu Forums, and only a few have even been able to get their PCs to boot with these cards once they load the AMDGPU-Pro driver and none were running BOINC or other OpenCL tasks.

Thanks,
Greg

Last summer ubuntu 16.04 worked ok with my RX470, even with AMD's first Beta driver for their RX 400 series.

How do the first 30 or 40 lines of your BOINC event log look ? Any problems listed there ?

Even the "amdgpu_test" program supplied by AMD with the driver does not detect the GPU.
'/opt/amdgpu-pro/bin/amdgpu_test'
DRM driver is not available

The "clinfo" program detects only the 24 Opteron CPU cores.

I found a cheap copy of Windows Server 2012 R2 on Ebay, so I'm going to give in a try to see if the cards will work on this machine with Windows.

check your fglrx driver are installed using : dpkg -l | grep fglrx
try to remove nvidia driver if you were using nvidia card before (dpkg -l | grep nvidia ; apt-get remove --purge nvidia*)

Are you running boinc without X server ?
If yes, it's not easy to launch boinc with GPU support.
You need to set a script with :
init /home/user/BOINC/dummy_wm.boinc -- :1
with the following file dummy_wm.boinc :
#!/bin/sh
/home/user/BOINC/boinc --dir /home/user/BOINC >/home/user/BOINC/boinc.log --allow_remote_gui_rpc 2>/home/user/BOINC/berror.log

Standard video output is :0 on linux, so you need to add a separate video ouput :1
If you are using two display (using an extra monitor), you should use :2
It took me a while to find this answer (with the help of google)...if someone have a better idea....

AMD quit supporting the fglrx drivers, which don't work on Linux since Ubuntu version 16.04 was released in April. Older AMD GPUs must use an old version of Linux, and the new GPUs must use the new open source AMDGPU (which doesn't support OpenCL) or the AMDGPU-Pro driver for games or OpenCL crunching. This AMDGPU-Pro driver for the new RX400 cards is only supported on Ubuntu and no other Linux distributions. This new driver is so buggy that most people's machines either lockup with a black screen or go into a endless loop at the login screen that won't allow them to login. After 2 months of work testing the cards on 3 different PCs, I could get the drivers to display a GUI and play videos, but could not get BOINC or any other OpenCl apps to detect the video cards.

I've finally given up getting these AMD cards to work with Ubuntu for the time being. I found a copy of Windows Server 2012R2 for $35 on Ebay and installed it, since only a server version of Windows could access all 24 CPU cores on my motherboard, which has 4 hex core AMD Opteron CPUs.

BOINC saw the AMD RX470 as soon as I installed the Windows drivers for the card! I've only got one video card running right now. Because the PCIe slots were too close on the motherboard for both cards. I've ordered and am waiting on one of those PCIe adapters like BitCoin miners use, which will allow me to get both GPUs crunching.

Warning to others who are wanting to use new AMD cards for crunching on Linux, "Here there be monsters" that will suck up your time like a black hole. It's really a shame, because I've been an fan of AMD CPUs for many years, but they are really not doing well with the support for their GPUs on Linux. They apparently are devoting all their efforts to the Windows desktop and getting their new Zen APUs ready for market.

thanks,
Greg

The shortly released AMDGPU-Pro driver 16.50 is available for all the mainstream distros like Ubuntu 16.04, RHEL 6.8, RHEL 7.3, SLED/SLES12 SP2 (and their clones) Sadly AMD does not say very precise which Linux distros will work. But their amdgpu-pro_preinstall.sh script has about all of them in there (somehow)
Currently i use this driver with my R9 290s on SL7.2 (a RHEL 7.2 clone). Installing the AMDGPU-Pro driver took me only 10 minutes !

The motherboards I'm using are all fairly old SuperMicro H8QME-2 and H8QMi-2 server motherboards from 2006-2009, which may be partly why I'm having problems. A few years ago, I got a dozen of them really cheap, and with 4 hex core 2.4GHz CPUs, they will still crunch, so I still use them. The other people I've chatted with who can't get the RX470/80 cards to work on Ubuntu were upgrading existing machines that aren't new. The NVIDIA chipsets on my motherboards still had support for AGP graphics so that manufacturers could use the same chipsets for motherboards with AGP or PCIe. This causes some confusion for Ubuntu during boot as it tries to allocate an AGP memory aperture, even though the motherboards have PCIe, PCI, and PCI-X slots. Even though they have no AGP slots, Ubuntu logs some IOMMU errors for AGP as it loads. They also have on-board Radeon VGA video. With the jumpers set to disable the motherboard's VGA and installing NVIDIA cards, they've ran BOINC CPU and NVIDIA GPU tasks without a problem.

Since I got these AMD cards to test, I've tried Ubuntu versions 16.04 and 16.10 with several kernels. Once I got around problems that prevented the systems from booting with the AMDGPU-Pro drivers, even AMD's "amdgpu_test" program said "DRM driver is not available". After I installed Windows Server 2012R2 and AMD's driver for Windows 8 this morning, the AMD RX 470 has been cranking out a SETI GPU work unit every 5 minutes and a CPU work unit every 12 minutes.

Since these new AMD Linux drivers only work on their newer GPUs, there likely wasn't much testing of the new drivers and cards with old motherboards. In defense of the AMD driver support people, the majority of the problems reported on the UBUNTU and AMD forums are from users that don't know how unzip the script, open a command prompt, change to the directory, and run the script. The next most frequent problem is that the default GRUB command line often needs to be changed to "nomodeset", otherwise many machines lock up with a black screen during boot or won't allow the user to login. I think that the AMD people who wrote their instructions and the install script were under the mistaken impression that all Linux users were geeks, so they didn't need to over-explain things. They overlooked the large number of UBUNTU users that are non-technical users who simply a want free OS where they don't have to worry about virus infected emails. Real problems with the drivers not working with some hardware configs are simply lost in the mountain of other problems with the instructions and installation script.

I've found my experience with these cards to be ironic. Even though I've worked on UNIX systems since 1983, I could not get these drivers for Linux to work for the past 2 months. I have not used Windows since NT and Win2000, yet I was able to install Windows Server 2012 on one of the machines and get the card crunching in less than an hour. It has been a personal insight into the Catch-22 of lackluster support from hardware vendors for Linux users. Ubuntu is the platform of choice for a majority of Cloud projects, but many organizations that have been using Ubuntu on their own hardware are now rethinking the total cost of ownership compared to using Windows. For Cloud projects, you don't have worry about hardware nor its lack of support, so Ubuntu marches along. For onsite hardware, vendors defend their lackluster support for Linux due to a lack of demand from users, while their poor support forces their customers to use Windows. Governments in Brazil, Germany, Spain and Italy that has chosen Open Source alternatives are now reconsidering Windows.

A Reluctant Windows user,
Greg

Hi,

Rx 480, Ubuntu 16.04, AMD GPU Pro Driver working fine here :
https://setiathome.berkeley.edu/hosts_user.php?userid=5515


I have to admit that it was not easy to get it work together.
Best way :
Install ubuntu server in text mode
Configure the Network and update - upgrade
Install the (already downloaded) AMD GPU Pro driver from usb stick
Install MATE, Genome or whatever Desktop Environment you want
Install Boinc Packages and don't forget to install the the boinc-amd-opencl package.

Works fine but there are no way to change the GPU settings or even see the Temp, Fan RPM etc.
I found a way with sensors to see the GPU Temp but thats all.

Greetings!

I am so happy I found this thread.
I have tried Ubuntu 16.04 and am now running 16.10.
But still having problems.

I can not find a definitive answer about amdgpu-pro support of AMD 7750 card (tried on 16.04)
( The AMD website had a link for a download - but wound up in the No video at boot. (I am not sure where to look for the .sh file))

BUT (on 16.10)
I read the the standard MESA drivers had opencl.
Did not work until I add the package: mesa-opencl-icd
Then, boinc could see my GPU. (Yay!)

BUT
the wu failed right off the line. I was testing with Einstein with their GPU task. Seti tasks were not available.
The error in the task report listen an llvm error: cannot select (etc.) AtomicCmpSwap when it exited witihin one second.

So. I'm asking three things:
-- Anyone getting amd gpu oon 01 March out there? (for me to test)
-- Advice on amd drivers for 7000 series?
-- Should I throw out AMD GPU and get a new nvdia? Do the Ubuntu drivers work for them? cuda? opencl?

I am sad to see that Windows is more viable. :-( but probably so.


THANKS in advance
Jay

Greetings!

I found a answer to my off-tangent question.
http://setiathome.berkeley.edu/forum_thread.php?id=80263&postid=1816642

tells a lot about AMD support on Ubuntu.

Thanks, Jord!

AMD is still a nightmare.

I tried to use my new RX460 for Boinc. The result is a destructed packet manager.
To run the Ryzen-CPU I was told better to use Ubuntu17, which is only as beta available - but runs fine so far.
But then i got the idea to use the RX460 for Seti.
The AMDGPU-pro driver started installation and crashed in the middle, stating that the kernel needs an update, but it cannot find the file for this.
Every update or installation of anything ist now impossible.

I hope, that the final Ubuntu17.04 runs better with the AMD driver. Otherwise i had another AMD GPU fail experience like the many others before.
(But Nvidia isn't better, except that it works without contorted manoeuvres...)

(But Nvidia isn't better, except that it works without contorted manoeuvres...)

Don't know what to tell ya except there are many of us running nVidia in Ubuntu without any trouble.
In fact, the current #2 User at SETI is using nVidia in Ubuntu, https://setiathome.berkeley.edu/hosts_user.php?userid=407, up until recently he was #1.
The #1 Host at SETI is using nVidia in Ubuntu, https://setiathome.berkeley.edu/top_hosts.php
It's very simple now that Driver 375.39 is in the repository. Just install Ubuntu 14.04.5, the Driver, the Berkeley BOINC 7.2.42 with it's One dependency, and the CUDA package here, Linux CUDA 8 Special App
Instant success.

Yes, Nvidia works. Sorry if this was disambigious.
Its more the sum of little things in the daily work with linux (and the fact that i am not a linux expert).
The Desktop is a 1fps-experience when the GPU is working on Seti (in Windows not so extremely and only with OpenCL) - so i have to stop GPU working when i use the PC.
The driver is easy to update, but hard to downgrade. One application was not amused about the change from 8 to 10 bit color depth and i failed to downgrade the driver AND cuda to a working version.
That was the reason i tried AMD again. But at the moment it seems nearly not to work and i hope for the version 17.04 of Ubuntu the next days - last try before going back to Nvidia.

It's not quite so bad with the CUDA App in Ubuntu, as long as you don't try to watch full screen web video ;-) If you keep the video in a normal sized web page, or VLC window, it's watchable. That's with an Older Core2 Quad, it should be better with a newer CPU. With the OpenCL App it is pretty bad, even on my ATI host with the older 6800 cards. The newer ATI cards aren't so bad using the Older FGLRX drivers, I haven't tried the AMD Pro drivers. I usually use the Mac for daily work, and that plays Full screen video without any trouble while running the CUDA tasks. Of course, the Mac has 8 real CPU cores and runs only 4 CPU tasks.
I did forget about the CUDA 8.0 Libraries. You have to 'acquire' the CUDA 8 libs to go along with the CUDA App. I think there is a link in the Linux CUDA Special thread.

I`m running a R9 380 on Mint 18.1 which is based on Ubuntu 16.04 and AMD GPU Pro driver 16.40.
No problems with crunching and watching full size videos at the same time.

With each crime and every kindness we birth our future.

Than i will try to install Ubuntu16.04, but i fear that it will not run on the Ryzen.
Waiting for AMD to deliver a driver for Ubuntu 17.04 is the other option. But for 16.10 (from october2016) there's no driver available until now, this could be a very long time to wait.

---

Try the new AMD driver, is now working for me under Ubuntu 16.10.

Cheers

Ubuntu16 did not find my SSD.
The Ryzen-Mainboard seems to be too new.
So i had to install Ubuntu17 again.
Maybe the new driver will work, its also 17.x, thats a good omen. ;)
Thanks for the news.

Today i installed the new Ubuntu 17.04.
I use the included driver, only added the boinc-client-opencl package.
This was a little bit successful, the GPU is recognized by Boinc. :)
