Message 50217 - Posted: 17 Aug 2013, 6:58:29 UTC

I have always had this message, but I recently upgraded my video card to a Radeon HD6750 and according to documentation on this site, this GPU is usable. So how do I make it happen ?

I'm running Linux Fedora 19 and installed Boinc from the repositories so boinc is happily running from /var/lib/boinc

I really don't want to use the Berkley BOINC installer because that created all sorts of problems for me in the past.

I have tried all of this ...http://boinc.berkeley.edu/dev/forum_thread.php?id=8129#47188 to no avail.

I tried putting symlinks in /var/lib/boinc to the various libraries - though I couldn't see why that would work - and it didn't.

Any further suggestions ?

OK. Tried all that, it doesn't work.

Fedora is not exactly the same as Debian/Ubuntu in the way it starts things - it's running systemd, and doesn't use /etc/init.d but I went through the same processes of starting/restarting the boinc-client after making changes, and it affected nothing. Still got ... No usable GPUs found

OK. Got a bit further with this, the GPU is now recognised. What exactly makes the difference I don't know, so some of the following may not be necessary.

The set up is Fedora 19 with the AMD Catalyst Beta 13.8 driver.

I have NOT disabled Selinux. Some users advocate it - it isn't necessary.
I have NOT modified the firewall.

I added boinc to the video group.

There's a bug in the 13.8 beta driver which means access rights to the device are not set correctly and so for example the AMD Catalyst Control Centre program does not start unless you are root. We don't like being root, so you need to enable access to /proc/ati with a chmod -R 777 /proc/ati

To allow this to happen, and to make sure the video drivers are there before boinc starts I amended /usr/lib/systemd/system/boinc-client.service with the following lines...

ExecStartPre=/bin/sleep 20
ExecStartPre=/usr/bin/chmod -R 777 /proc/ati

i.e. changed the sleep from 1 to 20, and added the line to change permissions.

I also added the following line to allow the Xserver realise that boinc is allowed access to the GPUs

ExecStartPre=/usr/bin/xhost local:boinc

Boinc now starts up and says I have a GPU ...

So, there it is. Whether it's actually being used is another question.

Hmmm, I just noticed it says I have a HD 5700 series. But ...

That's because the detection code in BOINC only sees the HD5700 as a Juniper. I sent in code to the developers that adds the HD6750 and HD6770 as well. That'll be added in a future version of BOINC.

Hmm, well something is still not right, because I'm not getting work units. Here's a log. Einstein thinks the driver doesn't support OpenCL ... or I've set things up incorrectly.

Hmm, well something is still not right, because I'm not getting work units. Here's a log. Einstein thinks the driver doesn't support OpenCL ... or I've set things up incorrectly.

Well, that's correct when the only thing in your start up log is the CAL: ATI GPU 0: ATI Radeon HD 5700 series (Juniper) (CAL version 1.4.1848, 1024MB, 964MB available, 50 GFLOPS peak) line. The CAL in front of it shows that the only detection BOINC could do was of the older CAL format.
The OpenCL detection will have a separate line, like so (from my machine):

8/27/2013 3:42:05 AM | | CAL: ATI GPU 0: AMD Radeon HD 7850/7870 series (Pitcairn) (CAL version 1.4.1741, 2048MB, 2008MB available, 6400 GFLOPS peak)
8/27/2013 3:42:05 AM | | OpenCL: AMD/ATI GPU 0: AMD Radeon HD 7850/7870 series (Pitcairn) (driver version 1214.3 (VM), device version OpenCL 1.2 AMD-APP (1214.3), 2048MB, 2008MB available, 6400 GFLOPS peak)

So the AMD drivers should contain the OpenCL part and BOINC should be able to read the correct library, in the case of Linux libOpenCL.so

OK. Thanks for clearing that up.

According to the AMD site, the driver can do OpenCL. I've got some Open CL libraries installed with the same date as when I installed the driver, so I guess all I have to do now is work out why boinc can't see/use them

Boinc detects my GPU OK. But it doesn't realise it can do OpenCL. The relevant lines of the startup log are ...

I have OpenCL 1.2 libraries. "clinfo" tells me that.


    [mike@ceri monitor]$ clinfo
    Number of platforms: 1
    Platform Profile: FULL_PROFILE
    Platform Version: OpenCL 1.2 AMD-APP (1272.2)
    Platform Name: AMD Accelerated Parallel Processing
    Platform Vendor: Advanced Micro Devices, Inc.
    Platform Extensions: cl_khr_icd cl_amd_event_callback cl_amd_offline_devices



I understand that boinc cannot look outside its' environment, so in /var/lib/boinc, I've set up some symbolic links.

[mike@ceri monitor]$ ls -al /var/lib/boinc/lib*
lrwxrwxrwx. 1 root root 19 Aug 30 15:25 /var/lib/boinc/libaticalrt.so -> /lib/libaticalrt.so
lrwxrwxrwx. 1 root root 19 Aug 30 15:26 /var/lib/boinc/libOpenCL.so -> /lib/libOpenCL.so.1
[mike@ceri monitor]$ 


I've also tried pointing to the 64-bit libraries of the same name.

boinc doesn't detect that my drivers can do OpenCL.

What else do I need to do ?

Thanks

I did a search through the forums and found this post which you may try to follow. That's for Fedora 17, but I just assume Fedora 19 to work the same way.

Apropos, you did install the videocard drivers from AMD? Although, of course, according to their release notes your OS isn't supported. ;-)

Now, do know you're not the only one with problems. In this thread, jay-e has a lot of head scratches. I'm not sure if he finally manages to get his GPU to be detected.

Message 50364 - Posted: 30 Aug 2013, 22:02:42 UTC - in response to Message 50363.  

I did a search through the forums and found this post which you may try to follow. That's for Fedora 17, but I just assume Fedora 19 to work the same way.


Unfortunately not. Fedora 17 used the "normal" /etc/init.d stuff. Fedora 19 has gone to using systemd. That thread did lead me to the "xhost local:boinc" statement though, and for some reason it does not work with systemd. The command is there, but it fails "no protocol specified" - the error never comes out on a logfile anywhere - I only discovered it by putting in a lot of status and error checking code. To be fair it doesn't make much real sense to have a boot time service depending on using graphics drivers, when there may not be a graphics card at all in the system. That said, if after the system is up and running I manually do a "xhost local:boinc" command, and then restart the boinc-client service, boinc does see my GPU. It just doesn't see any of the OpenCL stuff.

My current thinking is to set up the LD_LIBRARY_PATH before the boinc starts and see if that makes a difference.


Apropos, you did install the videocard drivers from AMD? Although, of course, according to their release notes your OS isn't supported. ;-)

Now, do know you're not the only one with problems. In this thread, jay-e has a lot of head scratches. I'm not sure if he finally manages to get his GPU to be detected.


Err, yeah. I think a part of the problem is that Fedora is always cutting edge. It is now running kernel 3.10.9-200, and the stable ATI driver does not compile/install. I have to use the beta driver. There are known bugs in it with privileges on the /proc/ati device. Maybe there are other things I've not detected yet with this beta driver.

So, my current state is, the GPU is detected, but not the OpenCL

OK. Got a bit further with this (again). In fact I've SOLVED it.

By enabling the <coproc_debug>1</coproc_debug> flag in cc_config.xml I got a few more messages in boinc.log.

So, by looking at the source code for boinc, the "No OpenCL library found" text only appears twice, and both occurrences are in ./client/gpu_opencl.cpp, once for Windows and once for everything else that isn't Apple - so that's me, and the code looks like ...

#else
//TODO: Is this correct?
    opencl_lib = dlopen("libOpenCL.so", RTLD_NOW);
#endif
    if (!opencl_lib) {
        warnings.push_back("No OpenCL library found");
        return;
    }


I built the source code I had for boinc from git, and added a call to dlerror() to get the particular error. I got this ...

Aug 31 18:46:12 ceri boinc[25731]: 31-Aug-2013 18:46:12 [---] libOpenCL.so: cannot open shared object file: No such file or directory. No OpenCL library found

To after a bit more debugging. I discovered that boinc DOES NOT LOOK in /var/lib/boinc for the ATI and OpenCL libraries. It really uses LD_LIBRARY_PATH.

Amend /usr/lib/systemd/system/boinc-client.service to include the line.

Environment="LD_LIBRARY_PATH=/usr/lib64:/lib64:/usr/lib:/lib:/usr/local/lib"
... or where ever your libraries are.

Then make sure you library is libOpenCL.so and not - as was my case libOpenCL.so.1. There's something odd with symlinks here - it appears as if symlinks are ignored by dlopen(). You need a real library without the version number

And it will burst into life.

Great! If you make a post about that in the GPU forum, I'll sticky it.
