Message 51029 - Posted: 26 Oct 2013, 4:55:44 UTC

This is not a new problem, but finally I decided to report it as I couldn't find a solution. I have AMD Radeon HD5850, which I believe is supported, but my GPU is not used. The message in the log is "No usable GPUs found".

Below are a little edited messages from the log file.

I used to run the client as a service, but reinstalled to be run under regular user account a long time ago, but that did not solve the problem. It is not run in a virtual client, even though VirtualBox is installed on my machine.

My video driver is 13.9 (well, not exactly the driver version, but package version) so it's quite recent.

Is this a bug in the detection process, or something wrong with my system?

Where did you get it from? If not from AMD themselves, then go there first. Drivers provided by Windows lack the OpenGL and OpenGL components that are needed for the detection of the GPU.

Yeah, the drivers were always downloaded from AMD web site. GPU-Z does NOT show check mark next to OpenCL and MSI Kombustor reports OpenGL version as 4.2.12430. I was looking for opencl.dll file and there are several on my system, including one in System32 and one in SysWOW64 directories. I bet there are more files needed, but what are they and where should they be? Thanks.

What you can try to do is completely uninstall the videocard drivers and remove its remnants from your system, before installing them fresh. That way any old driver remnants, or drivers from another videocard won't be in the way.

See the How to completely clean out drivers of GPUs you do not use anymore? FAQ for more on that. Also see the Determine OpenCL capability GPU and CPU FAQ.

Thanks, but I don't think this is a driver problem. I've never had any other display adapter in my system and all drivers were downloaded from ATI (now AMD) web site. My system seems to be somewhat unique (I don't know why, maybe it's a number of apps I've installed), but I've had instanced before where commercial programs had issues running on my system. I won't mention MiMedia, because they have lousy programmers/software architects (I know that because a loooong time ago I used to be a programmer), but even Nero Burning ROM was crashing when certain menus were selected. I don't blame them for not trying very hard to debug their application, at least they offered a refund.

Having said this there may be a different way required to detect the display adapter in my system. If you have a debug version of BOINC that I could run, that would create a detailed log of all relevant API calls and their return codes, I'd be happy to run it.

Here is some info that may show that driver isn't the issue (I believe).

I'll skip for now the complete driver reinstallation as in the past similar exercises didn't produce the expected results.

Message 51080 - Posted: 29 Oct 2013, 17:11:51 UTC - in response to Message 51070.  

Thanks, but I don't think this is a driver problem.

I kindly disagree. When BOINC can't detect the GPU, it's 95% of the times that people installed BOINC as a service, 4.95% of the time that people didn't install the driver, installed the wrong driver, or neglected to clean up after the driver uninstaller. The other 0.05% of the times it's a bug in BOINC.

Having said this there may be a different way required to detect the display adapter in my system. If you have a debug version of BOINC that I could run, that would create a detailed log of all relevant API calls and their return codes, I'd be happy to run it.

There is no debug version for that. It works on many people's systems, so it should as well on yours, as long as all the right drivers are installed.

Here is some info that may show that driver isn't the issue (I believe).

These are all drivers used by your AMD CPU !!

And finally the log file from clinfo.exe:
Device Type: CL_DEVICE_TYPE_CPU

Which shows that your CPU is OpenCL capable, and that's it.

I'll skip for now the complete driver reinstallation as in the past similar exercises didn't produce the expected results.

So then the solution is easy: don't run with a GPU.
It is really that simple, the driver that you installed for your videocard either lacks the OpenCL component, or it was installed wrong, or remnants of the previous driver are in the way. Now, you can complain about it and stuff, but had you just spent the 15 minutes of cleaning out all drivers and reinstalling them, I'm sure it would've been fixed already. You can also use the AMD Uninstall Utility.

And wonder for yourself if the driver you installed was for your videocard, and not for your AMD CPU.

My AMD CPU? Where did you get this information from? I think the info I posted clearly shows that I have Intel CPU. Anyway, it was a driver installation problem. Point for you. Problem solved? Not really.

It took me way more than 15 minutes and several reboots and manual deletion of a file that Driver Sweeper tried several times to remove, but it couldn't. Why? I don't know. It wasn't locked.

After driver reinstallation and another reboot it seemed like a success.

My AMD CPU? Where did you get this information from? I think the info I posted clearly shows that I have Intel CPU.

Point back for you. My mistake. The clinfo information you posted in this thread showed that the OpenCL at that time was only available on your CPU. I misread your CPU, thought it was an AMD Quad. I blame my reading glasses.

How do you explain this?

Errr, looks like something on your system eats necessary driver files. Else I cannot explain why it does this. Any special anti-virus software you use?

But here's an option to force things.
Please go to this page and download the Accelerated Parallel Processing (APP) SDK 2.8.1 for Windows.

(It's a slow server, so have patience when trying to download the zip file)
When it's done downloading, unzip the contents to somewhere easy to reach, and then start the executable.

Edit1: Apropos, if the installation is giving you problems with one of the samples not being able to install, then install using Express mode (it's an option in the installer). In the populated list of stuff to install, deselect the Sample applications. Then continue installation.

Afterwards exit & restart BOINC, or reboot the system.

Edit2: Another later thought of question, can you please test with BOINC 7.2.26 as well? It's slated for release on Monday.

OK, I must say that adding the APP SDK v2.8.1 does not make your system more stable. Not in my case at least. I was forced to remove it because Windows Explorer would crash every 10 minutes, my NIC driver would go lost and leave me without LAN and internet and my system was very slow.

Just trying to remove the APP SDK resulted in always removing all OpenCL from my system as well, so I resolved that by running the AMD Cleanup Utility, rebooting and at the 800x600 screen install the 13.9 Catalyst drivers. Rebooted again and my system seems all the more stable now. I haven't seen Windows Explorer crash yet, so that's positive.

Same thing. The "driver" or whatever it is doesn't last more than 1 reboot. I backed up files from directories used by the driver and compared them after driver was reinstalled and after several reboots. The files are the same, the only difference was older clinfo.exe, but this should not matter. It must be something in Windows registry that gets screwed up.

I had the previous version of AMD APP SDK installed (v2.8) that I installed a few months ago as a part of troubleshooting of the GPU issue. It didn't help then and the new version that I installed after new client didn't help, also did not help.

Is there a way to force usage of certain GPU? It seems that cc_config.xml file may be used for exactly this thing. If so, how should it look for my GPU?

Well, the above at least shows that the AMD-APP driver was kept in place, since your CPU is still being detected as OpenCL capable. So we know the OpenCL driver is still in place. Now we have to wonder why the GPU will no longer be detected. I'm posting this onto the BOINC Alpha and development email lists. Perhaps that someone there knows.

Is there a way to force usage of certain GPU? It seems that cc_config.xml file may be used for exactly this thing. If so, how should it look for my GPU?

No, the core client configuration file will only be of use when hardware has already been detected. It won't be able to force the use of unknown hardware either. The most you can set is the <coproc_debug> flag, to see if it says something about what happens.

Might not be a bad idea.
Make cc_config.xml file in your BOINC Data directory C:\ProgramData\BOINC\
Just use Notepad to add the following lines:
<cc_config>
<log_flags>
<coproc_debug>1</coproc_debug>
</log_flags>
<options>
</options>
</cc_config>

In Notepad:
Click File->Save As...
-> Navigate to C:\ProgramData\BOINC\
-> Set "Save As type" to All files
-> Encoding: ANSI
-> File name: cc_config.xml and then click Save.
Check that the file does only have the .xml extension. If by chance it's .xml.txt rename it so it's only .xml

Now exit & restart BOINC.
Then post the first 30 messages of the start-up log again.

Message 51197 - Posted: 7 Nov 2013, 15:36:17 UTC - in response to Message 51193.  

While waiting for the coproc_debug log, here's some random questions.

Do you use remote desktop? Fast user switching?
Do you have multiple monitors? KVM? Video chip built into chipset? If yes to any of those how is it configured?
Does Windows Event Log have anything relevant?
What AV suite you have and is there anything in it's log(s)?

You wrote:
My system seems to be somewhat unique (I don't know why, maybe it's a number of apps I've installed), but I've had instanced before where commercial programs had issues running on my system. I won't mention MiMedia, because they have lousy programmers/software architects (I know that because a loooong time ago I used to be a programmer), but even Nero Burning ROM was crashing when certain menus were selected.

It took me way more than 15 minutes and several reboots and manual deletion of a file that Driver Sweeper tried several times to remove, but it couldn't. Why? I don't know. It wasn't locked.

It must be something in Windows registry that gets screwed up.

Riiiight!! Excuse me for putting this bluntly but how much malware do you have on your system?

Do you have some special "system protection" programs. Or "optimizing" programs? Or whatever there's on the net that breaks otherwise working OS?

Is there a way to force usage of certain GPU? It seems that cc_config.xml file may be used for exactly this thing. If so, how should it look for my GPU?

If GPU-Z and clinfo don't find OpenCL support for your GPU then science applications won't either so forcing BOINC to use the GPU would be useless.

saw this once, boinc started before the gpu drivers were fully loaded.
fixed it by <start_delay>30</start_delay> in cc_config.xml

Nice, but <start_delay> does not delay the startup of BOINC. It merely delays the startup of any science applications after BOINC has already started. Like so:

07/11/2013 18:47:03 |  | Suspending computation - initial delay

So that won't help much as the GPU detection has already happened.

The only start-delay one can add to an automated start-up is by either:
1. Installing BOINC as a service, then at services.msc you an state how long the service has to wait before it can start. The problem with this is that by installing BOINC as a service, you won't be able to use the GPUs due to drivers being in one session and BOINC being in another.
2. Using a batch-file to point at the client. In the batch file you can then set e.g. the pause command, which will wait for anyone to press a key. Or else set up a wait for several seconds visual basic script. Examples here.

And not automated:
3. Not start BOINC at Windows start-up. In BOINC Manager, Tools, Options, uncheck "Run at manager login?", OK, and then manually wait for the system to fully start up and start BOINC. For instance with a quick link to BOINC Manager in the quick launch bar.

That sort of solution seems to be commonly needed under Linux, but I've never found any problem like that with Windows.

I run some older (Windows XP, BOINC v6) machines with GPUs and BOINC service installs: other newer machines with an AutoAdminLogin so there's no startup delay. Neither group has ever missed GPU detection on startup.

No, I don't think it's something like that either. As far as I know, the videocard drivers are loaded pretty early in Windows start-up, way before you even see the desktop.

I had this issue a few times on old 4350's. It made no sense. However, after multiple repeats of full uninstall, reboot, reinstall, reboot procedures, it just eventually started working. I had this happen on 3 different systems using the 4350 over the years. (I typically avoid AMD video cards) Their drivers software has been buggy as far as I can remember. Even in early 2000 my previous Computer Repair bosses would tell us that we had to get it right the first time or it was heck to get ATI drivers right. Mostly had to do a clean driver wipe even after an uninstall to get them to work. So, don't give up.

That's all right, but the <delay_start> option does not delay start BOINC. It merely delays the start of the science applications.

These always cause the slow-down when they start up and try to use CPU and memory while Windows is still starting up and using the CPU and memory as well. Even I see those slow-downs on my 4 core PC, when I allow BOINC to start at Windows start.

Although cc_config.xml is read very early in the start-up of BOINC, there are no flags and options in it that stop or delay BOINC from starting up. Only externally started options could delay start BOINC. Like the sleep command used in a script on Linux.

Here is a cumulative answer to a number of posts.

This has nothing to do with timing. I can restart the client hours after booting and still the same issue. The system is all local, no fast user switching, not a VM, however I have VirtualBox installed for different purpose than running BOINC. No malware, the system is clean as a whistle. I have Symantec Endpoint Protection as my AV and also Malwarebytes Anti-Malware running constantly. I have tons of applications installed, including optimizer - TuneUp Utilities. So far everything is working fine, except BOINC (GPU issues), Nero Burning ROM (was crashing in ntdll.dll when certain actions were taken) and MiMedia (only certain partitions could be monitored).

This is not a hardware (dust, heat, KVM, etc.), but a software issue. I can reinstall the same driver on the top of the running one (without previously uninstalling the active driver) and that FIXES the issue until next reboot. After a reboot the GPU detection issue comes back. The driver files are still there unchanged, so it seems like a configuration issue. But what configuration is modified during a reboot?

I created cc_config.xml by copying and pasting the content and I started getting the message "Missing start tag in cc_config.xml". It took me a while to notice that the tag name was misspelled in the post (<cc_confgi>). After fixing this things started working better.

I reistalled the driver and before rebooting this is somewhat shortened content of the log file, however containing all the relevant stuff.

I'm puzzled.

Here too. Now, before I roll into bed:
Can you check for me if the Catalyst Control Center is still running? (Task Manager->Processes, there should be a CCC.exe visible)
Can you open the control center? (Start_>All Programs->AMD Catalyst Control Center->AMD Catalyst Control Center)
-> What does it say for "My VGA Displays->Properties (VGA Display)"?
-> What does it say for "Information->Software"?

Can you please install GPU Caps Viewer?
-> Going to the OpenGL tab, is your videocard recognized?
--> Can you run any of the OpenGL demos?
-> Going to the OpenCL tab, do you have the choice (drop-down menu) to choose your GPU?
---> If you do, is it recognized correctly?
---> Can you run any of the OpenCL demos on the GPU?

Edit1: You have installed your motherboard chipset drivers, right?
Edit2: In Windows Event Viewer, are there any messages about missing or corrupt drivers?
- Do you have enough swap space free for Windows?
- To automate the answers for the above questions, please download MiniToolBox , save it to your desktop and run it.

Check the following check boxes:
List last 10 Event Viewer log
List Installed Programs
List Users, Partitions and Memory size.

Click Go and paste the content into your next post.

You see, the symptoms you listed sound very much like some malware running. I was hoping that you would get a second or third opinion on that matter. You also didn't say anything about the various logs. Didn't they contain anything interesting or did you just forgot to look into them?

As for the drivers working after install but not after next reboot. I'm guessing the installer loads and configures all the necessary drivers while it does it's work. At some point later some other program goes and removes or overwrites some configuration information and then after the next reboot drivers don't get loaded properly.

Here's some excerpts from Wikipedia page for TuneUp Utilities:
disabling unnecessary visual effects and disabling or removing unused Windows services and programs.

unloads programs from memory and prevents their further automatic execution

And of course it has all the registry cleaners and everything.

Now I admit I have a very bad prejudice against software like this but would you be willing to uninstall it to make sure it isn't causing troubles here? Maybe Symantec as well.
