At first I thought I was having either video hardware or software problems but quickly narrowed it down to astropulse being the culprit.

It still doesn't cancel "software problems". You software config somehow differs from those who running AP successfully. So in some sense you really have software problems.
What driver do you use?

AMD Radeon HD 6570 ...

I use the same GPU (in ASUS HD6570 1GB DDR3 - ASUS EAH6570/DI/1GD3(LP))
and have no problems with both AstroPulse and SETI@home Enhanced tasks run on my ATI

Here are my AstroPulse v6 tasks:
http://setiathome.berkeley.edu/results.php?hostid=4832843&offset=0&show_names=1&state=2&appid=12

Application details for host 4832843
http://setiathome.berkeley.edu/host_app_versions.php?hostid=4832843
"
AstroPulse v6 (anonymous platform, ATI GPU)
Number of tasks completed 165
Max tasks per day 351
Number of tasks today 0
Consecutive valid tasks 235
"

My ATI runs at about 50°C (85-95% GPU load) during task run:




Your ATI also produces Valid AstroPulse v6 tasks:
http://setiathome.berkeley.edu/results.php?hostid=5868605&offset=0&show_names=0&state=3&appid=12

So I wonder how often the driver restarts?
(for me it happened only a few times in the last months if I try to run some very old games and forget to exit BOINC beforehand)

You have many restarts of the app (search for ### Restart) which may cause the problem:
http://setiathome.berkeley.edu/result.php?resultid=2609731911

Probably the restarts are because of 25% set for:
Suspend work when non-BOINC CPU usage is above XX%
http://setiathome.berkeley.edu/prefs.php?subset=global

Try to set this to 0 (zero)
(I and most people here prefer to set this to 0)

(the local setting is "While processor usage is less than [ 0 ] percent (0 means no restriction)")

I have been having problems lately with GPU processing. AstroPulse v6 6.04 (ATI_opencl_100) has been causing error messages about my AMD video driver not responding and a restart being successful. It does this about every few minutes (all input locks up and the screen goes blank then slowly comes back. I am running 3 monitors but not displaying the SETI processing graph on any screen. Usually it only involves 2 monitors (connected to the graphics card - the other is connected via USB). Also the elapsed time resets to zero during these episodes. The other thing is that I do not have my local preferences set to use the GPU and Boinc is running one more task than my local preferences allow. It only does this when the above mentioned astropulse program is available. I will revisit my web specified options to see if I can turn off using the GPU. My video card is an AMD Radeon HD 6570. At first I thought I was having either video hardware or software problems but quickly narrowed it down to astropulse being the culprit.


Huhu
3 monitors are operating on the graph? There still any resources for GPU Boinc projects are available? If the calculation is interrupted 100 times, it makes no sense and there are errors. Then turn off the GPU-work for Boinc.

@Mike

Disable GPU usage in Boinc

Create cc_config.xml and add it to c:\ProgramData\Boinc

<cc_config>
<options>
<no_gpus>1</no_gpus>
</options>
</cc_config>

Boinc restart.

Usually it only involves 2 monitors (connected to the graphics card - the other is connected via USB).

How do you do that, the connection through USB? Are you sure that's not a HDMI connection?

Which one is it?
This is a HDMI connection. This is a USB connection.

I am not aware of any monitor maker using USB as an optional connection. Most all use VGA, DVI-X and HDMI. Some still have S-Video as well.
VGA. DVI. S-Video.

Yep, some do have USB connections, but those are just a hub, they don't actually take input from a videocard to then show on the monitor. It's just that you can connect a USB cable from the PC to the monitor, and have your keyboard and mouse connect there.

There have been a few USB connected video devices around for laptops, but they were never particulalry successfull.
Very low performance devices the ones i'd seen reviewed.

OK, I see the USB to VGA converter now, but it doesn't seem like Mike has a laptop but a desktop instead (no M in his i5's description).

And even if you want to go spend 80 euros on a USB to VGA converter for a desktop computer, you're better off buying a new or secondary videocard. There's a HD6670 1GB I can get for €59,90, while an Nvidia GT630 4GB goes for €74,95.

Think that we disrupted this thread enough now? ;-)

Message 1290041 - Posted: 1 Oct 2012, 13:53:21 UTC

Thanks all for the various postings. I will examine them more closely as time permits. Just to clear up a few things:
* My USB connection to monitor 3 is via an inline DVI to USB adapter. Also that monitor is oriented in picture mode while the other two run in landscape mode. while connected to USB the performance is acceptable because I only run limited apps on it (MS Word, Win Explorer etc.) that are not graphics intensive.
* I was NOT displaying the SETI processing graph at the time. In fact it was still doing it when I sat and watched the screen. I suspect one specific piece of work caused the problem as I had done other SETI work using the GPU. I finally aborted that piece of work when I let it process for several hours and the "To Completion" time always reset to the same value when it recovered. Now that I have shut off GPU processing the problem is gone yet it is running the same astropulse application for new work.

Further changes coming:
*when the problem first started I preemptively ordered a new video card (I live far out in the boondocks and ordering by mail takes time). I decided to let that new video card come because, while it is the same card, there are two important differences. That is it has 2GB instead of 1GB and 3 video outputs instead of the current two. This will let me get rid of the DVI to USB adapter.

After this card is in and running I will open it up again to GPU processing and see if that fixes the problem (although I suspect it might not).

FYI: I have always been able to run games while BOINC was running the various projects I have selected with no noticeable problems (another hint this is tied to that one piece of work). I am hoping that extra 1GB of video memory will take care of this.

Various GPU-based BOINC projects or CPU ones?
We speak about app running on GPU. performing computations on GPU, not only showing some pictures on display as screen saver...
So please be more specific. What GPU BOINC apps you already ran successfully in current config?

Astropulse tasks have been failing on my computer too since I installed Lunatics. They go "Error" at the end of the computation.

My solution : say to the server that I don't want Astropulse tasks. After all, it has enough to do with regular tasks, and since there are only a few of them, someone else will surely process them shortly.

Sorry for that omission , the app was SETI astropulse with GPU turned on

The name is Raistmer, he is the main developer of this "AstroPulse applications for GPUs"


the app was SETI astropulse with GPU turned on

By "GPU turned on" you probably mean?:
Use ATI GPU yes
http://setiathome.berkeley.edu/prefs.php?subset=project

Even if "GPU turned on" this does Not mean that the AstroPulse task was run on GPU
(and if that happened before 8 Aug 2012 then it for sure was computed on CPU)

Before making conclusions you have to be sure that the task was sent for your GPU
(You see "Running (0.XX CPUs + 1 ATI)" in BOINC Manager and you see "AstroPulse v6 v6.04 (ati_opencl_100)" on the web)

Message 1294481 - Posted: 12 Oct 2012, 23:42:16 UTC

Just wondering why their is a lack of astropulse work. Seems all the splitters have stopped running.

(1). Does that mean there is no work for them to?
(2). There is some longish standing problem preventing them from running?
(3). For a completeness perhaps a combination of the 2 above :)

From the same raw data much less AP work can be generated then MB one so we wait when last splitted MB will finish to alow next raw data bunch to be splitted for AP too.

my apologies for my lack of basic skills: i cannot figure out how to get from my seti + astorpulse applications to any of those other projects that you listed in your table. If you respond with an answer(s), please be quite specific as I am so far below you in skills and knowledge that I will no doubt otherwise be quite lost.
Thank you

Rephrase your question, "i cannot figure out" ;) what you ask.
What "table" and what "other projects" are you talking about?

your BOINC Stats table has a number of different applicatons of BOINC. I am currently getting SETI and Astrop jobs, but none other. Is there a way to "sign up" for other BOINC jobs? If so, where and/or how? Thank you.

In BOINCmanager, change to Advanced View (in Tools menu).
Then Tools -> Add project...

Note that each project is a separate entity. As Ivan stated, if you use the Add Project wizard, it will show you a list of available projects. When signing up for each project, make sure to select that you are a new user to that project, and if you want all the stats to show across projects, make sure to use the same email address for every project.
