... but I'm not able to uncheck the correct box. Any ideas?

To be able to check/uncheck anything - use 'Edit preferences' at the bottom of page.

You can do it Locally from the BOINC ...

But mind this will 'freeze' the Preferences to Local (until you use [Clear] button):
23) Message boards : Number crunching : Intel® iGPU AP bench test run (e.g. @ J1900) (Message 1679922)
Posted 10 days ago by Profile BilBg
In ap_cmdline_win_x86_SSE2_OpenCL_Intel.txt: -cpu_lock -instances_per_device 1
in ap_cmdline_win_x86_SSE2_OpenCL_NV.txt: -cpu_lock -instances_per_device 3

The same result in Task-Manager:
1 Intel iGPU app at Core#0
1 NV GPU app at Core#0 and 1 NV GPU app at Core#1

I think Raistmer means -instances_per_device 3 for both apps

You can just set (for both apps) -instances_per_device 8
-instances_per_device don't control how many apps (.EXEs) are started
It only tells the already started apps (started by BOINC, or by (several) benchmark tests) to really 'work' (use the GPU to compute and not wait for it to become free)

Probably you set the web Computing preferences

What are the values for:
Store at least XX days of work
Store up to an additional XX days of work

But (as written at the top):
These settings apply to all computers using this account except:
* computers where you have set preferences locally using the BOINC Manager

Read the top 'Note' on: Local preferences
* Settings override the same preferences set on the project's web page preferences.

If you ever clicked [OK] in Local preferences - they are in effect.

(They ALL are in effect, not only the values you eventually changed.
And there is [Clear] button which deletes global_prefs_override.xml
If you decide to use [Clear] button - never use [OK] again to "close" the dialog, use [Cancel] or <Esc>

Which browser?
I guess there is some incompatibility with your browser or your extensions/add-ons
If "screen block" means tab or browser hangs - try to disable your extensions or use another browser.

The following tests are in:
Slimjet Browser Portable (Chromium 40.0.2214.93)

For me when I click on "I'm not a robot" there are 3 variants (which change from time to time)
pictures, text, or just the click 'solves' it:

That computer is on another account!
Computer 7535648 Owner KLiK

Compared to the account you're posting from here:
(E.g. Computer 7422247 Owner KLiK anything you do under this account won't affect that computer.

probably is sthg to do with BOINC-BAM & SETi@home accounts not being joined...

how to correct that? :/

SETi@home accounts can Not 'be joined' (can Not be merged)
Choose one of the accounts and use it for all computers.

Posted 13 days ago by Profile BilBg
Which tool & test task I must use for to let run SETI (MB) bench test run (simultaneously) on NV (GT730) GPU?

I think:

MBbench 2.10;sa=dlview;id=387

V7 MB test WUs 1 - WUs adapted for V7 testing (PG set);sa=dlview;id=296

For apps - maybe compare:

You posted this question in 'Android Version Checking' ~2 months ago:

If they don't answer there I don't think they will answer here (I doubt they look here)
I guess they will release it when they have time to focus on that app

Posted 14 days ago by Profile BilBg
BTW, it's possible to make a bench test run with AP app/task and SETI (MB) app/task simultaneously?

The same answer:
Maybe just run 2 bench tests simultaneously from 2 directories
(to load CPU you may run even more tests simultaneously or use BOINC to load CPU by 'mode noBS')

Posted 14 days ago by Profile BilBg
EDIT: BOINC say 'driver: 1.4.344' installed.
What does this mean, is this the laptop manufacturer driver 'v8.635.0.0 Rev. B'?

BOINC 'say' the CAL version

CAL 1.4.344 = Catalyst 9.7 = 2D Driver Ver 8.632.0.0000
so v8.635.0.0 should be about the same date 2009.07.xx

Test the new app with this driver before making the user to change drivers
- you know: old GPU 'feels' better with old driver

Prepare for the user benchmark package - ask him to run it and send you the results (the .txt file from ...\APbench\Testdatas\)

Your link for "Win7 x64 AMD GPU Driver" = Catalyst 14.12 will not work.

Last Catalyst for AMD Radeon HD 4000 Series / AMD Mobility Radeon HD 4000 Series seems to be:
Catalyst 13.9 (I don't know if it's good or not)

34) Message boards : Number crunching : NV GPU - AP bench test run (e.g. @ GT730) (Message 1678165)
Posted 14 days ago by Profile BilBg
What or how I need to adjust something, that the bench test run run on the NV GPU and not again on the Intel iGPU?

AP7_xxxxxxxxxx.exe --device 0
AP7_xxxxxxxxxx.exe --device 1
(just test which device # will fit)

The above lines may be used in BenchCfg.txt
or --device # may be added in APbench211.cmd to:
set ref_app_args=
set sci_app_args=

How can I adjust the bench test run, that 2 bench test tasks are running simultaneously on the GT730?

Maybe just run 2 bench tests simultaneously from 2 directories and use for both
-instances_per_device 2
35) Message boards : Number crunching : New Linux rootkit leverages GPUs to hide (Message 1675565)
Posted 17 days ago by Profile BilBg
I don't think this rootkit can travel from 'infected' GPU memory directly to another system's GPU memory.
It have to use the usual means of spreading (through CPU memory, disk/file, network) - e.g. by luring people to Download some file and run it.

So it's just a matter of adding signatures and/or heuristic to existing Antiviruses
(by normal means of signatures/modules update, no need for a new kind of Antivirus to detect just a normal file before it is run/at the moment it is written to disk)

But since Linux people don't think they need Antivirus ...

I also read this:
"Acquiring high-resolution time stamps":

The most funny part ;) for me was:
How do I determine and validate that QPC works on my machine?
     You don't need to perform such checks.

  Sounds like:
Stormtrooper: Let me see your identification.
Ben Obi-Wan Kenobi: [with a small wave of his hand] You don't need to see his identification.
Stormtrooper: We don't need to see his identification.
Ben Obi-Wan Kenobi: These aren't the droids you're looking for.

They also say:
Do I need to set the thread affinity to a single core to use QPC?
     No. ...

But the first user response at the end:
Is the performance counter monotonic (non-decreasing)?

Would be nice if the above was true, but it's not. I can't speak to the technical reasons why this happened in my application, but I found that in order to have monotonic behavior, the thread affinity had to be set. Specifically, the counter was monotonic on only a single CPU core, and affinity had to be set to deal with this. As I recall, this was in a Windows XP SP3 virtual machine running in VirtualBox. All four hyper-threaded cores on my Core i7 were available to the guest (i.e. 8 logical CPUs). Maybe the newer versions of Windows work around this; I don't know.

Many others have observed this behavior...

.NET Stopwatch class (based on QPC):

Note it can be proven by decompiling/examining .NET 2.0 to 4.0 sources to see that MSFT themselves added a hack to protect against returning negative durations in their stopwatch class (see my answer in link above). So you can't say "yes" that the QPC function is monotonic when the NETFX programmers themselves coded to protect against that, and lots of devs observe that it's not.

My 'bad tests' were on Windows 2000 (and didn't happen on the same machine under Windows 98) this may be related:

You have strange big numbers like in my tests:

Joe may be interested to see more tests (e.g. if you will see also strange big negative numbers):

I may guess "big negative numbers" are in fact "too big positive numbers"

OK, here example of your "big negative numbers":

And it results in:
"fpu_opt_ChirpData -79751928.307712 0.00000 choice"

There is also "very small negative number" which have to mean the counter was just 'a bit' over 2147483647

I am having problem with work units starting and then after days it is still at the same time and percentage done.
When I look at the graphics it shows choosing optimal functions

Read here:

This is a long existing problem with 'Optimal function choices' test on AMD CPUs
- sometimes the test hangs, sometimes not. On some systems it hangs a lot, on some - never/rarely
(long existing = years = don't expect fix of the stock apps soon as "Someone have to figure out why it happens on some systems before a fix is proposed")

The only real cure is using apps which don't do 'Optimal function choices' (and are faster):
Optimised Applications - Installer v0.43a

After about a week of this going ... I would rather have a fix than abort the work units.

No need to wait more than a few minutes - on your CPU 'choosing optimal functions' should finish in < 30 seconds.

And no need to abort -
just Suspend/Restart the task

(If you start using Optimised Applications there will be no need for Suspend/Restart as they will never hang)

But if you stay on stock/standard apps:
- You may need to do Suspend/Restart several times (it is unclear when the test passes and when it hangs).

Hang don't depend on task, it depend on (stock) app - so may happen for any CPU task.
This test is done before the app even looks at the task data.
But if the app goes past 'Optimal function choice' it will no more hang during computing
(unless the task is Restarted again - any Restart (e.g. from 77%, from any %) do again 'Optimal function choice')

Go for Optimised Applications and you are 'cured'
