What Darrell didn't mention is that he is arguing that leaving a CPU core free to feed a GPU for maximum performance isn't necessary, ...

In fact he frees a core, one core per 5 GPU tasks (per his app_config.xml)

Do they run as 'High priority'?

If so BOINC just thinks they will not finish in time.
After a while of running one task BOINC see it progresses well and will finish in time.
So starts next task it think is in danger to miss the deadline.

Still can't get any gpu work.

The server keeps info for every app you run:
http://setiathome.berkeley.edu/host_app_versions.php?hostid=7304674

e.g.
SETI@home v7 (anonymous platform, ATI GPU)
Max tasks per day 1
Consecutive valid tasks 0

It takes a day I think for 'Max tasks per day' to be reset to 100 (?)
Every successfully done task (validated) multiplies by 2 the 'Max tasks per day'
2 4 8 16 32 64 (so you need a few good tasks to up the Max)

See my:
http://setiathome.berkeley.edu/host_app_versions.php?hostid=4832843


Then I went to gpu's with astropulse and that worked, but then I thought I didn't want to use up an entire cpu thread with the astropulse wu like you had in your sample app_config so I changed over to using the gpu's for v7

Wrong
Both AstroPulse and MultiBeam SETI@home v7 on ATI AMD "use up an entire cpu thread"

This is true when you use:
'new' Windows (>Windows XP) + 'new' ATI AMD drivers (>Catalyst 12.4 ?) + 'old' (current) ATI AMD apps
This (will) change with newer ATI AMD apps

(I don't need a free core because I use Windows XP + Catalyst 11.12)

Yesterday I tested (not in BOINC but in benchmark) the new (beta?):
AP6_win_x86_SSE2_OpenCL_ATI_r2180 but it fail on my system

I sent a PM to Raistmer with the log:
(still no answer, he must be busy or on vacation ;) )


Error in ap oclFFT_1: -34
ERROR: OpenCL kernel/call 'clFFT_ExecuteInterleaved_ap' call failed (-34) in file ..\..\ap_science.cpp near line 2653.

(the AstroPulse_OpenCL_ATI_ReadMe.txt do not say what AMD-APP version is needed or I can't see it)


AP6_win_x86_SSE2_OpenCL_ATI_r1843 works OK

(the error is near the end of log)


P.S.
You probably are in the impression that SETI@home v7 do not need a free core because CUDA apps on NVIDIA do not need it

26) Questions and Answers : GPU applications : What video programs do you have ot install to allow Seti to use the gpu? (Message 1542793)
Posted 12 days ago by Profile BilBg
One system keeps re-installing the HD Audio drivers

Yes, Windows do that
If you don't like this you may try to disable the device (HD Audio on the video card) in Device Manager


So apparently as long as you have the basic gpu device driver in place Seti will happily use your gpu.

I don't know what you consider as "basic gpu device driver" but:
- on NVIDIA you need CUDA and OpenCL drivers
- on ATI AMD you need OpenCL drivers

(I don't know how it is on newer driver packages, in the past the ('custom', 'advanced') selection to install CUDA and/or OpenCL is separate from 'Video driver')

Posted 12 days ago by Profile BilBg
Brook+ app is slow, it is named also as Hybrid as it do only ~ 20% of computing on the GPU and the rest 80% on the CPU (so since you have OpenCL GPU no point to use Hybrid AP)

What you can do safely - edit app_config.xml to run only one AstroPulse task (and the 2 tasks will be finished one after another).
(better exit BOINC, edit, start BOINC)

This APU is too weak to run 2 - that is the reason for so long running time (the 2 apps/tasks fight for GPU/RAM).

I am having trouble reestablishing myself with lunatics.

What did you do (1, 2, 3, ...) so far?

Some errors seem to be server or network related.
The computer need restart
(I think there were video driver crash - those AstroPulse tasks that end in seconds with strange infinity values 'Single pulse: peak_power=1.#IO;')

None are necessary for SETI@home
You can search on Google what they are.

I think:
3D vision - for 3D glasses and monitors

GeForce Experience
http://www.geforce.com/geforce-experience

HD Audio driver - to send Audio to TV via HDMI

PhysX - some games (Switchball) and demos (FluidMark) need it


I don't think they consume any noticeable CPU/GPU/RAM while not in use (but you may check the list of processes to see in your case)

Any ideas?

For low-end GPUs (APU, GT210) - do not tweak, use defaults
Run one task/GPU with default settings

What you see posted for GTX660 will not work on GT210 (what works for Ferrari will hardly work on Oldsmobile)


P.S.
No need to search or post the docs - all are in Lunatics' Installers

* Get the Installer:
http://setiathome.berkeley.edu/forum_thread.php?id=71867&postid=1375943#1375943

http://mikesworldnet.de/download.html

* Get 7-Zip
http://www.7-zip.org/


Use 7-Zip to unpack all in the Installer or only the docs:
...\Lunatics_Win32_v0.41_setup.exe\$_OUTDIR\docs\

Newer versions of the docs are found in files like (from mikesworldnet.de):
MB7_win_x86_SSE_OpenCL_ATi_HD5_r2170.7z
AP6_win_x86_SSE2_OpenCL_ATI_r2180.7z

For the TThrottle problem maybe you have to contact the author:
http://setiathome.berkeley.edu/show_user.php?userid=8906489

He probably will want to see the info from Logging tab with Debug checked


Lunatics:
Stock GPU apps are (almost) identical these days to the optimized (= lab accepted to use the Lunatics as stock)
- see my post with screenshots:
http://setiathome.berkeley.edu/forum_thread.php?id=75115&postid=1541308#1541308

Unstable? No

Improvement:
- CPU apps are faster (150-200%)
- you can choose which exactly apps to run:
    e.g. on CPU I run only MultiBeam (SETI@home v7) SSE2
    on ATI AMD GPU I run only AstroPulse (the most effective use of ATI)
- you may install newer Lunatics versions (manually, or wait for the next installer) without waiting for the lab for years to update the stock apps
(e.g. newer ATI AMD apps do not need a free CPU core per every task (I think 1 free CPU core is enough for many running GPU tasks))

Downsides:
Apps are not auto-updated (in fact I see this as an Improvement ;) )


P.S.
Is this "another gpu temp pgm" Open Hardware Monitor?

At what point do you consider a card is being overclocked over 400 or over 650?

Of course over 650


TThrottle only show one of my two gpu temps. Why?

Which graph?
Check 'Logging' tab in Debug mode
What is shown by SIV ?


My cpu's show a range in the low sixties. What temp is considered to high?

Depend on the CPU
For your Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
http://ark.intel.com/products/37147/Intel-Core-i7-920-Processor-8M-Cache-2_66-GHz-4_80-GTs-Intel-QPI

TCASE 67.9°C

http://www.cpu-world.com/CPUs/Core_i7/Intel-Core%20i7-920%20AT80601000741AA%20(BX80601920%20-%20BXC80601920).html

Maximum operating temperature 67.9°C

This is the Maximum operating temperature as measured on the center-top of the CPU case/package (where heatsink sits)

You may see 3 different CPU temperature measurement sensors/readings (not all are available in every case):
- 'core' (internal CPU sensors - 1 per core)
- 'package' (internal CPU sensor - 1 per CPU chip, somewhere in the silicon of the chip)
- 'CPU' (external sensor on the motherboard under the CPU - SIV can read and show these at the rightmost + real CPU voltage and fan speed)

(not every program names the sensors/readings the same, there is no standard)


To understand how Intel CPU sensors work read all my posts here:

I wonder if creating an app_info.xml file for the stock CUDA apps ...

Stock CUDA apps are identical these days to the optimized (that are inside Lunatics_Win??_v0.41_setup.exe)
(the .exe files differ in filenames and size - the stock is UPX compressed)

Right-Click your Stock CUDA apps .exe -> Properties ...

Dream on

Radeon X1000 Series is 3 generations older than what may (just may) work for SETI@home (Radeon HD 4000 Series)
And even Radeon HD 4000 is old (for driver support)

Edit:
But if you get (the post is not clear for me) some model equivalent to Radeon HD 4850 it may work (I think with 'legacy' drivers)

I discovered two settings in the bios that needed to be adjusted.

I wonder which BIOS settings that may be?

Ok, I think, maybe, I'm not sure..., I see a connection...

Connection?
You mean between Krisiya and SETI? Krisiya and aliens? ...

I wanted to post something for 1 April
And I wanted to present Krisiya to this community in some way
Then I combined the 2-in-1 (maybe in a peculiar way)

So probably there is no connection ... but who knows for sure ;)

Probably you mean "When I press Reset button in MSI Afterburner my system crashes"

System crash is always scary, so only in case you want to continue:

0) what MHz are shown by MSI Afterburner (in left and right) just after you started it after a reboot?

1) Try different version of MSI Afterburner

2) see that no other (monitoring) tool (e.g. from XFX or GPU-Z) that accesses GPU runs (they may conflict) (best if you exit all other programs that can be exited)

3) do the changes on idle GPU (right graph in MSI Afterburner will show low MHz)

4) Uncheck Synchronize ... here (and choose which GPU to tweak):
(I don't have 2 GPUs and am unsure how it will look and work)
