And why don't you set BOINC to run apps Always?

Is there anything at all that can be done about the heat that SETI creates?

You may:
- use better cooling
- use TThrottle


It is the application that generates the heat and you are one of the programming gurus so fix it already!

There is nothing to "fix" - any optimized computing will heat the computing device (CPU/GPU/...)

Try to encode a video in AVC (x264 codec)
http://avidemux.sourceforge.net/

Try a 'heavy' game

Try Linpack
http://www.xtremesystems.org/forums/showthread.php?201670-LinX-A-simple-Linpack-interface

(all the above will heat)

I just noticed an unusual thing. I recently changed my setting to run 4 APs per GPU on the GTX 780 SC. I have 0.6 CPU per 0.25 GPU

Be careful with those values

3 GPUs * 4 tasks = 12 GPU tasks

12 * 0.6 = 7.2 = 7 cores

This means BOINC will need to see 7 cores as free/usable to start GPU tasks.
If you run also CPU tasks (from any project) or have 'On multiprocessors, use at most XX% of the processors' this may limit BOINC to less than 7 cores available to 'allocate' for GPU tasks.


But in this case the problem was "some exception" ;) :
ERROR: some exception inside long FFA, probably video-driver restart, restarting app...

Also, the tuning parameters from AP v7 won't be picked up, they need to be set separately.

Strange, I have one and the same file:
ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt

... that is "picked up" for both AP v6 and AP v7 - as per app_info.xml
<file_ref> <file_name>ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt</file_name> <open_name>ap_cmdline.txt</open_name> </file_ref>


P.S.
He probably installed the new Lunatics and need to look for his old ap_cmdline file in 'oldApp_backup'

add this

-use_sleep -unroll 12 -ffa_block 8192 -ffa_block_fetch 4096 -tune 1 64 4 1 -tune 2 64 4 1.

I wonder what will happen if the user copy the line as it is - with the dot at the end.
Will this be accepted by the app or ... all tasks will fail?

I will resist temptation and spend a few days studying before attempting to install.

The install is only committed on the 'last' page (when it asks for directory - defaults to the right place but you may change it to some 'test' directory)
No changes to BOINC/SETI@home are made before that (so you may exit it early safely)

When you install Lunatics, each "page" has different options for installation.

Here are the screenshots I made from the previous installer:

Salt + water = electrolyte = conductive
You have to find and dry it (e.g. by cotton-on-stick (is it the right word?))

If you can't find the drop - wait it to dry before switching ON
To test the dry time - make another drop outside the computer ;)

One obvious thing is wear a wrist strap to prevent static electricity from screwing up the electronics.

I just wear cotton, walk on socks and touch the wall and computer case before reaching to the computer insides.
Also in hot weather sweat from my face may drop on the electronics ;)

It seems to me: all the sockets on the power supply that have the same 'shape' are equivalent.
If you can plug a cable in it - it is in the right place ;)

I think there are two "4+4 CPU" cables in case the motherboard have 2 physical CPUs

http://www.corsair.com/en/rm-series-rm850-80-plus-gold-certified-power-supply

Have some info (e.g. what is "Corsair Link" (C-Link))
Have some PDFs and FAQ

There is this (interesting for me) info in CORSAIR-PSU-MANUAL.pdf
"Corsair’s GS, TX, TX-M, RM, HX, AX (not including AX1200) and AXi all feature a Zero RPM fan mode.
At low loads, the intake fan will not spin, allowing the power supply to operate in absolute silence."

I completed a 40 second AstroPulse v7 v7.00 this morning, while I was drinking my coffee:)

http://setiathome.berkeley.edu/results.php?hostid=7271690&offset=0&show_names=0&state=0&appid=20

Are you sure you didn't slip your CPU some of your coffee? :)
I am going to guess that it is over 90% blanked. Once your wingmate returns their result you can see the blanking.


Its 100% blanked and aborted too much RFI.

Ah. I was just looking for the "percent blanked:" line. I didn't notice the "In ap_remove_radar.cpp: get_indices_to_randomize: good data chunks < 1. Blanking too much RFI?"

Look again ;)

The second task show "percent blanked: 7.45" and is 'Completed and validated' on its own! ???
(the first 40 s task is still 'Completed, waiting for validation')

It's a corsair 850 watt

It helps if you give links, I forgot the exact model

In my posts - only 2 that have "1000 MHz" (but none is about "clock of other brands")

(I think you mean Glenn savill)

The stock clocks (MHz) for AMD Radeon HD 6570 are (GPU/RAM) 650/900 MHz
http://www.amd.com/en-gb/products/graphics/desktop/6000/6570#2
(this official page is too dark - use Ctrl+A to 'see in the dark')

My ASUS EAH6570/DI/1GD3(LP) have the same standard clocks: 650/900 MHz
I run it at 800/1050 MHz (max allowed by MSI Afterburner on my card)

... so its really based on numbers and popularity of that card.

That is not right

The person to listen about BOINC internals is Josef W. Segur

// "best-performing" is defined as minimizing the average of
//
// elapsed_time(J)/rsc_fpops_est(J)
// over completed jobs J currently in the DB


"Best GPU" = Min (Run-time/FLOP-count-estimate)

Seems to be calculated only for:
- tasks that run > 100 seconds
- tasks sent in the last 30 days
- only max 500 tasks for given GPU model are included in the average

Do not depend on "numbers and popularity of that card"
Only if really low number of some GPU model is used here (e.g. < 10) this may be the reason of more fluctuating
