1) Message boards : Number crunching : Linux: any chance to let CPU in lowest power state? (Message 1588006)
Posted 7 days ago by Profile Dentaku
@HAL9000: nope, I already have a freuency selector, but don't want to change this all the time manually. I also don't want all-or-nothing. Instead I just want BOINC to keep the power state in the lowest setting.

@ausymark: that's not true: if I set set the freuqncy to "powersave" (in my case 1.7 Ghz which is the lowest selectable frquebcy) the work units get finsihed much faster than the max 5% CPU usage I set in the BOINC client! I found 5% is the maximum to let my computer "warm" and not hot. With the minimum power state of 1.7 GHz, the computer does get even colder than 5% of the time at full 3.7 GHz.

The problem is, that I still want to power state in "on demand", so that all my other Apps get the full frequency power of the CPU. I want BOINC running all the time in the background - but without letting the CPU using higher frequency but stay in it's lowest "on demand" frequency. When I start another app, this should behave normally, meaning: power state should be able to increase if these apps demand more CPU power.

So far, I just read about Linux system configuration to force all "nice" threads to not increase the CPU frequency. But this change would force _all_ nice threads to not use the full CPU power.

The only workaround I use so far is, to manually set the power state to "powersave", start BOINC and stay with the lowest freuqncy for the other Apps I'm running during computer usage. If I want full CPU power, I exit BOINC and switch back to "on demand". Of course, I don't want to do this all the time.
2) Message boards : Number crunching : turn memory clock lower to decrease temp in an amd gpu? (Message 1588000)
Posted 7 days ago by Profile Dentaku
I not only want to decrease temperature but also like to keep the CPU frequency down. I'm running BOINC on linux here on an AMD APU (7850K). If I let run BOINC 100% the computer get's very hot and the CPU is always 100% usage at full frequency.

When I set 5% CPU usage in BOINC client, it doesn't really use permantly 5%. Instead it uses 100% CPU at 5% of the time. This leads to 100% CPU usage in full frequency (3.7 GHz) every 20 seconds. That's not what I want. I would like BOINC to always run but keep my AMD CPU in the lowest Cool&Quiet frequency. Running Ubuntu, I can see with the frequency indicator that Cool&Quiet is running very well ... until BOINC kicks in and pushes it to the maximum.

How can I run BOINC without letting it increase the CPU frequency?

Well, the BOINC client can be configured to use only x % CPU. But this is a fake software workaround as it just activates the client x % of time leading to 100-x % time no CPU usage and x % time 100% CPU usage. And the 100% CPU usage means 100% GHz when using "demand" setting, i.e. dynamic GHz setting.

I read about Linux configuration to change some system file to stay in low power (low GHz) mode for "nice" processes. But don't want to change a system file and I don't want to change such a system setting that is affecting _all_ such processes (not only BOINC processes).

Is there another way to have BOINC running but keep the CPU in low GHZ AMD power setting (Cool & Quiet) all the time?

Any experience of Linux users with latest Catalyst driver?

Others play 3rd person shooter, I crunch SETI@home work units. Still waiting for the first signals that proof that we are not wrong.
7) Message boards : Number crunching : Optimized app available for CUDA enhanced version coming? (Message 848387)
Posted 2 Jan 2009 by Profile Dentaku
Okay, this was confusing: the SETI@home CUDA page (http://setiathome.berkeley.edu/cuda.php) says:

"CUDA apps are supported only on Windows and Linux; Mac OS X support is coming soon."

and the FAQ (http://setiathome.berkeley.edu/cuda_faq.php) says:

"Releases for MacOS X and Linux are planned in the near future."

Thanks for the hint! SO I have to wait for Linux CUDA support ...

Oh yes:

No, I don't have this file - I'm running Linux (Ubuntu 8.10, 64 Bit).

So, Linux is also supported. I wonder why I still get no CUDA work units on my Ubuntu 8.10 ...?

I just got a new graphics card that supports CUDA. BOINC is reporting "CUDA devices found". Coprozessor: GeForce 9400 GT (1). I finished all SETI WUs and now a new WU was downloaded: but no "CUDA" substring in the text ... just the same old "SETI@home ENhanced 5.28". WHat is wrong?

Since my Ubuntu upgrade from Feisty to Gutsy, all my BOINC tasks fail after some hours. The last SETI WU:

--------------------------------------
freeglut ERROR: Function <glutTimerFunc> called without first calling 'glutInit'.

13) Message boards : Number crunching : How many BOINC projects have a screen saver? (Message 660259)
Posted 15 Oct 2007 by Profile Dentaku
Project Beta Win32 Graphics Linux Graphics BBC Climate Yes ? CPDN CPDN Beta Yes Yes Einstein Pirates Yes Yes Laden Classical Yes ? LHC Yes ? MalariaControl Yes ? QHC Yes ? Rosetta Ralph Yes No Seasonal Attr. Yes Yes SETI Yes Yes Spinhenge Yes ? World Community Grid Yes ?



The answer for World Community Grid is yes/no as some applications of this project offer graphics on linux and some don't.

The answers to this question also need to state their system! On Linux, many BOINC projects don't offer graphics and/or a screensaver.
15) Message boards : Number crunching : 64 Bit - would it be worth it for SETI@Home tasks? (Message 659077)
Posted 13 Oct 2007 by Profile Dentaku
I have 64 BIt BOINC 5.10.21. And since yesterday, SETI updated itself to 5.28 "Multi-Beam". Is this a special 64 bit version of just the 32 bit version in a 64 bit "wrapper" (only recompiled)?

Posted 13 Oct 2007 by Profile Dentaku
Based on prefs - which are on all projects 100% cpu, 2 processors.
Some hours later I noticed that BOINC continued as expected: 2 tasks running. But it took several hours until the second task switched to running again. strange ... :-/

Last night I left my computer on also running boinc. this morning, only 1 task is running, and 3 other tasks are in state "waiting to run". ried pressing suspend + resume for those tasks, but they don't start. the messages window doesn't show any errors ... ?

Is it possible to switch off the tumbling when the graphics are displayed? I can stop it while holding the left mouse button, but I would prefer nombling at all.

I just noticed some different graphics today in a new work unit. It says "Multi-Beam" at the top left. What does it mean?

Me too - since 24 May 1999! :-)

When I upgraded from my old 900MHz Athlon to a new AMD X2 3800+ EE, my world position changed dramatically from falling behind to climbing up to almost the old days high positions. Now, it's declining again and I'm looking forward to the new quad core Phenoms ... then I will dedicate 3 cores to BOINC and 1 left for all the other stuff I do ... ;-]
