Message 6563 - Posted: 24 Nov 2008, 13:16:39 UTC - in response to Message 6562.  

This is the output from the WU:
<core_client_version>6.2.12</core_client_version>
<![CDATA[
<message>
process exited with code 22 (0x16, -234)
</message>
<stderr_txt>
execv: No such file or directory

</stderr_txt>
]]>

It seems your app_info.xml has an error with the file name of the executable.

Absolutely the same on my box.
EDIT: Also Ubuntu 8.10 and the same BOINC client hickop is using.
EDIT 2: I had a look at the filename and name in the app_info.xml... afaics, they are completely identical.

If you have downloaded the MilkyWay test application yourself and use the Boinc from the repositories. Then for the milkyway_0.2_x86_64-pc-linux-gnu application you may have to go Properties > Permissions tab > Ownership. Set User: boinc and set Group: boinc.

I think that's right, not sure because I forget things.

I can't try the test myself because I can't open the Projects folder. I've mucked something up and I get "Could not start process. Cannot talk to Klauncher: The name org.kde.klauncher was not provided by any .service files." No worries, I'll work it out or reinstall Kubuntu 8.04, 8.10 with KDE 4 is proving to be too buggy for me yet.

Not sure about the whole graphical "permissions tab" thing, but I figured it was equivalent to chown-ing all the files in the milkyway folder to user boinc group boinc and did just that. In my case I also needed to make the milkyway app executable (chmod u+x filename) in order for everything to work, but now, finally, all seems well. Thanks to everyone who came up with advice. I'll get back on the results soon.

Workunits validate okay, but they don't seem to be much longer than the last version on my box (around 9 minutes compared to a bit more than 7 on average), is that intended?
Anyway, a big improvement compared to the previus app: This one seems to be running stable on my system (only one which did that before was Milksop's, both Cruncher's and the old official app produced signal 11 for all WUs).

Message 6793 - Posted: 26 Nov 2008, 19:28:22 UTC

Question: Is the Linux (64bit) client too slow?
I'm asking because the test WUs with version 0.4 are much slower on my Linux 64bit quad (~21 minutes) than on my Windows XP 64bit lappy (~12-13 minutes).
Both systems are running with 2.4 Ghz so the difference shouldn't be that much I guess.
Lovely greetings, Cori

Linux manages power differently from Windows, running the low-priority BOINC applications at the slowest CPU frequency available (typically 1GHz). See this for more details.

I was looking for powersave options but I can't find them.
I'm a Linux noob so I need "step by step" instructions. *grin*

PS. The Quad is running under Xubuntu 8.10 64-bit.

"test 25"-WUs seem to be a bit bigger than the old ones, typically around 18 minutes on my box which is about 2.5 times the size of the "old" WUs.

Don't know if it's the 'right' way - but that did it for me:

/etc/default/powernowd

change
OPTIONS="-q"
into
OPTIONS="-n"

From the link above:
However, Linux can be told to not ignore low-priority processes by setting the option POWERSAVED_CONSIDER_NICE to "yes" in /etc/powersave.conf (or in a similar file, depending on the distro). This is a better approach than disabling power management forthright.

Ha, I found the file and after a little trick I was able to edit it!! Yippieh! :-)))

And many thanks to both of you - for me Linux is quite hard sometimes... plus the language mixtures (English/German) are making it even more difficult so I am always thankful for advice.


EDIT Someone else at my team forum suggested the gnome applets where I can set the system to "performance" which means that the cpu clock will not be lowered. Is this similar to the powernowd thingy?


EDIT 2 Something must have been the right trick because the cpu time for my WUs has dropped from ~21 minutes to ~ 14 minutes! YAY! :-)

Depends...
It works when you are logged in - if you log out, the applet is off too and your Ghz go down.

Ahh, good to know! :-) THX again.

So I will watch the situation carefully and if neccessary I can start the applet again.
The "powernowd option" is at least set to "-n" now. I am impressed by the speedup of my Wus - they're about 30% faster now.
