If you have work in that folder I wouldnt delete it just move to someplace convenient then reinstall boinc and move the files back to where they were before.


and that's how I found that disk corruption was the problem. thanks to all.

The actual folder where the files are kept may be fouled up.

I would run a disk check and then delete the actual boinc data folder.

Then try the re-install.

The messages seems to indicate that it cant delete or rename the existing state file, and thats most likely a messed up directory structure.

and that was the problem and the fix! Great!

Alternatively, re-run the BOINC installer for your current version. When prompted, select 'Repair' mode.


did it twice. does not fix the problem. should i try the other suggestion w/permissions?

Boinc on Windows XP Pro is installed with default permissions (running as an unprivileged users, etc). After the latest Windows upgrade, permissions look broken and Boinc doesn't start anymore. Please help.

I wasn't quite clear -- if you have a Gnome based system, the setting is managed by Gnome and persists through reboots.

Post:
Some users running Seti on their notebooks observed that their CPU clock speed reduced to the lowest. This happens because, under some conditions, Linux does not consider 'nice' (aka low priority) processes as CPU load. This happens even if the notebook is plugged in the AC.

This is a great compromise for less heat+longevity of your notebook vs raw crunching power.

Note: this works only for newer versions of Linux.

cd /sys/devices/system/cpu/cpu0/cpufreq/ondemand
more ignore_nice_load

If this is set to 1, then your CPU speed will scale down when runnig Seti only.

If this is set to 0, then you CPU will run at full speed when running Seti.

You can change this value right there, but it won't persist through reboots.

How to change it for gnome-based systems:



Run
gconf-editor
go to /apps/gnome-power-manager/cpufreq
check box consider_nice.

Takes effect immediately.
11) Message boards : Number crunching : 64 Bit - would it be worth it for SETI@Home tasks? (Message 661154)
Posted 17 Oct 2007 by Profile michael37
Post:
I use Crunch3r's 64-bit Linux app and it performs slightly faster than 32-bit.

My biggest issue is support for 64-bit BOINC itself for my 64-bit systems. The only officially released 64-bit version 5.10 requires awfully new libraries which are not provided for RHEL3 and RHEL4. The latter one truly boggles my mind -- RHEL4 is only two years old and will be supported for years to come.

I can't seem to build BOINC either 'cause BOINC expects automake and other build tools are too old on RHEL4.

So, it's 32-bit BOINC client with app_info.xml and 64-bit applications...

A few days ago, it would post, but would not boot into the operating system. I took it apart, checked the CPU and found a crack on the substrate right next to the chip. I'd say it was definitely heat. I have not overclocked the chip, and I used a standard AMD cooler.


Ouch! Sounds like poor manufacturing (perhaps a bad batch). I still have an Athlon Classic running at 1.4GHz using a ceramic package that is working well 24/7.


Maybe :) I can't complain though, this CPU had been crunching Seti between 2002 and 2007.

Yo people, I just had one computer to go into "not asking for more work" because it ran into a couple of error workunits in a row.
Once that happens, the project goes dry for a day or so.

All workunits have "bad headers" -- and it is not my computer problem since these workunits had the same errors from all computers that had them.

Well, I just suffered my first serious hardware fault from the dreaded enemy after 8 years of running Seti. This computer had an Athlon XP 1800+ which was a fairly quick CPU back in 2002. It ran seti non-stop from the moment I put my desktop together.

R.I.P.

Luckily, I had an Athlon XP 2500+ lying around and not used =) So, I expect my RAC to go up now :)

I've done some searching and can't seem to find an optimized client that will run on my servers.

GenuineIntel
Intel(R) Xeon(R) CPU 5130 @ 2.00GHz [Family 6 Model 15 Stepping 6]

running:
Linux
2.6.18-36.el5xen

I've tried several clients from http://lunatics.at/ with no luck. Any help would be greatly appreciated!


Download applications from http://calbe.dw70.de/seti.html

Not enough info, just run "uname -a" to determine the architecture of your computer.

If it says i686, then you need 2.4L_Linux32_Intel_SSE3.tar.bz2

If it says x86_64, then you need 2.4L_Linux64_Intel_SSE3.tar.bz2
20) Message boards : Number crunching : 5.10.20 now recommended Boinc version (Message 639480)
Posted 12 Sep 2007 by Profile michael37
Post:

I have been running 5.10.8 on Linux (Slackware) for several months now. It's still listed as a development version but I've had no problems with it at all.


Is your Slackware 32-bit or 64-bit? I have tried 64-bit version on my 64-bit Fedora Core and experienced boinc aborts with nothing in the logs: just boinc process dies. I usually start boinc on Linux with flags "-daemon -allow_remote_gui_rpc".

Also, I can't run 5.10 64-bit on RHEL since it requires newer glibc libraries (GRRR RHEL4 is not even 3 years old and boinc already doesn't support it). I went back to 32-bit 5.8 boinc on those 64-bit machines and I use app_info.xml to run 64-bit Seti apps on these computers.
