21) Message boards : Number crunching : No CPU work, only CUDA, won't even request (Message 925573)
Posted 1807 days ago by Profile Harri Liljeroos
Hi,
I just run into a situation where boinc does not request any work for my CPU, only for GPU. CPU has nothing to crunch at the moment.

I'm attached to 4 projects with following shares: CPDN 30, Einstein 25, LHC 150 and SETI 100. CPDN and Einstein are NNT (Einstein is down anyway), LHC doesn't have anything to crunch so that leaves only SETI. But CPU is just idling. This system has previously been doing both GPU and CPU WUs (last 6.03 CPU WU finished yesterday). Since then CPU was doing Einstein and now those are finished too (5 ready to report and 5 uploading).

Boinc is 6.6.36 (WinVista 32), opti apps SSSE3 (Lunatics 0.2 Unified Installer w. VLARnokill), CPU=Q9400, GPU=9800GT (driver 190.38, CUDA 2.3). Preferences are set to accept all kinds of work and all types are in my app_info.xml

I switched on the log_flag for work_fetch_debug and here is output for that:

Can somebody interpret why Boinc is not requesting any work for the CPU?
22) Message boards : Number crunching : Anyone else have issues with the new Nvidia driver? (Message 924032)
Posted 1814 days ago by Profile Harri Liljeroos
I have noticed that with the 190.38 driver version (Vista 32) my 9800 GT does not use DVI-D anymore when showing the desktop (1600x1200), it uses DVI-A. Previous driver I used was 182.50 and it did use DVI-D which gives a slightly better picture. I remember having similar issue with some earlier update as well. When I restart the computer monitor states that during post it is actually using DVI-D 1600x1200 but when the graphics kick in the signal changes to DVI-A 1600x1200.

The card is from MSI and so was the driver 182.50 now the driver is directly from Nvidia. Could this be the reason?
23) Message boards : Number crunching : Unable to stay logged in (Message 924028)
Posted 1814 days ago by Profile Harri Liljeroos
I've done a little more testing. The Firefox yesterday updated itself to 3.0.13 but that didn't change the behaviour. I have the front page of message boards bookmarked (managed with the Xmarks addon) and if I use this bookmark to go to the message boards front page and click from there one of the boards (like Number Crunching) the log in is somehow lost. If I navigate from Seti's homepage -> community -> message boards -> number crunching log in is not lost.

On one computer the message board front page even looks a little different (font size) depending on the way I go to that page, using bookmark or navigating from the homepage.

NEWS FLASH: While writing this I was doing some tests and noticed that my bookmark points to a different http-address than what I get when navigating. Bookmark: setiweb.ssl.berkeley.edu vs. navigating: setiathome.berkeley.edu

Both seem to have all the latest messages visible but the setiwaeb.ssl.berkeley.edu won't keep my log in alive. It seems I have to modify my bookmark.

Posted 1815 days ago by Profile Harri Liljeroos
The problem is back. I have now these message boards open in two tabs in Firefox. In this tab where I am writing this message I can see the yellow marks for unread messages. On the other tab clicking "Account" on top of page always gives me the log in screen (I have stay logged checked on that page) and after logging in I can see my hosts with other data (so the log in was OK) but the message boards won't show the yellow "unread messages" marker and clicking the "Account" gives me the log in screen again.

If I view a thread and click "post to thread" I get the log in screen again and after logging if I return directly to the message thread the yellow markers are there.

So does anybody have a glue what is going on? Does anybody have same problem? Firefox was yesterday updated to 3.0.12.

Indeed. I had the problem for about 10-15 minutes and then it was back to normal again. :)

Today I am no longer able to stay logged in here. This happens on all computers I've tried so far. Using Win XP and Win XP64 with Firefox and IE7.

Has something changed here on the web pages?

Edit: Now it is working again!
27) Questions and Answers : GPU applications : New version 6.6.31 not exiting? (Message 908327)
Posted 1864 days ago by Profile Harri Liljeroos
This works at least on 6.6.36:
- open a command prompt window and go to "\Program Files\BOINC\" directory
- there is an executable program boincmd.exe, run it with parameter --quit
- this should shutdown boinc and the science apps
28) Message boards : Number crunching : AstroPulse Ghost WUs !!! (Message 791978)
Posted 2181 days ago by Profile Harri Liljeroos
If you are using anonymous platform, how does the server know if you have all applications installed on you computer? Does it have any other way but to send AstroPulse WU's? Then BOINC could report back to server that applications were not found and mark the WU's in question rejected or something.

Internal Error 2753

http://boinc.berkeley.edu/dev/forum_thread.php?id=261



Thank you for the link. I removed Boinc using installer without deleting manually any files from Boinc folder. Then copied all executables and now everything seems to run OK and I didn't loose any WU's.

Thanks again!
30) Message boards : Number crunching : Unable to install Boinc 5.8.15 (Message 524044)
Posted 2704 days ago by Profile Harri Liljeroos
Hi,
I've been updating Boinc to my computers but on some of them without success. Out of six computers so far three has failed. OS (win2000, win xp) and previous versions of Boinc (5.4.11 and 5.3.12) vary on these hosts.

After I stopped boincmgr and boinc daemon I run the installation package (single user install) and everything seems to progress as planned but when installation routine tries to launch Boinc it gives error: Internal error 2753. boincmgr.exe

Manually starting Boinc starts the previous version like nothing new was ever installed. On two computers none of the executable files in Boinc folder has been changed, on one computer only boinc.exe was changed from 5.4.11 -> 5.8.15 but boincmgr.exe is still 5.4.11.

Rebooting and reinstalling (repair) does not make any difference. Removing Boinc completely may be next step but I am unwilling to do it just now as two of these host have about 2000 hours worth of unfinished workunits for CPDN.

On three computers updating went just fine (win2000,winXP, winXP x64 and Boinc 5.3.12).

Anybody have similar experinces or pointers how to solve this without removing Boinc first completely?

34) Message boards : Number crunching : Current download problem prohibits also other projects downloads (Message 457621)
Posted 2809 days ago by Profile Harri Liljeroos
It's my guess that his client has requested X seconds of work from seti and the order was filled, but just hasn't reached him yet, so the puter thinks it has X seconds on hand when infact it doesn't. The scheduler has already taken that into account and isn't requesting other work. Atleast, I think this is correct.

So when the download is finally completed, he would have X seconds on hand, and if the code was changed to see the non existent download and actually get work from elsewhere, then if the outage was short, the host would be overcommitted and risk missing deadlines.

I think that's what is happening. This is one rare situation when micro managing may be needed. As I mentioned, suspending seti for a minute allowed other projects to download some work and keep my hosts busy, at least for a while.

Posted 2809 days ago by Profile Harri Liljeroos
Hi,

for some curious reason, my hosts did not download new WU's from other projects although CPU's were already running idle. BoincView shows that there is a work buffer for sah even when download is not succesful.

I had to suspend sah to download new work from Einstein. This happened with Boinc 5.4.11 and 5.3.12 (truXoft). Update did not help.

37) Message boards : Number crunching : Calibrating Client v5.3.12.tx37 - fair credits in all projects (Message 236295)
Posted 3104 days ago by Profile Harri Liljeroos
Hi,
I started to use the version tx36 on one of my computers and I've had some new problem: I'm running on this computer SETI, LHC and CPDN and four times I've received error

2006-01-23 13:24:36 [SETI@home] Result 17se04aa.6145.25137.848566.1.59_2 exited with zero status but no 'finished' file
2006-01-23 13:24:06 [SETI@home] If this happens repeatedly you may need to reset the project.

Two times on SETI and two times on LHC. On one of the slots folders I found sterr.txt which said "no heatbeat from core client for 31 seconds".
I am running on this computer also a 3D simulation program which can take 99% of CPU time for hours at a time. I believe this might be the reason for this error. Anyway I have run several previous versions of Boinc clients (standard and optimized but not calibrating) without seeing this problem before although I have been running the 3D simulation with them also.

So I think that this version is somehow more sensitive to other software using a lot of CPU power.

Nice work!
The Last WU Received column is showing 1970-01-01 01:00:00 UTC on all my computers.

hmm, ok will look into it, but I'm on my way to set off for the weekend. Will be back on Monday.


OK, have a nice weekend.

Maybe you could add the explanations for different numbers on #wu's column? At least I don't usually remember their meaning.

Harri Liljeroos

There is already a description available. Just hover your mousecursor over the column header. :-)

Andy

Missed that one. Thanks for pointing that out.
