1) Message boards : Questions and problems : Can't get Boinc running after restoring a backup. (Message 40698) Posted 17 Oct 2011 by dividedbymyself Post: Yes, I should have thought about that because I actually knew that. But I've just finished. Many of them are in the 'Choose a project' panel, so they're quick to attach. The rest is just a google, a couple of clicks and a copy&paste away. Thanks Gundolf Jahn.
2) Message boards : Questions and problems : Can't get Boinc running after restoring a backup. (Message 40696) Posted 17 Oct 2011 by dividedbymyself Post: I've always used the same procedure on Windows, it works there as far as I can remember. I just tried to copy before installing several times, with and without overwriting already existing files and with changing the group and permissions to read&write. All without result. The client stops by itself and the manager can't of course connect to it. Maybe I better manually attach to the projects again. I'll lose maybe 2 days of work, I can live with that. The hardest part is to find all the url's again. Most of the projects don't have (regular) work, but there were over 20 attached. Deep Sigh... ;) Unless you or someone else can quickly come up with another idea or whatever stroke of brilliance I consider this unresolved but closed. Thanks and farewell dramatic chord ;)
3) Message boards : Questions and problems : Can't get Boinc running after restoring a backup. (Message 40692) Posted 17 Oct 2011 by dividedbymyself Post: I just installed Xubuntu 11.10 from CD. Earlier I made a backup of the /var/lib/boinc-client and /etc/bionc-client directories which I restored (overwriting everything already inside the directories) to the appropriate directories on my HD. Now I want to continue were I left off, but BM is complaining it doesn't have the right permissions to open certain files in /var/lib/boinc-client. I tried to change permissions (as root), but I get errors that the permissions of symlinks can't be changed. These symlinks direct to the file ca-bundle.crt and the files in /etc/boinc-client, but these symlinks are not even in my backup, so they can't be overwritten by the restoration. The permissions of the directories are set to read and write for group boinc of both directories. But the /etc/boinc-client is owned by root, not by 'Boinc core client (boinc)' like the /var/lib/boinc-client directory. Also when I start the boinc-client it stops by itself after a short while and BM can't connect to the client. That could be because for the same reason of course. BM can connect to the client when I haven't yet restored the backup. Can anyone help me to get Boinc up and running again from where I left off? I already completely removed and re-installed the Boinc install, but to no avail. Bart

5) Message boards : News : Virtual Prairie results published (Message 38169) Posted 5 Jun 2011 by dividedbymyself Post: According BOINCstats, their last update was 9 days ago, as at this writing: http://boincstats.com/index.php?list=full&or=0 --//-- I can see that on Boinc-manager as well, because I never stopped it from pinging for new work, so my stats are being updated regularly. My question is if we can expect ViP to ever return, i.e., can I remove it from my project list in BM?
6) Message boards : News : Virtual Prairie results published (Message 38167) Posted 5 Jun 2011 by dividedbymyself Post: Does this mean ViP is finished? The serves seems to be dead for some now and when I read the acknowledgements in the paper it's in the past tense. This project benefited from the grant ANR-08-SYSC-012 of the Agence Nationale de la Recherche. Can we expect ViP to return or can 'we' scrap it from the list of active projects? Thanks for the info, Bart
7) Message boards : Projects : News on Project Outages (Message 38166) Posted 5 Jun 2011 by dividedbymyself Post: Thanks for the info SekeRob. Maybe on their forums they announced they're done, but I don't visit it frequently and might have missed it. When I read the acknowledgements is looks like they're done, it's in the past tense. I'll ask in the thread you linked to to keep things on topic. Thanks, Bart
8) Message boards : Projects : News on Project Outages (Message 38164) Posted 5 Jun 2011 by dividedbymyself Post: Looks like this is the week to suffer hardware failure. So far it looks like SETI, CPDN, Milkyway have had problems in the last 7 days. Not that they had work or anything, but I noticed Virtual Prairie's savanna might have gone ablaze as well. Maybe it's the dry season? Does anyone knows anything about them?
9) Message boards : Questions and problems : Day-of-week override settings and scheduler (Message 35076) Posted 2 Oct 2010 by dividedbymyself Post: I don't think its explicitly short-deadline he wants to run, I think it's explicitly Orbit he wants to run. But if Orbit has no work he could use Malaria for testing and Boinc-learning purposes. They also have a 3-day deadline, like Orbit in its last batch. Still Malaria is a good project, so worthwhile to run anyway. Bart
10) Message boards : Questions and problems : Day-of-week override settings and scheduler (Message 35072) Posted 2 Oct 2010 by dividedbymyself Post: The Boinc-scheduler works with longer term averages but doesn't take into account scheduled times the computer is running or not, so stabilization of these parameters wouldn't lead to lifting short deadline projects over the weekend without running into deadlines. It should do this, but it takes time for BOINC to learn. I don't know how long the user tried it, but if it was less than 1 or 2 weeks, it's anyone's guess. That's surprising. I'll convey this and ask him to try a couple of weeks longer before detaching. A problem is Orbit seems to be out of work for some time (this might 'throw soot in the food' :) ) Thanks, Bart
11) Message boards : Promotion : Getting a .edu email address (Message 35067) Posted 2 Oct 2010 by dividedbymyself Post: apt-get install boinc-nvidia That looks like it's straightforward into a dead-end-alley, at least on Ubuntu. Or do you need to add another repository for that? root@Xub64:/home/bart/Desktop# apt-get install boinc-nvidia Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package boinc-nvidia Bart Edit: Jord already gave the answer I suppose.
12) Message boards : Questions and problems : Day-of-week override settings and scheduler (Message 35063) Posted 2 Oct 2010 by dividedbymyself Post: I'm not mixing two concepts, I was just hoping these concepts were mixed. I was not really asking this question for myself but for someone at Orbit who has problems with the short deadlines because he's running Boinc on an office computer and hates to micromanage. On my advice he already tried the Day-of-week override scheduling and came to the conclusion it doesn't work as I was hoping it would. The Boinc-scheduler works with longer term averages but doesn't take into account scheduled times the computer is running or not, so stabilization of these parameters wouldn't lead to lifting short deadline projects over the weekend without running into deadlines.

13) Message boards : Questions and problems : Day-of-week override settings and scheduler (Message 34998) Posted 28 Sep 2010 by dividedbymyself Post: Suppose I run Boinc only during weekdays from 08:00-17:00, not in the weekend and the computer is switched off when Boinc is not running. I could set when Boinc runs in the Day-of-week override settings in the Processor Usage tab accordingly (Saturday and Sunday could be set to minimal time, i.e. 1 minute). Will these settings be accounted for when new work is downloaded? I mean, when a certain project has a 3 day deadline for its work and the computer is switched off during weekends, under normal circumstances (with default Day-of-week override settings) a Wu downloaded on Thursday or Friday may/will be too late to meet the deadline. But will the Day-of-week override settings influence the scheduler so on days before the weekend no work will be downloaded so no deadline will be missed or does the scheduler not take into account these settings? Bart
14) Message boards : Promotion : Getting a .edu email address (Message 34937) Posted 25 Sep 2010 by dividedbymyself Post: I must say I currently don't have any Boinc GPU apps on my Linux (X)ubuntu/CUDA computer so it's untested, but I have the latest Nvidia driver (256.53) installed. It's not really click and go, but not really hard either. I'll explain what I did: - First I disabled the already installed Nvidia driver (in Xubuntu) in the System/Hardware drivers menu. - Download the latest driver for your OS/card from the Nvidia site. - Open a terminal screen and navigate to where you downloaded the driver and make the package executable (I don't know if this is really necessary, but I did it anyway): $ chmod u+x NVIDIA-Linux-x86_64-256.53.run Where the package name may be different of course. - hit: Ctl-Alt-F1 - Type (maybe better write it down as you'll go to a non-graphical screen): $ /etc/init.d/gdm stop to stop the X-server. - Then execute the package: $ sudo sh NVIDIA-Linux-x86_64-256.53.run - Follow the installer instructions, you'll probably get a warning something like "nouveau" has to be disabled, but the installer will do that for you when you click Yes. Write down the files the installer tells you to delete for in case you need to enable nouveau again and stuff like that. - You'll need to reboot, then hit Ctl-Alt-F1 and run the installer again ($ sudo sh NVIDIA-Linux-x86_64-256.53.run). From here things should go straightforward. There was one question if I wanted to enable OpenGL 32 bit or something like that. I said yes, but to be honest I don't know if this was necessary). When the installer is finished do a reboot and everything is supposed to be fine. At least, things were fine with me ;) If you're going to try it and run Linux Boinc CUDA apps, let me know how it works. I'm really curious. I hope it helps, Bart
15) Message boards : Promotion : Getting a .edu email address (Message 34736) Posted 18 Sep 2010 by dividedbymyself Post: One of my major expenses is the OS on a new cruncher. Is Linux not an option? Eg. Ubuntu and its derivatives are easy to learn, are free and doesn't require an email address at all. But there are many more. You can check here what may be the best distro for you. Most Boinc projects have Linux apps (except for LHC) as far as I know. Bart

It's the effect that matters ;) Thanks again, Bart
17) Message boards : Questions and problems : All projects "waiting to run" after update to v.6.10.18 (Message 28824) Posted 18 Nov 2009 by dividedbymyself Post: You possibly have a "cc_config.xml" file in your data directory, left over from previous experiments. And it possibly has the line <ncpus>0</ncpus> in it. That used to be the default for 'ignore me, use everything available'. Now zero means zero: use -1 (minus 1) for the default 'use everything' setting. That was the problem indeed. They're both up and running again. Thanks for you help, faster than lightning :) Bart
18) Message boards : Questions and problems : All projects "waiting to run" after update to v.6.10.18 (Message 28822) Posted 18 Nov 2009 by dividedbymyself Post: I just installed the latest Boinc version 6.10.18 on both my computers that run Boinc, but now no project wants to start running anymore on both of them. They just sit there with status "Ready to start" and "Waiting to run". The only thing I can find is the message: "18/11/2009 17:11:01 Preferences limit # CPUs to 0". I checked the local and remote preferences, but my remote preferences say I allow 16 processors to be used (I only have 1 processor computers) and my remote preferences say Boinc has permission to use 100% of all processors. I don't have any idea were to look anymore and help is appreciated. Thanks, Bart
19) Message boards : Questions and problems : Reinstalling Boinc with backup ono clean Win install (Message 26638) Posted 17 Aug 2009 by dividedbymyself Post: I used the same version: 6.6.31. I read somewhere there are some quirks in the long debt timer/scheduler in 6.6.36, so I thought I'd better not upgrade yet. The v6 LTD baffles me anyway. Just can't figure out how it's exactly supposed to work by looking at the numbers in Boincview... So also in 6.6.31 there are quirks, or maybe these only exist in my mind ;) But that's way off-topic, so never mind. Bart
20) Message boards : Questions and problems : Reinstalling Boinc with backup ono clean Win install (Message 26634) Posted 16 Aug 2009 by dividedbymyself Post: I had some other things to do this afternoon, but I've been working late and got Boinc running again as well. But I installed Boinc first and then made the copies from the backups over the new install and not the other way around as was advised. I think I was just too tired to think. But despite this everything seems to be working fine so far and the projects and Wu's are continuing were they were as if nothing has happened :) Thanks again for the support. Bart
