Well can this idea be presented to the developers of all editions of BOINC and let them think about it and do a poll whether it should be done?


You can register with trac and post an enhancement ticket (http://boinc.berkeley.edu/trac) or join the boinc-dev email list and post your request there (http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev)

I have my preferences set to use 100% of Multi-CPU and 100% CPU Time when computing. I also have it set to switch between applications every 120 minutes.

I have noticed that World Community Grid seems to always be using all four processors and was to understand that each project would use 33.3% of the CPU time and processors when computing. Is this right or do I hav a setting wrong?

Is there a way to make sure each project uses one Processor at a time?

Thank you for your time,
Will


Are you wanting boinc to only run on 1 processor or have all 4 processors running but each with a different project?

If the first then set to 25% of multi cpu, if the second then AFAIK it's not possible to enforce - the boinc scheduler decides what and when it will run - so sometimes you will find it running only one project on all 4 processors other times it might be running two, three or four projects - it depends on what the scheduler decides it needs to run.

I'm more of a Windows person, but you may want to check http://boinc.berkeley.edu/trac/wiki/CompileClient#Linux. Not sure if the Linux build commands are the same throughout the distros.


This was (or at least a prior version of it) was the page I was actually looking to link to (instead of http://boinc.berkeley.edu/trac/wiki/BuildSystem. Thanks Jord

I got it to compile, but now I'm getting a run-time error. Based on the info in your posts, I discovered that I need the following as dependencies to get the manager GUI to compile:

libqt4-opengl-dev
freeglut3-dev
libglui-dev
libwxgtk2.8-0
libsqlite3-dev
libsqlite0-dev

After sudo make install, I get the following terminal output:
jason@jason-desktop:~/Downloads/Utilities/boinc_core_release_7_0_25$ boincmgr
execvp(/home/jason/Downloads/Utilities/boinc_core_release_7_0_25/boinc, --redirectio, --launched_by_manager) failed with error 2!


The client and manager are independent - you can start the client from a terminal (or as a service) and then stop and start the manager independently as you please. Does this make any difference?

http://boinc.berkeley.edu/trac/wiki/BuildSystem should be more up to date than http://www.pperry.f2s.com/boinc-compile.htm.

The aggressive cflags were introduced quite some time ago when benchmarking was integral to the credit system - this is no longer the case. CFLAGS="-march=native -O2 -pipe" should be enough.

Checking through configure.ac "--enable-optimize --enable-bitness=64" seem to be redundant, FWIW the gentoo configure options are "--disable-server --enable-client --enable-dynamic-client-linkage --disable-static --enable-unicode --with-ssl" (I think the last 2 may be gentoo specific relating to wxGTK and CURL)

Again FWIW the gentoo dependencies are openssl, curl with ssl support but not gnutls, util-linux, zlib, sqlite:3, freeglut, glibc:2.2, jpeg, gtk+:2, > libnotify 0.7, < wxGTK 2.8.11.0

I've already brought this thread to Rom's attention, hopefully he is able to offer some assistance.

Last night I downloaded the most recent stable version of boinc 7.0.25 for 64bit Linux. I use 64bit Ubuntu 10.04. When I double click on the boincmgr icon, nothing happens. So, I tried running it in a terminal by typing ./run_manager and it gave me this error:

./boincmgr: error while loading shared libraries: libnotify.so.4: cannot open shared object file: No such file or directory

The output of whereis libnotify is
libnotify: /usr/lib/libnotify.la /usr/lib/libnotify.a /usr/lib/libnotify.so /usr/lib64/libnotify.la /usr/lib64/libnotify.a /usr/lib64/libnotify.so /usr/include/libnotify

[snip]

So, I assume I have libnotify. I must need a simlink, but I don't know how to make simlinks in Linux.


You don't need a symlink - the berekeley version you downloaded was compiled against different versions of the libraries than you have installed. The fix is compile against the libraries that you do have installed.

Also, I have been running the development version of boinc 7.0.3 for 64bit Linux that I compiled without receiving this error. The reason that I want 7.0.25 is that when I compiled boinc I only got boinc and not the GUI manager for some reason


Presuming when you ran the configure command you used
./configure --disable-server
which would cause the client and manager to build, the most likely cause of the manager failing to build is that you are missing one or more dev packages. During the configure stage the output would have paused for a number of seconds and briefly displayed one of the following messages before continuining with the rest of the build process.

Jord/Ageless explains this best here

Do know, that the scheduling code has been rewritten from the ground up. It will not go and fetch work, or schedule which projects to run, as previous versions did.

[T]he new work fetch methods are now based on a low water mark and a high water mark.

BOINC won't immediately after uploading & reporting work ask for new work, but will only do so when it's past the low water mark.

E.g. if you wanted at least a day's worth of work:
In 6.12 and before, you'd set connect to interval to 0.01 and additional work to 1.0

In 7.0 you set minimum work buffer to 1.0 and max additional work buffer to 0.01

Based on your title you've installed the boinc package from the ubuntu repositories - these errors need to be reported back to ubuntu.

https://help.ubuntu.com/community/ReportingBugs

Edit: to explain further a quick google shows that this error code generally relates to an "illegal instruction" - as such - presuming you were previously crunching successfully with a prior ubuntu boinc version and nothing else on your system has changed then the problem lies in the compilation that ubuntu are distributing.

Possible causes - ABI incompatibilty, wrong compiler switch, incorrect dependency

I'm not sure if you can do this by venue (eg default, home and office), give it a try - I'll spin past wcg myself later tonight and have a look at their preferences and see if I can see anything.

Edit: Actually check out the device profiles settings (at wcg web site) I think you can select the projects per device

Checkpoints are application specific. You will need to go the WCG site and check there for details of the checkpointing for each app. You will then have to select in your WCG preferences which apps you can run that will suit your style of operation.

BTW a checkpoint is a point in the calculation that an app can save and then recover from, not all calculations are suited to this.

Don't know about that, I do know my Mac reported computation errors on all the units it is waiting to report. The computer is verifying on other projects. Perhaps it is more than the firewall.

320 WUs and counting, about 12 hours of work according to BOINC's own estimation... that's 0.5 days, way more than 0.01 days.


I've been running the 7.0.x series on 4 boxes and I did notice that kind of behaviour on a couple of projects (predominantly newly added ones) but it sorted itself out - not guaranteeing that this will happen in your case, but let it run its course before abandoning it. I can't remember which projects it was but when it happened I was a bit concerned, particularly as boinc was going into "high priority" mode and it looked as though the wu's from other projects were going to suffer, as it was I think it's just the way the 7 series estimates runtime.

Ubuntu downloads and installs only version 6.33, as 6.34 is not yet in the apt-get database. Boinc Manager keeps sending me notices to download, install, and run v6.34. I am unable to do this as I am a novice at Linux. So I wait for Ubuntu to add v6.34 to its database or someone here to steer me down the path to a successful install of the version from this web site


If you're not overly familiar with linux I wouldn't suggest trying to swap from the repo version to the berkeley version. Just wait for the repo version to be bumped or get in touch with ubuntu maintainers and ask them to bump the repo version.

Ok, after hunting through versions for some time, it turns out that my wxwidgets version was/is too NEW.
I grabbed v6.12.43 and thankfully it lists which version it's compiled against: 2.8.11
My system was running wxWidgets 2.8.12
So far it's running nicely, though I will try to provoke it a little more before declaring this "solved".


This is a problem on gentoo and other distros - gonna try recompiling against 2.8.11 and will report back

Edit: Success on 1 Box will confirm on my other boxes
Edit 2: Confirmed this on 5 boxes
