Hello crunchers,

When having trouble with Nvidia driver/Ubuntu Server 12.04.4 and PGU cruching data.
Is it then more safe/better to use the "apt-get install boinc-client" command rather than the boinc repository "add-apt-repository ppa:costamagnagianfranco/boinc"??

Apt-get will get you the latest BOINC from repository, which can be a quite old version, depending on how well it's updated by the package maintainers (who aren't the BOINC developers, btw). This can be old BOINC 6 versions, but also 'broken' beta versions that they set to recommended (such as 7.0.27).
Using Gianfranco's PPA you have a bigger chance that you're up-to-date to the Berkeley recommended version, as Gianfranco will try to keep it in sync with Berkeley. He'll also report back to the developers when he finds it won't build, for some reason.

(3 edits to get Gianfranco's name right. Had to look it up, to be sure. Gianfranco Costamagna. :-))

Hello Mr. Ageless,

Thank you ;)

OK, that's the one I use, the one you showed me last year btw ;) The reason I ask, is that several sites containing the issue problems with GPU/Nvidia cards/Ubuntu 12.04 suggest this as a problem.

I will stick with Mr Gianfranco Costamagna ;)

Remind me, why can't you use Berkeley's version of BOINC and do you need to use third party versions?

Hello Mr. Ageless..

I'm running version:
# boinccmd --version
boinccmd, built from BOINC 7.2.33

I use the repository we talked about, from mr. Giancarlo.

I can see from the link you just send me, that there's a newer version, version 7.2.39 - do you think that will make any change? I will try to make the 32 clean installation of the server and then use this driver instead. I'm not giving up. I bought a lot of equipment, and I'm not going to install windows on those machines! ;)

How do you install such a downloaded file? I use wget *filename to DL it, then I give it permission to execute the .sh file. Then I sh filename.sh, but it didn't work with this file. On SETI installation site, we are told to use apt-get install boinc-client, just as I'm use to. But this doesn't install boinc v.7.2.39 from the download page!?

I found some guys in the US and in the UK, which might just have a solution to the problem. This is the link to the issues they had. Just like me.:
"Fractal" from the states: http://www.gpugrid.net/forum_thread.php?id=3371&sort=5#30010
"Dave" from the states as well: http://www.gpugrid.net/forum_thread.php?id=3083
It's just that this is some time ago, and therefore I contacted them directly to find the solution. Hope it works...

If I misunderstood your question, I'm sorry.. I totally beat. Long hours, late nights, you know how it is, I'm sure :)

I didn't mean to tell you to use BOINC 7.2.39 from Berkeley, I only asked why you use the version from repository/PPA? Also, you can't install the Berkeley version in the same place as the one from repository, so don't try to update to it at this time, or not until one of the Linux gurus tells you step by step how that can be accomplished.

All I wondered was if there was a specific problem why you can not use the Berkeley version (which is built and tested on Ubuntu 12.10 LTS)?

Hello again,

No reason at all. I only use the repository because I was told it was a smart thing to do.
But I'm considering giving in and use another OS until the solution had been found. Draco says he has a way, but this means I have to switch to yet another type of Linux.
I think I might try the Desktop version, to see if this works. Then X is installed and everything and I can use the boinc manager to se if its working (i think, I'm not sure if you can se GPU in boinc-manager)
Then I could use the drivers from BOINC's download page ;)

Are you running several computers? If, what do you use? Do you remotely control them? And if you do, how?

One important question:
Please explain this. "...On Linux you can install BOINC as a service daemon and on certain distros configure X-server to allow BOINC access to the GPU.."

Hello again,

Question:

I'm currently reading this, Mr. Giancarlo is named several times. Can this be some sort of repository or package which would help? Maybe? If you got the time, please take a look:
https://launchpad.net/ubuntu/precise/+package/boinc-nvidia-cuda

Please explain this. "...On Linux you can install BOINC as a service daemon and on certain distros configure X-server to allow BOINC access to the GPU.."
http://boinc.berkeley.edu/wiki/GPU_computing


In clean installation of Ubuntu DESKTOP 12.04.4:
And trying to follow the BOINC help on installing the boinc

1. Guide tells us to download and install from here http://boinc.berkeley.edu/download.php
But after download I try to run the installation file. You cant "dobbeltclick" as it says, then we do it the old way, make bootable and sh filename.sh or ./ filename.sh you are told to start "run_manager" Try that, and it goes on and on.
Just need a way to install "boinc_7.2.39_x86_64-pc-linux-gnu.sh"

2. On another BOINC help page, you are told to do this to install BOINC under Ubuntu: aptitude(apt-get) install boinc-client boinc-manager
http://boinc.berkeley.edu/wiki/Installing_BOINC_on_Ubuntu
But then you are not using the file above, and not following the installation todo.

Why is it so difficult, to install these files?


Thanks in advance ;)

Hello friends ;)


Almost solved. Wrong edition, right result!

New attempt to solve the issue "Ubuntu Server 12.04.4 64bit - BOINC using GPU - Nvidia driver/GeForce GT610"

Just finishing the clean installation of Ubuntu Desktop 12.04.4 (Desktop, not Server!) Not being able to install the file from BOINC's download site, I did this instead "apt-get install boinc-client boinc-manager" which is showed on BOINC helping pages. But this does not install the newest boinc version. And now a notice tells me to download and install the new version.... etc. etc. never mind that right now.

But, after installing this desktop version, and installing boinc-client and boing-manager, and attaching to project using the manager, I checked to see if the GPU was running. Not yet, so I went on DL the newest driver from Nvidia 64bit 331.38. and making it bootable "chmod +x filename.run". Running the file gave me the same problems as when doing this on the Ubuntu Server Edition! So I went on, doing the same as I did there, almost.
I started a terminal, ctrl-alt-f2 and logged in, the claiming sudo rights "sudo su", then "stop lightdm", then running the Nvidia installer "sh NVIDIA-Linux-x86_64-331.38.run". Some questions are asked during the installation, I answered "Yes" to [install 32bit libraries etc.], "Yes" to [reconfigure X-server or something like that] (I will make a better todo when this is all finished!!)
Rebooting the system and updating the project from Boinc Manager showed me a 5 running unit. (CPU i5-3470 has 4 cores) and this 5 unit is named: (0.01 CPUs + 1 NVIDIA GPU). This I also found when doing it with Ubuntu Server 12.04.4, but the GPU ran for 7 minutes and the the temp. of the GPU suddenly dropped. This meaning the crunching also stopped. But not with the Ubuntu Desktop 12.04.4, here the GPU has been running now for 47 minutes and the GPU is still 47 degrees Celsius!
Here's the log file from Boinc Manager and a screen-dump of Boinc Manager showing the GPU crunching still after more than 10 minutes.:

OK, I couldn't upload a screendump, it's not possible in this forum. The reason I would like to show you this screendump is because when 4 work units were done after about 50 minutes, the GPU had only completed about 5-6% of it's work unit.
I know this card GT610 is a "not very fast" card. We discussed this inhere. But I also learned that GPU's would be much faster doing data crunching that ordinary CPU's !! I will replace the GT610 with the faster Asus GeForce GT640 which I was told would be a much better choice. But how much better will it be?

What is the reason for doing all this work, if GPU's are so much "slower" than an ordinary Intel i5 CPU? How fast is a "fast" graphic card" compared to e.g. i5-3470?

We now know that the hardware in this test works, and we know that it runs on Ubuntu Desktop 12,04.4. OK, then why will it not run on Ubuntu Server 12.04.4? The only difference is the graphical environment, X-server! According to Ubuntu, there's not the difference of the Desktop Edition and the Server Edition as earlier on, e.g. Ubuntu Server 10.04 v. Ubuntu Desktop 10.04!
So why is this? Why will the GPU not work properly?

Any suggestions will be greatly appreciated at this thread:

OK, I couldn't upload a screendump, it's not possible in this forum. The reason I would like to show you this screendump is because when 4 work units were done after about 50 minutes, the GPU had only completed about 5-6% of it's work unit.
I know this card GT610 is a "not very fast" card. We discussed this inhere. But I also learned that GPU's would be much faster doing data crunching that ordinary CPU's !! I will replace the GT610 with the faster Asus GeForce GT640 which I was told would be a much better choice. But how much better will it be?

What is the reason for doing all this work, if GPU's are so much "slower" than an ordinary Intel i5 CPU? How fast is a "fast" graphic card" compared to e.g. i5-3470?

We now know that the hardware in this test works, and we know that it runs on Ubuntu Desktop 12,04.4. OK, then why will it not run on Ubuntu Server 12.04.4? The only difference is the graphical environment, X-server! According to Ubuntu, there's not the difference of the Desktop Edition and the Server Edition as earlier on, e.g. Ubuntu Server 10.04 v. Ubuntu Desktop 10.04!
So why is this? Why will the GPU not work properly?

Any suggestions will be greatly appreciated at this thread:

gt610 looks be very weak - about 155 GFLOPS only.
i think, gt630 rev 2 ( gk208 , with 692 GFLOPS - look for 64 bit memory. 128 bit is old 630!) is very good - it also have a best watt / gflops ratio.
gf640 is only 25% faster than gt630, and consume 2x more power, and cost also about 1.5x more. i think, gt630 may be an optimal choice.
there is some info about nv cards:

Closing thread...

Almost success. Wrong OS edition, right result!

Will be followed up by a todo, if we succeed, in one of these two threads:
