I just reinstalled Ubuntu on my server today, switching from 10.04 to 12.04

now every WU downloaded throws a computation error instantly upon trying to run. I have not had one WU even begin to process. They just error.

blah. any ideas

It's a xeon, no GPU, never had an issue in the past.

Thanks Arkyan. Apparently I even posted on one of those threads.

So I've got a bunk install of boinc. Blah.
How does software end up in a repo with a bug like this......!!! <shakes fist>

Well, I guess since I don't wanna compile anything, it's off to harass the buntu folks to fix the repo version...

And get an older one installed in the meantime.

I'm done for the day. Looks like my crunching is dropping to "0" for a bit.

Another "bug" I've seen with this version is:

"Xlib: extension "MIT-SCREEN-SAVER" missing on display..."

I run my linux boxes via ssh and on my 12.04 test box I noticed that error forcing its way on to my command line repeatedly. It still does it of course.

If that doesn't get fixed I'm not going to run boinc on my best machine, because I will not put up with that message filling my screen overwriting whatever im working on from command line.

In the next day or two I'll get the boinc from the 10.04 repo installed on my server as it produces neither of these mentioned issues.

I've uninstalled the 7.0.24 Ubuntu version and installed 7.0.26 manually and copied all the optimized apps, seems all works OK now. It was easier than I first thought it would be, but I wont switch to Linux any day soon as my primary OS ;)

Ok, I jumped over to launchpad and harassed the package maintainer with a bug report for 12.04 and 7.0.24/25 with the computation error. Along with another bug report for the "Xlib: extension "MIT-SCREEN-SAVER" missing on display..." error that pops up on command line while boinc is running.

I'll let you know when I hear back.

A package maintainer got back to me already. He was kind enough to give me his ppa repository link. I have installed 7.0.26 on my ubuntu. As soon as I get given some workunits I'll let you know how it goes.

The package maintainer asked me to verify the bug is fixed in 7.0.26. So hopefully if so it can be moved into the Ubuntu repos sooner than later.

---

#resist

Um so who said 7.0.26 had fixed this issue?????


Because it is indeed NOT fixed in 7.0.26

The package maintainer even mentioned that there was no note in his changelog that the bug was resolved with 7.0.26.

Since I installed 7.0.26 I haven't had the CPU error.

One example

http://setiathome.berkeley.edu/result.php?resultid=2413005565

What exactly was the nature of your error.

In my case it's:

I run a xeon server, no gpu. used buntu 10.04 and boinc 6.something
Did not have any issues.

Upgraded to 12.04, installed boinc 7.0.24.

As soon as a WU begins to process it instantly stops and shows status "computation error". It happens so quick that as soon as a WU is downloaded it's instantly wasted, and the list runs out of tasks. It will not/ has not/ can not process a single second of a single WU since the change to 7.0.24 and buntu 12.04.

and to recap the package maintainer at lauchpad had me try 7.0.26, in which the issue still persists.

My p4 system when tested a few weeks back did not have the issue with erroring. only my 64bit xeon system has this issue.

Using Ubuntu 11.10 and BOINC 6.12.33 I had no problem.

Upgraded to Ubuntu 12.04 and BOINC 7.0.24 and I also got the instant CPU error.

One example

http://setiathome.berkeley.edu/result.php?resultid=2412287516

But you say it was fixed when changing to 7.0.26? I mean you're using 64 bit linux so I'd assume I'm having the problem that you're not anymore...

Is there something I perhaps did not remove from my system, i.e. leftover files and the like. Maybe I need to get rid of stuff and then try to install 7.0.26 again?

---

#resist

Only difference that I can see is John installed from BOINC and is running from his user account.

Can both of you post the first 20 lines of the startup messages.

One difference may be that I tried updating Ubuntu from 11.10 > 12.04 but the install got stuck, I had to reset and then Ubuntu wouldn't load. I then did a fresh install of 12.04 so there's nothing left from 11.10.

btw why does BOINC report my GPU having 134215223MB of RAM??

Why is your data directory in /home/administrator, normally it should be /var/lib/boinc/.

Might want to try a full uninstall and reinstall.

---

My install is also a clean full install of 12.04, nothing left of previous bits.



And I've uninstalled, purged, and installed this several times. Perhaps there is a way I can change the data directory manually? I also see the other user posting with me has his data in his user directory, not the one you mentioned

---

#resist

/var/lib/boinc/ should be the data directory when you install from the repository.

John's is different because he downloaded from BOINC and installed it to his home directory.

---

Hmm. Well it's from a ppa repository, installed by APT. perhaps the version in the PPA repo has an error in where it's putting data?

Is there any way to change this manually? Or perhaps SUing to root before the install from the ppa repo?

---

#resist

one more note, why does my readout have a "virtualbox" version line, and John's does not?.... WTH?

(I do have virtualbox installed but what does that have to do with running boinc.)
