IRC logs of #boinc for Monday, 2012-10-01

00:05 <Tank_Master> i didnt know there was an optimized app for LHC

00:09 <dddh> I see sixtrack_linux_pni, sixtrack_linux_sse2 and sixtrack_linux_sse3 in /var/lib/boinc/projects/lhcathomeclassic.cern.ch_sixtrack

00:10 <MTughan_> Were they downloaded automatically from LHC?

00:10 *** MTughan_ is now known as MTughan

00:13 *** efc has joined #boinc

00:26 <dddh> MTughan: yes, all of the apps I have on that PC were downloaded automatically

00:28 <MTughan> dddh: Then they're not considered "optimized apps" per se. An optimized app in BOINC terms refers to an app compiled with optimizations that has to be inserted manually. It doesn't usually refer to apps downloaded automatically by the project.

00:28 <MTughan> Just a terminology thing, but I think that's what confused Tank_Master. :P

00:32 <dddh> MTughan: ok ;)

00:33 <MTughan> As for why the app is crashing or causing errors, we'll need more information. Logs are always helpful. :)

00:34 <dddh> I'll check logs

00:42 <dddh> I didn't find logs on my side about those completed tasks

01:07 <dddh> MTughan: is it possible to check why lhcathomeclassic.cern.ch/sixtrack/results.php thinks status is Error("Error while computing")?

01:08 <MTughan> dddh: There should be a log file attached to the workunit if you go into the description of the WU. It's the stderr output from the worker app.

01:10 <PovAddict> dddh: we can't get info without your user ID or something

01:10 <PovAddict> dddh: http://lhcathomeclassic.cern.ch/sixtrack/show_user.php?userid=243486 is this you?

01:10 *** efc has quit IRC

01:10 <Romulus> <http://tinyurl.com/9z8m5mh> (at lhcathomeclassic.cern.ch)

01:12 <MTughan> "process got signal 11"… Well, that's helpful. :/

01:12 <dddh> PovAddict: yes

01:13 <PovAddict> ugh

01:13 <MTughan> What is that, a segfault?

01:13 <PovAddict> yes

01:13 <PovAddict> 11 is sigsegv

01:14 <PovAddict> MTughan: hard to tell what happened without a stacktrace, and even then, we don't have the debugging symbols

01:14 <MTughan> Right.

01:14 <dddh> I'll detach this pc from lhc@home

01:15 <PovAddict> dddh: wait

01:15 <MTughan> You can just mark LHC as suspended for now, you don't have to detach it.

01:15 <dddh> guess it's time to add my 2 ec2 nodes

01:15 *** zombie67 has quit IRC

01:15 <PovAddict> nevermind, I got the file myself

01:15 <PovAddict> holy crap

01:16 <PovAddict> MTughan: there *are* symbols

01:16 <MTughan> The executable has debugging symbols in it? Why would they do that?

01:16 <MTughan> Or are they available separately?

01:16 <PovAddict> hm

01:17 <PovAddict> maybe not debugging symbols

01:18 <PovAddict> but function names are there at least

01:19 <PovAddict> no line number information

01:27 <dddh> I guess I could compile those apps myself to check

01:27 <PovAddict> they are open source?

01:29 <dddh> I don't know

01:47 *** Caterpillar has joined #boinc

02:16 <dddh> PovAddict: where did you find app symbols?

03:27 *** Caterpillar has quit IRC

03:44 <dddh> replaced that PC with 2 ec2 nodes in LHC@

03:45 <dddh> ;(
