#emc-devel | Logs for 2008-04-29

[12:23:31] <skunkworkshardy> biab
[12:49:14] <skunkworkshardy> 1.25gb memory
[12:53:42] <alex_joni> whee :)
[13:00:18] <skunkworks_> anything I can do? I have emc-axis running - and about 10 browsers up..
[13:07:03] <skunkworkshardy> and spreadsheet app, word proccessor
[13:08:20] <cradek> try to use up so much ram that it begins to swap
[13:08:25] <cradek> you can see this if you watch top
[13:08:35] <cradek> then see if emc survives
[13:09:52] <skunkworks_> ok
[13:14:21] <skunkworkshardy> cradek: http://pastebin.ca/1001752
[13:14:46] <cradek> Swap: 0k used
[13:14:49] <cradek> try harder!
[13:15:43] <jepler> find /usr -exec md5sum {} +
[13:18:53] <skunkworkshardy> wow - this is hard to do :)
[13:19:05] <skunkworkshardy> windows would be swapping a long time ago ;)
[13:36:22] <skunkworkshardy> http://pastebin.ca/1001775
[13:36:26] <skunkworkshardy> whew
[13:36:52] <fenn> just load up firefox :)
[13:36:57] <SWPadnos> can you load a few images into gimp or something? 128k swap used is pretty wimpy :)
[13:37:10] <skunkworks_> jeeze - what do you want from me?
[13:37:20] <SWPadnos> more swap! muahahahahaha
[13:48:52] <alex_joni> skunkworks_: try the command jepler suggested
[13:48:59] <alex_joni> maybe a couple times in different terminals
[13:54:31] <skunkworkshardy> http://pastebin.ca/1001788
[13:55:30] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[13:56:48] <skunkworkshardy> http://imagebin.org/17217
[13:56:50] <alex_joni> skunkworkshardy: more load, more load
[13:57:07] <alex_joni> * alex_joni snickers
[13:57:21] <alex_joni> skunkworkshardy: you still have an empty second workspace :D
[13:57:28] <skunkworkshardy> heh
[13:57:39] <skunkworkshardy> I am up to 1.6mb swap now
[13:57:59] <alex_joni> lol
[13:58:26] <SWPadnos> so I guess 1GB should be enough for most people ;)
[13:59:37] <alex_joni> SWPadnos: still, I wouldn't want to restrict it to 1GB
[13:59:54] <SWPadnos> no, of course not!
[14:00:01] <SWPadnos> some of us *NEED* more :)
[14:00:13] <SWPadnos> (possibly even for computing tasks)
[14:00:15] <alex_joni> right.. so if the newer RTAI fixes it..
[14:00:15] <skunkworkshardy> http://imagebin.org/17218
[14:01:13] <alex_joni> skunkworkshardy: that display problem.. is it because of snapshot?
[14:01:27] <alex_joni> in topo below 3866 messageb
[14:01:45] <alex_joni> (looks like the snapshot happend just during top's update)
[14:02:12] <cradek> it's so strange to see irc with smiley icons etc
[14:02:22] <cradek> especially when it's the same text as on my screen
[14:02:31] <alex_joni> yeah.. same here
[14:02:32] <SWPadnos> not for me, but my smilies are smaller
[14:02:54] <alex_joni> * alex_joni ponders a donation for SWPadnos
[14:02:59] <SWPadnos> heh
[14:03:02] <alex_joni> then you can buy bigger smilies
[14:03:09] <SWPadnos> no, I don't need a bigger smilie fund
[14:03:12] <alex_joni> (and give the small ones to cradek)
[14:03:15] <cradek> http://timeguy.com/cradek-files/emc/irc.png
[14:03:21] <cradek> thanks, but I don't need them
[14:03:28] <SWPadnos> icky but useful text mode
[14:03:35] <alex_joni> that's a sure fugly font :)
[14:03:48] <cradek> I like it, but probably only because I'm used to it
[14:04:07] <cradek> one thing that's nice is I can tell all the letters and numbers apart
[14:04:14] <cradek> l1l1l1
[14:04:14] <SWPadnos> whoa
[14:04:22] <cradek> Il1Il1
[14:04:25] <cradek> yeah isn't that novel?
[14:04:42] <SWPadnos> damned proportional fonts
[14:04:58] <skunkworks_> alex_joni: yes - that is where the snapshot window was. I think when it is running really slow - the snapshot window doesn't get out of the way fast enough
[14:05:31] <alex_joni> http://imagebin.org/17219
[14:06:08] <skunkworks_> so - is there a >1gb issue?
[14:06:24] <alex_joni> skunkworks_: theoretically there should be
[14:06:31] <skunkworks_> heh
[14:07:11] <SWPadnos> is it a problem with memory usage or DMA/IO or something?
[14:14:42] <alex_joni> SWPadnos: no, the issue is that RTAI doesn't correctly allocate RAM above 1GB
[14:14:53] <alex_joni> so it can overwrite kernel memory
[14:14:58] <SWPadnos> ok
[14:15:08] <alex_joni> skunkworks_: try stopping emc, leaving the other things running
[14:15:10] <SWPadnos> so the test would be to load the system down, then load an RTAI app?
[14:15:12] <SWPadnos> right
[14:15:13] <alex_joni> then starting emc again
[14:15:25] <skunkworks_> I stopped emc - then restarted it. so far.
[14:15:29] <skunkworks_> it is working
[14:15:31] <SWPadnos> but start something else in between
[14:15:41] <skunkworks_> okm
[14:15:47] <alex_joni> skunkworks_: the errors will apear on the userspace programs
[14:15:57] <alex_joni> OO or any of the md5sums
[14:16:05] <alex_joni> not sure you will catch them..
[14:16:26] <alex_joni> having 9 firefoxes open, you might not notice if one disappears
[14:17:42] <rayh> I've seen emc fail to start a couple times and it kills off my keyboard. Don't know what I was doing just before though.
[14:17:53] <skunkworks_> done
[14:21:44] <alex_joni> * alex_joni runs home
[14:21:45] <alex_joni> bbl
[14:50:06] <skunkworks_> is there a way to count the number of applications running? (like how many icons in the taskbar) so that I could tell if one dropped out?
[14:53:18] <SWPadnos> ps ax | wc -l
[14:53:27] <SWPadnos> that'll list processes though, not "windows"
[14:53:53] <SWPadnos> err - it'll count processes anyway
[14:57:04] <skunkworkshardy> it is just unreal with all the stuff running that I am not getting any overruns. rtai must work ;)
[14:58:02] <skunkworkshardy> 2.6mb swap
[14:58:28] <skunkworkshardy> 121 proccesses
[15:00:03] <SWPadnos> have you loaded some gimp thing yet?
[15:00:14] <skunkworks_> a few
[15:00:19] <SWPadnos> download a n image from bluemarble (.org?)
[15:00:22] <SWPadnos> a big image :)
[15:00:43] <skunkworks_> I was also trying to run a movie.. but the 2 movie files I have found will not run in the player
[15:02:27] <SWPadnos> load one of these images: :) http://mirrors.arsc.edu/nasa/world_big/
[15:03:03] <SWPadnos> hmmm. actually those are raw data
[15:03:11] <SWPadnos> try one of these: http://mirrors.arsc.edu/nasa/world_500m/
[15:03:41] <SWPadnos> heh - oops
[15:06:57] <skunkworks_> logger_dev: bookmark
[15:06:57] <skunkworks_> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2008-04-29.txt
[15:09:05] <skunkworks_> hmm big files :) this one is going to take 15 minutes
[15:39:12] <skunkworkshardy> http://imagebin.org/17222
[15:40:05] <skunkworks_> emc doesn't run too bad.. But everything else is pretty slow.
[15:40:56] <SWPadnos> ok - 1.25GB swap, that's a good load :)
[15:48:13] <skunkworks_> still running. nothing dropped out yet.
[15:48:28] <skunkworks_> Definatly is unreal
[15:48:48] <skunkworks_> try that with windows and mach
[15:48:52] <skunkworks_> ;)
[15:49:19] <skunkworks_> * skunkworks_ going by what he has heard
[15:49:20] <SWPadnos> I'm sure it would be fine, until you load winamp ;)
[15:49:58] <SWPadnos> http://www.tormach.com/document_library/SB0012_Control_Computers.pdf
[15:50:04] <skunkworks_> From reading cnczone.. you don't want anything running other than mach. (something might happen)
[15:50:12] <SWPadnos> at least someone else knows that not everything works right
[15:50:20] <SWPadnos> yep
[16:14:47] <jepler> I'm tempted to try this on my laptop: http://hoegsberg.blogspot.com/2008/03/i-just-committed-last-bit-of-dri2-work.html
[16:14:51] <jepler> looks pretty cool
[16:15:23] <jepler> if I was only sure what code to check out, and from where, to do so...
[16:43:25] <alex_joni> skunkworks_: whee.. that's sure some stress testing :)
[16:51:11] <skunkworks_> still going
[16:51:35] <alex_joni> skunkworks_: you might have gotten the unbreakable one :)
[16:51:42] <alex_joni> or maybe you have too little RAM :P
[16:51:49] <alex_joni> (swap is ok now)
[16:51:59] <skunkworks_> I could add more..
[16:52:41] <alex_joni> skunkworks_: I remember on dapper it was quite easy to expose it..
[16:59:06] <skunkworks_> yes
[16:59:19] <skunkworks_> I thought emc would't even start...
[16:59:22] <alex_joni> was it you that had the problem?
[16:59:35] <alex_joni> skunkworks_: no, it starts.. and emc has no problems with running
[16:59:52] <alex_joni> it's just other userspace apps that can get corrupted
[17:00:06] <skunkworks_> yes - I think I was the first one that had a machine >1gb
[17:00:22] <alex_joni> ever?
[17:00:23] <alex_joni> :P
[17:00:34] <skunkworks_> jmk and cradek had dialed in an worked on it to figure out the problem
[17:00:40] <skunkworks_> ;)
[17:00:47] <skunkworks_> that reported it I guess..
[17:00:51] <alex_joni> I remember also ssh-ing in
[17:00:56] <alex_joni> together with cradek
[17:01:04] <skunkworks_> ah - right
[17:04:25] <skunkworks_> * skunkworks_ is wondering if jepler is feeling rushed now about the 8255 driver. ;)
[17:04:47] <alex_joni> heh
[17:47:21] <skunkworkshardy> biab
[18:22:19] <CIA-31> EMC: 03alex_joni 07TRUNK * 10infrastructure/repositories/hardy/ (5 files): hardy scripts to build the repository
[18:31:51] <skunkworkshardy> I think I might have killed gimp
[18:32:06] <skunkworkshardy> it doesn't like opening a 300+mb file
[18:32:21] <alex_joni> hah
[18:50:28] <skunkworkshardy> http://imagebin.org/17235
[18:53:44] <skunkworks_> I am running stepper inch - so it is also running a 50us base period
[18:55:20] <skunkworks_> impressive
[18:55:50] <cradek> wow you must have something large in eog
[18:56:15] <skunkworks_> eog?
[18:58:58] <skunkworks_> is eog the image viewer?
[18:59:05] <cradek> yes
[18:59:14] <skunkworks_> I have atleast 2 open with 300+mb files in them
[19:01:16] <tissf> hello all
[19:02:02] <skunkworks_> Hi
[19:04:42] <tissf> I am very happy with the heron, emc2 work like a charm :)
[19:14:38] <alex_joni> tissf: that's good to hear
[19:27:50] <skunkworks_> I had to close out one of the image viewer.. everything slowed to a crawl
[19:29:54] <alex_joni> skunkworks_: if you didn't see any corruption.. then I'd say you're not seeing the bug
[19:30:06] <skunkworks_> right
[19:30:19] <alex_joni> (you can use M in top, to sort by memory usage)
[19:32:16] <skunkworkshardy> eog is using the most
[19:32:29] <skunkworkshardy> then firefox and xorg
[19:32:37] <alex_joni> at 2.7G virt.. I'd say so :)
[19:33:00] <skunkworkshardy> down to 778MB virtual used now.
[19:33:09] <skunkworkshardy> running pretty zippy
[19:37:26] <alex_joni> skunkworkshardy: what machine is that?
[19:38:25] <skunkworkshardy> 2.4ghz pent 4
[19:40:34] <skunkworkshardy> I had crashed out of gimp a few times - don't know if that is what caused the slowdown.. (unrelated to emc)
[19:41:01] <skunkworkshardy> (just wouldn't load the 300+MB file.)
[20:05:16] <alex_joni> hmm.. mksquashfs is so much slower with only one processor
[20:06:59] <CIA-31> EMC: 03alex_joni 07TRUNK * 10infrastructure/livecd/hardy_i386.livecd: add doc describing how to build the hardy livecd
[20:12:55] <skunkworkshardy> bbl
[20:41:06] <alex_joni> wb :)
[20:41:39] <skunkworkshardy> alex_joni: I ran update manager and there is a rtai update 2.6.24-16-rtai
[20:41:55] <skunkworkshardy> (only update)
[20:42:00] <alex_joni> rtai-modules-2.6.24-16-rtai updated
[20:42:07] <alex_joni> to version 3.6-linuxcnc.2
[20:42:19] <skunkworkshardy> so - this is ok?
[20:42:22] <alex_joni> yup
[20:42:27] <alex_joni> adds RTDM
[20:42:37] <skunkworkshardy> this is a dual core
[20:42:56] <skunkworkshardy> installed in about 10 minutes.. I love sata
[20:43:17] <skunkworkshardy> Should it ask me to reboot? It isn't
[20:43:28] <alex_joni> it shouldn't
[20:43:32] <skunkworkshardy> good ;)
[20:43:37] <alex_joni> this ain't windows :)
[20:43:52] <alex_joni> only a new kernel needs a reboot
[20:44:03] <alex_joni> fresh new livecd :)
[20:45:23] <skunkworkshardy> this has 2GB ram also
[20:45:47] <alex_joni> another box?
[20:46:24] <skunkworkshardy> yes
[20:46:28] <alex_joni> coo
[20:46:49] <skunkworkshardy> dual core. don't know the speed
[20:46:58] <alex_joni> cat /proc/cpuinfo :)
[20:47:00] <alex_joni> (if you care)
[20:47:32] <skunkworkshardy> Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz
[20:47:48] <alex_joni> cool.. 10 mins is really great
[20:47:57] <skunkworkshardy> it is - suppriesed me
[20:48:38] <alex_joni> try that again :D
[20:48:55] <skunkworkshardy> surprised ?
[20:48:58] <skunkworkshardy> ;)
[20:49:07] <alex_joni> skunkworkshardy++
[20:49:47] <skunkworkshardy> lets see if gimp opens this file on this machine :)
[20:51:55] <skunkworkshardy> hammering away
[20:52:18] <alex_joni> finally..
[20:52:23] <alex_joni> Check finished: no errors found
[20:52:28] <skunkworkshardy> sweet
[20:52:47] <alex_joni> I manged to build a good one ..
[20:55:08] <alex_joni> (at least that's my hope)
[20:55:53] <skunkworkshardy> wow - loaded
[20:58:09] <skunkworks_> I guess you just need to be patient
[20:59:29] <alex_joni> talking to yourself?
[20:59:46] <alex_joni> brb, booting it now
[21:02:06] <skunkworks_> yes
[21:08:58] <skunkworkshardy> http://imagebin.org/17245
[21:10:01] <alex_joni> meh.. 6GB of swap?
[21:10:41] <skunkworks_> how does it descide that?
[21:11:00] <skunkworks_> ratio of the total disk size?
[21:11:07] <alex_joni> it saw how much you try to push it
[21:11:10] <alex_joni> ROFL
[21:11:21] <skunkworks_> the previous computer had around 2gb
[21:11:25] <alex_joni> (the word is out on the internet now.. all your machines will have huge swap)
[21:11:32] <skunkworks_> heh
[21:11:59] <alex_joni> it might have phoned home.. to warn for other 'samco' users/machines
[21:12:42] <CIA-31> EMC: 03alex_joni 07TRUNK * 10infrastructure/livecd/hardy_i386.livecd: add some content
[21:19:14] <skunkworks_> rtdm = real time device layer?
[21:20:02] <alex_joni> real time driver model
[21:20:04] <skunkworks_> 2 computers now 'seem' to run ok with over 1GB ram
[21:20:36] <skunkworks_> oops - right
[21:22:59] <alex_joni> oops-right?
[21:24:29] <skunkworks_> I read - real time drive model on the web - and wrote 'real time device layer' on here.
[21:24:56] <alex_joni> heh.. close enough
[21:25:05] <skunkworks_> I thought so ;)
[21:29:30] <CIA-31> EMC: 03alex_joni 07TRUNK * 10infrastructure/livecd/hardy_i386.livecd: add info on ubiquity/apt-setup/generators for emc2 repo
[21:30:09] <skunkworks_> alex_joni: you're so busy
[21:30:10] <skunkworks_> :)
[21:38:04] <alex_joni> skunkworks: any of you still around?
[23:26:11] <rayh> I see an update to rtai modules. Is that us?
[23:52:04] <SWPadnos> [16:43:40]<alex_joni>rtai-modules-2.6.24-16-rtai updated
[23:52:06] <SWPadnos> [16:43:47]to version 3.6-linuxcnc.2
[23:52:12] <SWPadnos> looks that way
[23:57:49] <rayh> Great thanks Steven
[23:57:54] <SWPadnos> sure
[23:58:17] <rayh> You get that cold weather up there yet?
[23:58:27] <SWPadnos> it's getting here
[23:58:40] <rayh> 15f last night here. Darn short summer.
[23:58:45] <SWPadnos> about 35 degrees right now, apparently there was snow about 15 miles north of me
[23:58:47] <SWPadnos> heh
[23:59:08] <rayh> skunk said he got snow yesterday. we had some the day before.
[23:59:39] <SWPadnos> what's funny is that Sharon and I were in LA (Santa Monica) last week, and it was warmer here than in SoCal
[23:59:58] <rayh> Maxine nearly beat me up. I got her a cup of coffee and sang "Im dreaming of a white christmas.
