| braddr | fabbione: hey.. hopefully your day off was unproductive. :) | 04:57 |
|---|---|---|
| fabbione | morning | 06:56 |
| fabbione | oh yeah indeed | 06:56 |
| braddr | excellent | 07:03 |
| braddr | though I'm gonna disrupt that trend for a sec.. I kinda quit doing parallel builds on that t2000. I don't suppose you and/or dave have a potential fix for that boot cpu issue, eh? | 07:04 |
| braddr | the only issue I hit during those builds was the file-max thing. As long as I kept the parallelism low enough (800ish I think it was) it'd run for days. | 07:05 |
| fabbione | no that's the next in the queue | 07:05 |
| fabbione | i am testing the T1000 fix right now | 07:05 |
| === braddr nods. | ||
| === braddr is expecting the send it now or let us charge you for it email any day now, sadly. | ||
| fabbione | i wonder.. can you slam /proc/cpuinfo somewhere? | 07:06 |
| fabbione | yeah i know :( | 07:06 |
| braddr | oh, sure... just a sec | 07:06 |
| braddr | http://www.puremagic.com/~braddr/t2000/cpuinfo.txt | 07:07 |
| fabbione | thanks | 07:09 |
| fabbione | humpf | 07:10 |
| fabbione | the cpu are all in sequence | 07:10 |
| braddr | yeah.. nothing stood out to me as odd | 07:11 |
| fabbione | i have a kenrel to test | 07:43 |
| fabbione | it has some fixes that might affect your problem too | 07:43 |
| braddr | can test at your whim | 07:46 |
| fabbione | braddr: cool.. i am uploading the image right now | 07:51 |
| fabbione | http://people.ubuntu.com/~fabbione/braddr/boot-sparc64.img | 07:54 |
| fabbione | go and destroy :) | 07:55 |
| braddr | ok, I'm assuming that's a tftp boot image.. grabbing... | 07:58 |
| fabbione | yeps | 08:02 |
| braddr | booting now.. fingers crossed. | 08:12 |

| fabbione | thanks | 08:14 |
| braddr | yup, sorry it didn't work. | 08:14 |

| fabbione | hey tmarble | 05:15 |
| tmarble | fabbione: hello! did you get some good rest? | 05:17 |
| fabbione | tmarble: yeps.. | 05:18 |
| fabbione | tmarble: do you think you can ask something for me to the Niagara people? | 05:18 |
| tmarble | i'm working on UbuntuSPARC today | 05:18 |
| tmarble | absolutely | 05:18 |
| fabbione | i noticed this during the POST: | 05:18 |
| fabbione | 0:0> $somepost message | 05:18 |
| fabbione | and on another machine | 05:19 |
| fabbione | 1:0> $somepost message | 05:19 |
| fabbione | notice the diff at the beginning | 05:19 |
| fabbione | 0 and 1 | 05:19 |
| fabbione | if you do poweron and console at sc> | 05:19 |
| fabbione | you get too see the post | 05:19 |
| fabbione | what is the difference between 0:0 and 1:0 ? | 05:19 |
| fabbione | is it the booting core? | 05:19 |
| tmarble | is one machine a T2000 and the other a T1000? | 05:20 |
| fabbione | because once you get to OBP, you always see {0} ok | 05:20 |
| fabbione | they are both t2000 | 05:20 |
| fabbione | 1:0 -> 4 cores | 05:20 |
| tmarble | hrm... dunno... I'll check | 05:20 |
| fabbione | 0:0 -> all the others | 05:20 |
| fabbione | it might be a coincidence | 05:20 |
| fabbione | it might be a case... | 05:20 |
| fabbione | i am curious to understand the meaning of the diff | 05:20 |
| fabbione | same OBP version (4.19..)( | 05:20 |
| tmarble | i'll ask | 05:21 |
| fabbione | thanks a lot | 05:21 |
| tmarble | fabbione: in chatting with doko yesterday I was under the impression that gcc-4.1 was in dapper (but I can't find it now..) | 05:26 |
| tmarble | should I wait for edgy (to do gcc-4.1)? | 05:26 |
| fabbione | tmarble: apt-get install gcj-4.1 ;) | 05:26 |
| fabbione | i was told today the exact same thing | 05:26 |
| fabbione | tmarble: i also checked that HUGETLB thingy, you were right.. it's going to be enabled in the next kernel release | 05:27 |
| tmarble | great... as far as that goes I have an idea on how to check for similar things before you respin | 05:27 |
| tmarble | I'll check my favorite config files and do a diff against the dapper config and then eval which (missing) things might be nice | 05:28 |
| tmarble | what's your policy on kernel updates -- can that happen in dapper or must it wait for edgy? | 05:28 |
| tmarble | FWIW you are going to want HUGETLB on i586 and amd64 platforms as well | 05:28 |
| fabbione | they are enabled afaik | 05:29 |
| === tmarble haven't checked (sorry for the noise) | ||
| fabbione | if they are not... i don't really care ;) | 05:30 |
| fabbione | x86* is junk anyway | 05:30 |
| tmarble | yeah, but a fair number of folks use them ;-) | 05:31 |
| fabbione | oh so do i.. they keep my feet and coffee warm :) | 05:32 |
| tmarble | my coworker Dave Dagastine had a great blog yesterday (I was going to blog about, but ran out of time....) | 05:33 |
| fabbione | url? | 05:33 |
| fabbione | if only the t2000 was not this noisy i would have turned it into my workstation | 05:33 |
| fabbione | with 3xPCI-E gfx's | 05:33 |
| tmarble | http://blogs.sun.com/roller/page/dagastine?entry=sun_java_se_and_sun | 05:34 |
| tmarble | It was picked up by JavaLobby: http://www.javalobby.org/java/forums/t73547.html | 05:34 |
| fabbione | eheheh | 05:35 |
| tmarble | I'll as the Niagara2 guys to work on the fans ;-) | 05:35 |
| tmarble | s/as/ask | 05:35 |
| fabbione | eeheh | 05:36 |
| fabbione | but i am really serious.. i was considering doing it | 05:36 |
| fabbione | for a 6 head workstation | 05:36 |
| fabbione | (now x64_64) | 05:36 |
| tmarble | with Xinerama? | 05:36 |
| fabbione | try to imagine a machine like that with 32 CPU and 32GB of RAM for development ;) | 05:37 |
| fabbione | yeah i am using xinerama | 05:37 |
| fabbione | http://people.ubuntu.com/~fabbione/office/ | 05:37 |
| fabbione | this is still at 3 heads + some extra monitors | 05:37 |
| tmarble | listen, I think it would be neat, but (and this is not a criticism of you) ... I don't think you can type fast enough to make the T2000 sweat! | 05:37 |
| fabbione | ahahha | 05:38 |
| fabbione | no, but i can make it sweat when building/debugging ;) | 05:38 |
| ajmitch | daily archive rebuild? | 05:38 |
| fabbione | ajmitch: hmmm with 32 CPU that would take about... | 05:39 |
| fabbione | 28 hours probably | 05:39 |
| fabbione | but yeah.. it's doable | 05:39 |
| fabbione | it takes 36 hours with 24 cpu | 05:39 |
| fabbione | so make your math | 05:39 |
| tmarble | umm, wow, I think you are going to need some flat panel screens! | 05:39 |
| fabbione | tmarble: are you going to ship me some? ;) | 05:40 |
| fabbione | i really need some more sparc/desktop gear | 05:40 |
| tmarble | well, it turns out I'm trying to get a SunBlade 2500 to pretend to work with UbuntuSPARC at the moment | 05:40 |
| fabbione | yeah but i am really looking to something i can test on a daily base | 05:41 |
| fabbione | vnc doesn't cover all i need to test | 05:41 |
| fabbione | sooner or later i will have to go and kiss some feet at SUN dk i guess | 05:44 |
| fabbione | they already hate me for other reasons... ;) | 05:44 |
| tmarble | hmmm not sure I know anyone in the dk office.... | 05:45 |
| fabbione | nah it'so | 05:45 |
| fabbione | it's ok | 05:45 |
| fabbione | don't even mention my name to them ;) | 05:45 |
| fabbione | nothing personal with them, but they did get lost in paper work when i was trying to get them to install a used e10k i bought for my ex company | 05:46 |
| fabbione | so i just installed myself | 05:46 |
| tmarble | well, I'm guessing you got some of your toys from them ;-) | 05:46 |
| fabbione | not really.. i used to buy them used | 05:46 |
| fabbione | anysystem.com ;) | 05:47 |
| fabbione | oh and i also got linux runnning on the e10k | 05:47 |
| tmarble | I see... I understand now.... (the whole used/grey market thing makes certain people go nonlinear) | 05:47 |
| fabbione | at that time it was really a massive operation.. but it was working fine ;) | 05:47 |
| fabbione | yeah i know.. but the company was too small to buy new metal | 05:48 |
| fabbione | so we were buying support | 05:48 |
| tmarble | that's pretty amazing... the e10k is actually one of the nicest SPARC architectures we've had | 05:48 |
| tmarble | getting the crossbar to behave in linux must have been, umm, interesting | 05:48 |
| fabbione | my secret dream is to play with the e25k | 05:48 |
| fabbione | and get one at home (together with a mini nuclear power plant) | 05:48 |
| tmarble | hehe | 05:48 |
| fabbione | http://people.debian.org/~fabbione/e10k/debian_on_e10k.txt | 05:49 |
| fabbione | i still have the "how i did it" | 05:49 |
| tmarble | wow | 05:50 |
| fabbione | i am pretty sure as of today most of the SMP issues are gone | 05:51 |
| fabbione | but i don't have access to it anylonger | 05:51 |
| fabbione | and i am not in a very good mood to travel 200km to play with it ;) | 05:51 |
| tmarble | the niagara stuff is in many ways more apropos now | 05:54 |
| fabbione | yeah | 05:54 |
| fabbione | i agree | 05:54 |
| tmarble | do you have any idea how much space is required to mirror all components of dapper? | 05:54 |
| fabbione | it depends what you want to mirror | 05:55 |
| tmarble | I've got lots of machines to install and I'm only getting 152 KB/s from http://us.archive.ubuntu.com | 05:55 |
| fabbione | in terms of arches and sources | 05:55 |
| fabbione | ask John Jonson or Greg Onufer | 05:55 |
| tmarble | i386 amd64 sparc | 05:55 |
| fabbione | afaik they have a local mirror inside sun | 05:55 |
| tmarble | ah... ok | 05:56 |
| fabbione | 195.22.207.161:/srv/mirrors/ubuntu | 05:56 |
| fabbione | 168G 147G 13G 93% /mirrors/ubuntu | 05:56 |
| fabbione | this is *everything* | 05:56 |
| fabbione | 6 arches | 05:56 |
| fabbione | + sources | 05:56 |
| fabbione | for all releases | 05:56 |
| fabbione | (including warty that should disappear soon) | 05:56 |
| tmarble | so maybe 50 GB for dapper? | 05:56 |
| fabbione | probably.. | 05:57 |
| fabbione | i am not even sure there is a mirror script to grab only one release | 05:57 |
| fabbione | braddr: ping? | 07:02 |
| braddr | ping | 07:45 |
| === braddr reads a bit of scrollback.. why bother with the t2000 as a desktop box.. get a cheap x86 with multi-heads and run everything over xterms / remote x | ||
| fabbione | braddr: hey dude... | 08:42 |
| fabbione | how complex would it be for you to arrange access to your t2k for me? let say i need alom access and be able to slam a boot.img on the tftp server? | 08:43 |
| fabbione | braddr: take your time to figure it out and send me an email in case... | 08:45 |
| tmarble | fabbione: I have an answer for you | 09:06 |
| tmarble | This is a convention in POST to designate the core and strand (thread). | 09:07 |
| tmarble | Niagara 1 has 8 cores with 4 strands (threads) each. | 09:07 |
| tmarble | core:strand (thread) | 09:07 |
