01:15 <Darm0k> hi

01:16 <Darm0k> i am asking for some thing

01:16 <Darm0k> if i start the gpu app my linux xorg is 99 percent in stress

01:17 <Darm0k> somebody said its because they share opengl and cuda, adn thats not very good, so my system runs on ubuntu server with unity and i want to start a GPU boinc app only if the screensaver has activated

01:18 <Darm0k> because the screensaver doesnt need anything guimatics, its just blank

01:18 <MTughan> First of all, what GPU do you have?

01:18 <Darm0k> i got a geforce 220

01:18 <MTughan> And what drivers are you using?

01:19 <Darm0k> 313.09

01:19 <MTughan> But the Nvidia official drivers and not Mesa or Nouveau, right?

01:20 <Darm0k> i blacklisted those two

01:20 <Darm0k> kernek 3.5

01:20 <Darm0k> i tried to do some crumber nunching with the gpu

01:22 <Darm0k> my cpu is working for the company constellation

01:22 <MTughan> Well, a GT 220 isn't much to crunch with, but I'm not exactly sure what else to ask as I haven't tried GPU computation under Linux at all. I think you'll have to wait for someone with a big of experience in that.

01:23 <Darm0k> well even my television Set Top Box(dreambox) and my Router (fritz box) having a job

01:24 *** simone__ has joined #boinc

01:25 <Darm0k> i wish you can set up boinc to not use above a temperature

01:25 <MTughan> I believe there is some work towards that end, but it doesn't exist ATM.

01:26 <Darm0k> e.g if core is 55 degrees it should idle a core or two

01:27 *** simone_ has quit IRC

01:28 <PovAddict> you can hack together something to do that externally

01:29 <PovAddict> query CPU temperature every second, pause BOINC via boinccmd if temperature exceeds your threshold

08:52 *** zanzacar has joined #boinc

08:55 <zanzacar> can anyone help me with install boinc on a headless terminal and configuring it? I have try once every few years and always seem to fail

08:56 <zanzacar> i guess i always get it install but I don't know what the next step is really

08:58 <dddh> zanzacar: you need to create an account

08:58 <zanzacar> dddh: ok sounds reasonable, through the website or through the terminal?

08:58 <zanzacar> I am on a headless server

08:59 <dddh> did you choose a project you want to participate?

08:59 <zanzacar> dddh: no not yet

08:59 <dddh> http://boinc.ssl.berkeley.edu/projects.php

08:59 <Romulus> Title: Choosing BOINC projects (at boinc.ssl.berkeley.edu)

08:59 <zanzacar> I am there right now

09:03 <dddh> after you will choose and register at project website you'll need to attach your server

09:05 <dddh> account key: "boinccmd --passwd `cat ~boinc/gui_rpc_auth.cfg` --lookup_account http://einstein.phys.uwm.edu/ your.email@gmail.com your_password"

09:05 <Romulus> Title: Einstein@Home (at einstein.phys.uwm.edu)

09:05 <dddh> and "boinccmd --passwd `cat ~boinc/gui_rpc_auth.cfg` --project_attach http://einstein.phys.uwm.edu/ account_key"

09:05 <Romulus> Title: Einstein@Home (at einstein.phys.uwm.edu)

09:06 <dddh> zanzacar: headless server means no GPU?

09:08 <zanzacar> dddh: no monitor

09:08 <zanzacar> dddh: i login from another computer so I don't have a graphical user interface

09:08 <zanzacar> so I can donate my GPU all the time practically since everything I do is text based

09:09 <dddh> what kind of GPU?

09:12 <zanzacar> boinc says no usable GPU's found

09:13 <dddh> it will use your CPU then

09:13 <zanzacar> ya that is what I was thinking

09:14 <zanzacar> alright so I registered for virtual-prarie

09:16 <dddh> account key: "boinccmd --passwd `cat ~boinc/gui_rpc_auth.cfg` --lookup_account http://vcsc.cs.uh.edu/virtual-prairie/ email password"

09:16 <Romulus> Title: Virtual Prairie (at vcsc.cs.uh.edu)

09:17 <dddh> attach: "boinccmd --passwd `cat ~boinc/gui_rpc_auth.cfg` --project_attach http://vcsc.cs.uh.edu/virtual-prairie/ account_key"

09:17 <Romulus> Title: Virtual Prairie (at vcsc.cs.uh.edu)

09:18 <zanzacar> I keep getting Authorization failure: -155

09:20 <dddh> do you use the same password you used to register your account?

09:20 <dddh> try to "cd ~boinc" first

09:22 <desti_T2> use the weak account key from you profile

09:23 <dddh> desti_T2: seems like -155 is local authorization error

09:24 <zanzacar> desti_T2: I used the weak but I was having issues with the first of the to commands

09:25 <desti_T2> start boinc directly

09:33 *** simone__ has joined #boinc

09:34 <zanzacar> i tried that still got authrization failure

09:35 <zanzacar> i tried changing the permissions of the gui_rpc_auth.cfg file

09:35 <zanzacar> but that didn't help either

09:37 *** simone_ has quit IRC

09:37 <dddh> hm

09:37 <desti_T2> what are you doing? there is no need to use the gui ever

09:39 <zanzacar> I wasn't trying to use the gui I was trying to enter the commands as recommended.

09:39 <zanzacar> desti_T2: how would you recommend I attach my client to the project/

09:39 <dddh> zanzacar: "cd ~boinc"

09:39 <zanzacar> dddh: tried that too it didn't work

09:40 <dddh> from boinc home you can run "boinccmd --project_attach http://vcsc.cs.uh.edu/virtual-prairie/ account_key" without password

09:40 <Romulus> Title: Virtual Prairie (at vcsc.cs.uh.edu)

09:41 <zanzacar> ok that worked

09:44 <zanzacar> so now when I type in boinc it says it is already running

09:44 <zanzacar> so I guess it all worked alright but I don't know what is going on with it since I am guessing it is running the background

09:45 <dddh> try "to tail -n600 -f /var/log/boinc-client.log"

09:46 <zanzacar> there isn't any log file.

09:46 <dddh> oh

09:46 <dddh> what is your OS?

09:48 <zanzacar> ubuntu 12.10

13:03 <eikelmt> I am running fedora 18 - 64 bits and have problems running boinc and need help

13:03 <eikelmt> the problem has been around since I used FC17

13:04 <eikelmt> client is running fine

13:04 <eikelmt> boincmgr will not connect when it is started from the menu

13:04 <eikelmt> if I stat it from term windows as root, it will work fine

13:04 <eikelmt> I am out of ideas

13:05 <PovAddict> never never ever never ever run graphical apps as root

13:05 <eikelmt> so pls help me

13:06 <eikelmt> i am not

13:06 <eikelmt> i just did it during my troubleshooting

13:06 <PovAddict> oh man, looking at the backlog i see the same problems happening again and again, when will BOINC ever improve its usability?

13:08 <Tank_Master> submit a patch to rom?

13:09 <PovAddict> well some are packaging issues too

13:09 <PovAddict> anyway I have no time for BOINC development, I have my fingers on a dozen other things

13:09 <eikelmt> how can i start boincmgr as user boinc to see if that works

13:19 <RomW> @zanzacar, gui_rpc_auth.cfg probably has a line feed after the end of the password.  Try trimming the returned string.

13:20 <PovAddict> common problems I have seen:

13:21 <PovAddict> - the boinc client installed into /usr/bin, so users type 'boinc' and make a mess: the client is already running due to the start-on-boot script and/or the user just littered his $HOME with BOINC's state files

13:22 <PovAddict> - gui_rpc_auth.cfg with permissions that don't let the user read it

13:23 <PovAddict> - boincmgr only looking for gui_rpc_auth.cfg in the current directory, so if you run it from a terminal it can't connect, while the DE's menu entry works because it sets the cwd appropriately

13:24 <Tank_Master> ugg, i hate it when the propt to ask to end all boinc tasks when exiting the manager gets put under the manager

13:24 <Tank_Master> so i cant click on it

13:24 <PovAddict> - or worse: the above + distro *doesn't* set the cwd properly in the menu entry, so boincmgr can't connect to the client even when launched from there

13:26 <Tank_Master> oh, RomW, ive noticed that the option in the windows installer 'Allow all users..." doesnt get remembered at the next install, but the path locations do

13:26 <PovAddict> - related to the first: users running 'boinc' (the daemon) with --attach_project, which is supposed to be for debugging, not the correct way to attach a project

13:28 <eikelmt> if I get it right, gui_rpc_auth.cfg has a flaw addinf a cr to the line?

13:28 <PovAddict> those options should be removed or at least not mentioned in --help... though ideally the daemon should be installed out of the $PATH so people don't run it manually at all

13:28 <eikelmt> because I do a cat on gui_rpc_auth.cfg, going to the advanced menu option adding computer and psw

13:31 <eikelmt> same shit when entering the psw in manually

13:31 <wdsmia> asks eikelmt to please watch his or her language… Thanks, your friendly channel op.

13:31 <eikelmt> sorry

13:31 <eikelmt> I am very frustaded and I miss the old seti app

13:31 <eikelmt> i have been coputing for seti over many years now

13:32 <PovAddict> the old seti app that ran a single project, didn't keep a local queue, and afaik didn't even know of multicores?

13:32 *** linuxthefish is now known as linuxthefish`

13:33 <Tank_Master> it was somewhat dual threaded

13:33 <Tank_Master> it could make use of a second thread part of the time

13:33 <RomW> There was a tool called setiqueue if I remember correctly that could do some of that stuff

13:33 <PovAddict> oh did it support running N apps on N cores at least?

13:34 <eikelmt> but it worked without any problems while boinc, which is a nice app when it is working , gives me problem each time

13:34 <RomW> I don't remember

13:34 <Tank_Master> no

13:34 <eikelmt> the client is working fine but not the boincmgr

13:34 <Tank_Master> only one app at a time, and wouldnt allow for running multible instances wither oorc

13:34 <Tank_Master> iirc*

13:35 <Tank_Master> boinc is far better than the seti classic app

13:35 <RomW> Hmmm, I thought I used a tool that would run multiple instances of the command line tool

13:35 <Tank_Master> despite how much we bitch about how much boinc sucks :P

13:35 <Tank_Master> well, i was refering to nativly, rom

13:36 <Tank_Master> there probably were tools for that

13:36 <RomW> Well people complained about the SETI app when it was in use too

13:36 <RomW> <shrug>

13:37 <Tank_Master> like there was a tool to make a server that would feed work to multible client on the LAN, so only one comp needed access to the internet

13:37 <PovAddict> when I started with SETI the website already had a big scary warning telling people to get BOINC instead, so I never got to see the classic app

13:37 <Tank_Master> i joined seti clasic on 01-01-'01

13:38 <PovAddict> fun task for new year

13:38 <RomW> @eikelmt, does the manager start in the same directory as the client?

13:40 <RomW> @Pov, the Linux version of BOINC has a requirement that it can be run from the current directory to handle being run on computational grids used by Universities using either Globus or Condor

13:41 <PovAddict> that's fine

13:41 <RomW> I think that requirement causes this other stuff

13:41 <PovAddict> but it should be put into /usr/sbin, at least in distro packages, so that it's not in the $PATH by default

13:42 <RomW> or is rather the root cause of us not being able to fix the other issues on Linux

13:45 *** linuxthefish` is now known as linuxthefish

13:45 <PovAddict> RomW: I have seen every problem I listed in practice, from people asking in this channel, multiple times, sometimes several users hitting the same wall in the same day

13:48 <eikelmt> Romw: yes both of them is located in /bin and also in /usr/bin

13:49 <RomW> oh geeze

13:50 <RomW> @eikelmt, where is the data directory?

13:50 <eikelmt> but looking at ps -aux| grep boinc showes me /usr/bin

13:51 <eikelmt> data dir is /var/lib/boinc

13:51 <eikelmt> if I start boincmgr as root it is working

13:51 <RomW> okay, if you launch a terminal and cd into that directory

13:51 <eikelmt> I did that for testing

13:51 <PovAddict> cd /var/lib/boinc; boincmgr;

13:51 <RomW> what happens if you launch boincmgr from there

13:52 <eikelmt> just a sec

13:54 <eikelmt> the same , it will not connect

13:54 <RomW> hmmmm

13:54 <eikelmt> the owner of boincmgr is my user id but boinc client is owned by boinc

13:55 <PovAddict> that's correct

13:55 <RomW> okay, kill the already running boinc

13:55 <eikelmt> boinc mgr and gui is killed

13:55 <RomW> launch it from /var/lib/boinc

13:55 <eikelmt> i did

13:55 <RomW> and then launch boincmge from /var/lib/boinc

13:56 <PovAddict> RomW: that'll screw up permissions!

13:56 <RomW> oh?

13:56 <RomW> okay, don't do that

13:56 <RomW> then

13:56 <eikelmt> I launched boincmgr from var/lib/boinc

13:57 <PovAddict> the data files are owned by 'boinc'; running the daemon as a standard user will fail to write to those files and/or create user-owned files that the boinc user won't be able to access later

13:57 <RomW> what are the permissions on gui_rpc_auth.cfg?

13:58 <eikelmt> -rw-rw----. 1 boinc boinc     32 Jan  2 20:36 gui_rpc_auth.cfg

13:58 <eikelmt> sorry but what is the dot at the end of the perm

13:58 <RomW> are you part of the boinc group?

13:58 <PovAddict> ^ add that to the list of problems users keep hitting again and again

14:01 <eikelmt> Romw I am not member of the boinc group

14:02 <eikelmt> should I be?

14:02 <RomW> Well, add yourself to the boinc group

14:02 <eikelmt> ok

14:02 <RomW> I think so

14:03 <eikelmt> shall I then try to start boincmgr

14:03 <RomW> yup

14:04 <eikelmt> no cannot connect

14:04 <PovAddict> if you change your group membership, you have to log out of the desktop and log back in

14:05 <eikelmt> ok

14:05 <eikelmt> in the name of troubleshooting I can do that

14:05 <eikelmt> see you guys

14:05 <Tank_Master> gl

14:05 *** eikelmt has quit IRC

14:06 <PovAddict> "how can i get difference between 2 unix timestamps converted in seconds?" wow, some people...

14:06 <RomW> lol

14:07 <RomW> I didn't think Linux cached group memberships

14:07 <PovAddict> the list of groups is per process

14:07 <RomW> I thought that was read out of /etc/group each time the API was called

14:08 <RomW> hmmmm

14:08 <PovAddict> it's inherited to child processes

14:08 <RomW> learn something new

14:11 <PovAddict> the way it works for the main GID seems straightforward: login process forks, calls setgid, calls setuid (losing root privileges so it can't do set*id anymore), and exec's the shell or desktop env

14:11 <PovAddict> but I can't find how it works for the extra groups... *asks*

14:16 *** eikelmt has joined #boinc

14:18 <PovAddict> ah got it

14:18 <PovAddict> there's a setgroups() syscall to do the same as setgid but for supplementary group IDs

14:18 <eikelmt> guys

14:19 <eikelmt> BACK IN BUSINESS                                    THANKS

14:20 <eikelmt> Romw   PovAddict   thank you so much for your help'
