1) Questions and Answers : Unix/Linux : Graphics lost with sulphur (Message 21239)
Posted 13 Mar 2006 by old_user68986
Post:
I\'m currently just about to end phase 1 of my fifth complet simulation. The OS is Suse 9.3, and my hardware is an Athlon 2200 with 0.75G of memory. For this lastest run I\'ve been switched to the sulphur model. It\'s a bit slow, the average step time is over 6 seconds, but it\'s running fine. The only trouble is that I can no longer see the graphical output. I get the message \' Unable to attach to shared memory\' and my globe is just white.

Anyone any ideas please.

I tried it, and it works

Roger - that's me - is running boinc. There are two copies of globe.rgb on my system. One in /home/roger/slots/0 and the other in /home/roger/slots/1. Both files have read and write permission for roger and read permission for everyone else.

Yes, I can run TuxRacer, and the command
'glxinfo | grep rendering'

returns

direct rendering: Yes

I\'ve recently installed an fx5200-based graphics cards. After a lot of trouble I\'ve finally got X windows running again, but now when I try to run viz, I get the message ./globe.rgb: Permission denied.

Any ideas anyone?

Brilliant! found the rpm with the aid of Google- for Mandrake but works OK- at:
http://rpmseek.com/rpm-dl/libstdc%5C%5C6-3.4.1-4mdk.i586.html?hl=de&cx=0:-:0:1781028:0:0:0
Installed with the excellent Suse Yast.

viz now working - thanks for all your help

&gt; Your path should be /home/roger/<b>BOINC</b>/climate....
&gt; It can't be empty, because there are all the app and data folders in it.
&gt; The viz exe is named hadsm3viz_4.13_i686-pc-linux-gnu.
&gt;
&gt;Oops - now got the path right, it's a bit confusing, there are two project folders in my home directionary, both with a climateprediction sub folder - one of which really is empty.

Anyway, I've now found the right one, but attempting to run viz gets me:

roger@linux:~/BOINC/projects/climateprediction.net&gt; ./viz
./hadsm3viz_4.13_i686-pc-linux-gnu: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
roger@linux:~/BOINC/projects/climateprediction.net&gt;

You've be a great help so far - any suggestions for my next move?

Many thanks - I've now workded out the distinction between boinc and boinmgr and can happily start either program from the terminal. Also, as everybody says starting and stopping in Linux is no problem, provided you realise that boinmgr is really just a very limited window on the boinc client and, naturally, you have to start the client before the window can work. I'll follow up your suggested links to learn a bit more about all this.

One small, last problem, now I can follow the client in the terminal window I don't really need a graphical interface, but it would be nice to see it, particularly when, hopefully, I finally get to phase 3, but for some reason my /home/roger/projects/climateprediction.net folder is empty, so there's no viz executable file. I've yet to reach the end of December 1810, will the climateprediction.net files appear eventually?

&gt; 1. cd to home/your_name/BOINC/projects/climateprediction.net and type: ./viz
&gt; if you have 2 models on an HT machine, you can type the name of the wu after
&gt; ./viz: ./viz 2voi0_4542313545 for exemple. perhaps you'll need a library
&gt; called libstd6: you can download it on the internet in rpm.
&gt;
&gt; boincmanager and boinc are 2 differents programs. you can quit boincmanager
&gt; and boinc is still running. you can kill the boinc process without problem in
&gt; Ksysguard or in command-line. never noticed any problem doing it.
&gt; Killing boincmanager doesn't affect boinc. killing boinc while boincmanager is
&gt; running: you'll see boincmanager saying it is disconnected from localhost.
&gt; You can even boot or reboot your machine without paying attention to boinc or
&gt; boincmanager: boinc is stable in Linux and will not throw errors for that
&gt; reason (I reboot everyday on one of my dual-boot machine since several months
&gt; and never had an error: I use a little script place in the /.kde/autostart
&gt; folder to launch boinc automatically).
&gt; HTH.
&gt;

Many thanks
I'm fairly confident I'll now be able to get the graphics interface running - I need to, it's the only way I know how to tell which phase I'm in, and two of my XP runs (after nearly two weeks solid computation in each case) failed to progress beyond phase 1.

Unfortunately, I seem to have made a mess of shuting down CPN. I assumed that I could just shutdown Linux and the OS would handle BOINC, leaving everything ready to run again when I started-up Linux. What I seem to have done is to have killed boinc, as the boincmanger shows no work units and tells me I'm disconnected from the local host. I've been here before, and got round the problem then by re-installing boinc and starting again.

Is there a better of getting CPN running again?

I think I can solve this problem by suspending the running WU before shuting down Linux

Is this the right approach?

Thanks again for your help and patience.

After lots of problems with CPN running underXP, I\'m giving Lunix a go (Suse 9.1)

I downloaded the self-extracting file from Boinc, and ran sh boinc_4.43_i686-pc-linux-gnu.sh as instructed. It\'s by no means clear what to do next, but in reality everything seems to be, more or less done for you. I clicked on the boincmgr icon in my home directory window , added the CPN URL and my account ID and, eventually, I had an executing model. If it\'s as easy as this, I do wonder why the instructions can\'t make this clearer. Small moan aside, I\'ve two problems.

1 The show graphics button doesn\'t work

2 I don\'t know how to start and stop the BOINC manager gracefully, i.e. without risking the loss of work - I want to swwitch Linux off now and again. It\'s a dual-boot system and sometimes I have to run Windows.

I\'m very much a Linux newbie, but keen to learn.

Can anyone help please?
11) Questions and Answers : Windows : Two computer IDs and two WUs (Message 12982)
Posted 31 May 2005 by old_user68986
Post:
My computer was repeatedly running phase 1, instead of moving on to phase 2. Advised that this might be a hardware problem I defragged and checked my hard disk, and then ran the Prime95 torture test for 24 hours - without problems. I also reinstalled BOINC, using 4.43 the recommended client on the BOINC website.

Now I have two work units, one running and one suspended. Also, when I check my account it show two computer IDs, although there's definitely only one processor on my PC.

I suspect that when I finish the current work unit my PC will switch to the second work unit, and that this will be another phase1

Does anyone else have this situation, and is it a problem?

I've a 1.2GHz Athlon, with 256Mb of memory, running XP.
My first attempt to run phase 1 crashed after about 5 years, around 1815. My second attempt went to 1825, but instead of going on to phase 2, it started another phase 1. My third attempt has just done the same thing.

Can anyone suggest what might be wrong please?
