By the way---I'm autocrosser at ubuntuforums.org----

<note> All it seemed to do is reload all my w/u--unsure if it changed anything else.

Welcome, autocrosser, nice to see you here.

Greetings & glad to finally talk to everyone here. I lurked around for quite a while---normally have too much work with Ubuntu to chat much of anywhere else. We are at a bit of a lull right now--the new Xorg still won't work with the restricted Nvidia drivers & the alpha seems to be working very well---waiting for the rewrite of network manager. Started crunching SETI late in Oct 1999 (Blue/White 300mhz G3) & do use a Pent D 3.4 for my Linux machine.

I think i have the optimized application installed.  What should
i look for in messages that will tell me if i do or don't ?

[Fivestar Crashtest]

When BOINC starts up, I think there is a "found app info xml using anonymous platform" message.  But even if there isn't, then you will know for sure from the messages in your results- when you look at them on the internet, they will show there, when you select results and then task id.

OK, got this online:

        What does it tell us ?

It says the host is still running the stock application.

The project is about to go into its weekly downtime, but after it is back up, go to the Top Computers list from the home page, look for a host running Linux and check some of that host's results to see what the optimized app puts in. It is actually quite similar to what a Windows optimized app has:

Optimized SETI@Home Enhanced application
Optimizers: Ben Herndon, Josef Segur, Alex Kan, Simon Zadra

Can someone point me at a simple explanation of
how to install a linux version of SETI/BOINC ( preferably an optimized app )
 on my computer ?  ( AMD Turion 64 SSE2 )

My way is to download the Linux version of BOINC from the BOINC download page.  Move the file you download into the home folder.  Go to Accessories, open a terminal and type into it

sh boinc*

Then type

cd BOINC
./run_client

open another terminal (if you open one in a tab, it will already be in the BOINC directory) and type

./run_manager

Then you will have the gui, which works like the one in windows and you can attach to Seti.

I let it download a work unit or two and set it to no new work.  After the first two are done, then I report them and stop boinc by going back to the first terminal and typing

CTRL C

I close that terminal out and stop the boinc manager too.  I download my optimized app.  With your AMD, you want a generic sse2 linux app, 32 bit if you are using 32 bit linux.  If you are not, you will have other issues, but I can help you with those.

Go to the projects folder in your BOINC folder and remove the Seti app there.  Extract the optimized app and it's app info xml either into it's own folder and copy it into the project folder or extract it directly into the project folder, ARK is pretty easy to figure out. 

When you start BOINC up again in the terminal the way you did before, then you should be crunching with the optimized app. 

A lot of guys like the BOINC with Synaptic Package manager, but I don't.  I like to run BOINC from the home folder.  Hope this helps and welcome to Linux and Optimized Seti.

      Hello Pam:

                 I am ( now ) running 64 bit ubuntu and cannot for the life of me
get an optimized application to run. Any suggestions ?

Not long ago when I last set up Ubuntu on my new AMD laptop, I could not get the 64 bit 5.10.28 BOINC to run anything.  It would say the work unit was suspended, even though I had not set BOINC to suspend anything.  I couldn't find anywhere anyone else experiencing this problem, but I fixed it by switching to Crunch3r's 64 bit 6.1 BOINC client.  Let me hunt down the link for that...

http://calbe.dw70.de/boinc_red.html

I changed the name of the file from boinc-client to boinc and dropped it into my boinc folder and everything was cool.  I've been using this on all my 64 bit Linux boxes.

Unless i'm missing something ( very possible ) i've got the optimized version

You got it.  You are optimized.

[TouchuvGrey]

i think i'll stick with this one 2.4_Linux64_kernel_2.6_generic_SSE2.tar.bz2
that i got on the downloads page for a while and see how it goes. Though
i'm always looking for something crunchier to run.

I'm puzzled here, 64 bit ubuntu, optimized application
RAc is now appx 211 on that machine.

211.62     21,327     AuthenticAMD
AMD Turion(tm) 64 Mobile Technology ML-34 [Family 15 Model 36 Stepping 2]    Linux
2.6.20-16-generic

identical machine not 6 feet away running XP Pro SP2 is

AMD Turion(tm) 64 Mobile Technology ML-34 [x86 Family 15 Model 36 Stepping 2]    Microsoft Windows XP
Professional Edition, Service Pack 2, (05.01.2600.00)

        I would have thought linux would be faster. Both machine on and permitted to run BOINC
24/7. Can anyone offer any insight or suggestions here ?

It takes RAC usually 6 to 8 weeks to level out. How long are yours running ? Did you compare runtimes of single work units having very close/identical Angle Ranges (AR) ?
