About SETI@home

SETI@home is the largest, most successful Internet distributed computing project to date. Launched in May 1999 to search through signals collected by the Arecibo Radio Telescope in Puerto Rico (the world's largest radio telescope) the project originally received far more terabytes of data every day than its assigned computers could process. So the project directors turned to volunteers, inviting individuals to download the SETI@home software to donate the idle processing time on their computers to the project.
More Details

Ok!

I've got the command line Linux version running on a 5 hourly cron job and I've stuck the Windows screensaver version on this machine so it can churn it out when I'm sleeping and at work.

I'll stick it on some other machines tommorow.

Come on SFDC let's get these CPU's pumping!

Thanks for the participation, nice stats hugo, how many machines / what time period is that for ?

Using the linux client you can run several instances by using seperate directories

So you can have a seti client running for each CPU Laughing Laughing

I registered (for the second time after a hard-drive crash which resulted in loss of the account details) on Fri Jun 14 17:18:42 2002 UTC. I can't remember exactly when I first signed on btw, that must've been in 99 maybe even.

I run SETI on about 8 machines, mostly Pentium-class machines (1 dual processor), not at all that impressive really. The two fastest machines run at approximately 750Mhz.

If it hasn't been too long, the data is probably still there, but I doubt they'll transfer the results to a new account.

I suggest you mail someone at SETI explaining the problem, maybe they can help.

I had to start from 0 after I lost my details, it didn't occur to me then that I could mail them.

Good luck.

As soon as I get my password through I'll join in, already downloaded and running the software - not quite as powerful as some of the kit being used tho (XP2100+, 512 meg, 40 gig) but it'll do.

Hey, I'll be the 8th member, oooooh exciting. Sad sad sad!

is it not possible to install seti remotely and without the annoying dos-box ?
e.a edit the win.ini file and enter a run=c:\seti\seticlient . If i do it like this all users will see a dos box with , as they see it , wierd blabla in it .
I have to authorization to use a network for seti . But it's not possible to install it on every system by going to sit behind the keyboard.

Is it possible to hide the process without aditional software being installed ?

heh it's time to compare the size of your work units gents!

Might stress test the new dual p4 2.8ghz pdc when no ones looking.

My 4hr wu was on a 1 cpu 2ghz so I should more than halve that.

ehmz you will do 2 wu in 4 hours because each wu takes 4 hour on each cpu .
4 hours for a Pentium IV 2 Ghz is terribly slow , my old athlon 2000+

A better link is (updated more frequently):

http://setiathome.berkeley.edu/fcgi-bin/fcgi?cmd=team_lookup&name=Security%2Dforums%2Ecom

I've joined with 2752 WU for the team...I used to do 10 WU per day between my three machines, but now it's down to 4-5 WU a day, due to SETI clashing with Soulseek.

I hope everyone is using the command-line version, it's much more efficient. If anyone needs any information on setting it up with SetiSpy, SetiDriver, or as a service under 2K/XP, let me know.

Pardon me for soundling like an idiot (usual thing round here anyway!) but is the command line version more effienct than the GUI version if it's left running in the system tray and the interface is ignored?

Cheers

Yes. It's far more efficient. Even if you don't open the GUI display up.

this may sound like a dumb question but if I'm halfway through processing a set of info and switch from the gui version to the cmd-line will it dump what I've sone so far and start over with another set?

Heh I always thought SETI stood for Speed and Endurance Testing Interface; a benchmarking program. I didn't know it could search for aliens?!? Wink

Seriously, I've always thought, as slightly as the chances may be, every little bit of CPU power helps.

Even if, in the end, it doesn't find any aliens at all, it's still giving the scientists some interesting insight, I guess.

i agree ....in the end ..who knows what's out there . If you don't search you will not find . Better search and not find then not searching and not finding anything .

The SETI project is very like space itself -- space is 99.7 percent void of content. 3.6 percent of known matter (to us) is centered in a mass volume of .00037 percent of known (by us) space.

In more understandable language, we are looking for a signal generated by an intellegent source in a vastness of garbled random noise. Looking for Nemo (the fish) in both the Atlantic and Pacific oceans would be considered much easier and more successful (but much less rewarding).

Although I myself have doubts about the success of SETI, I have never stopped supporting the project itself for the past twenty years. It is my firm belief that this is truly a noble and unselfless project taken on by the populace of mankind.

Surely if your that keen the same specced box with a customised linux install would give even better performance.

I was initially surprised that there are so few *nix users on that list but thinking about it most *nix users tend to stick it on an old slow box as is shown by the last entry on the list.

SETI@home is now up and running on my Linux box. The command line version is nowhere near as interesting to watch for half an hour as the GUI version tho Wink

System 1: XP2100+, 512meg ram PC2100 DDR, Windows XP Pro, SETI@home GUI version
System 2: Athlon 800, 392meg ram PC100, Slackware Linux 9, SETI@home CLI

Wonder which'll be faster? Laughing

Hobbies, what are they? Laughing

As a side note, it's interesting the different amount of time each unit takes to process, mine have varied from c. 6 hrs to c. 14 hrs. Suppose it depends on the current system workload but still, that sort of variation is a bit more than I would expect.

It does get updated it just takes a while. My first unit was done in 4 hours and it took about 24-36 hours for it to show on the site.
