Seti@home is no more!
It has ceased to be!
It's expired and gone to meet 'is maker! It's a stiff! Bereft of life.
It rests in peace!
If you you remove the mainpage link it can push up the daisies!
Its Computational processes are now 'istory! It's off the twig! It's kicked the bucket, 'e's shuffled off its mortal coil, run down the curtain and joined the bleedin' choir invisibile!!
THIS IS AN EX-SETI@HOME!!

They found extra-terrestrial life at last? :-?

Alien search merges with other home projects (http://www.nature.com/news/2005/051212/full/051212-10.html)
"SETI@home is getting a boost in computer power.
Declan Butler
SETI@home, a downloadable screensaver that lets the public donate their unused computer time to the search for extraterrestrial intelligence, switches off today. But it is not going away: it is simply joining forces with similar distributed-computing projects on topics from climate models to cures for diseases. The move should boost the number of users, upping the computing power available to search for messages from alien life.
About a dozen projects are now signed up to a common software system, so that they can pool volunteers' computer time and use it more efficiently (see 'All for one'). As a result, each project should get access to more users, more of the time."
"Scientific progress goes BOINC
The Berkeley Open Infrastructure for Network Computing (BOINC) platform will allow SETI@home to evolve, using data beamed directly from different telescopes, including ones in the Southern Hemisphere, and looking at a wider radiofrequency range. "We designed BOINC to let us do the things that we want to do in the future," Anderson says, including rolling out faster and more complex software."

The link on the left should be http://setiathome.ssl.berkeley.edu/
I pm'd Wayne about it a while ago but just kept forgetting to see if he'd changed it. Looks like he might've forgotten :-)

Everyone knows that if you want to make contact you need the following:
· 1x 80's LCD computer
· 1x old record player
· 1x spoon
· 1x umbrella
· 1x coat hanger
· Some rope
If you ask me, RC5 and SETI have deeper, more sinister intentions at heart. You carry on believing they're for beating all other computer teams or finding aliens.
I prefer to think the CPU time is being used to test cryptography for commercial gain, military defence and calculating protein-folding for sinister new bio-weapons.
And let's not forget that Skynet in Terminator 3 was revealed to be a distributed computing program!

Hum,
The link on the left should be http://setiathome.berkeley.edu/team_display.php?teamid=33303
-
There is no link on the left anymore.
When did that happen?
-
That's strange, with my old mobo and OS I couldn't get the BOINC client to work, but since upgrading my hardware I seem to have no problems.
Now if only they can iron out the computing errors with the Enhanced Work Units, everything will be sweet. A computing error after 6 hours kind of sucks. On my machine the enhanced units are taking a fair amount of time to compute (about 6 to 7 hours), so I reckon on a modest system like the Sempron I had before, these times must be heading to the 12 hour mark at least :-o
-
I have a feeling we'll find out in 10yrs time that what you lot were computing was not search algorithms for extra terrestrial communication attempts.
Same goes for RC5, but at least SETI had a more interesting 'decoy story'...
EDIT: Oh, I've already spouted off on the conspiracy theory. Sorry.
:-D

----------------------------------------------------------------
You're joking, right?
-
@X-Ray
Good to see you're back on the project again :-)
With my Sempron 2600+ I average about 3 hours, but the occasional one can easily reach 6 hours.
Although the one that's being done now is 6 hours 55 minutes in and it's only done 54% :-o
-
@ Vincent
Yup, its good to put this new PC to some use now.
When you say 3 hours are you talking about the 4.18 standard units or the 5.12 enhanced units? Because I do the 4.18 units in about 2.5 hours but the enhanced 5.12 ones are definitely more than 4 hours on my setup. This is a dual core AMD 4200, so essentially it is like two CPUs at 2,2gHz. I would have thought that beats the Sempron. What units are you processing? I am being given a mix of 4.18s and 5.12s.
Edit: each core is assigned a separate work unit, and it does them simultaneously. Sometimes one core will be doing a 4.18 and the other will do a 5.12. If I display the graphics for both, I get two 3D graphs and the 5.12 will say 'Enhanced' whereas the 4.18 is the same as it always was.
-
Okay scratch the enhanced questions, I checked your results and you are doing the mix too. You are averaging the same processing time for the standard units as me (about 7,000 to 8,000 sec) but I have a slight edge on you with the enhanced units: my range is 16,000 to 33,000 sec with most of them being at the 21,000 mark whereas yours is more like 19,000 to 35,000. It seems to me that your Sempron is not much slower than one core of my CPU.
My higher average credit comes down to a 2 cores vs 1 performance difference (unless I have calculated wrong)
Edit: just saw that some of those results of yours for standard units were 14,000 so the Sempron is definitely slower.
-
Thankfully I read your second post before answering :-D
Not much difference between your 2.2GHz and my 1.8GHz then.
I would've expected a bit more out of 2.2GHz, but then it could be different to translate as you're running dual core instead of one 2.2GHz chip.
Interesting all the same :-)

Forgot to say I run mine constantly in the background when the PC is on.
About 12 hours of work gets done a day, about 7 or 8 of that is probably when there's a lot of other stuff going on.

Exactly. If it was taken seriously there would be funding for it.
I have a very open mind but am sceptical about the power of a large group of computers under control of one being used for a single task dictated to by a single organisation.
This talk of the program running on two seperate cores of the CPU at the same time is plain devious in my opinion.
Whilst I have a raised eyebrow about the SETI stuff I am more or less convinced that RC5 was a commercial venture to prove banking and military encryption technology before being sold on the mass market: after all, if the world cannot beat RC5 what hope have they of the 128-Bit SSL sold by some companies for websites?
Maybe I'm barking up the wrong tree but if you consider yourself as open minded as to believe extra terrestrials are trying to communicate with light-velocity particles (when it takes a year for photons to travel to our nearest planet harbouring neighbour) then surely it is prudent to believe that you could also be a guinea pig. Just like the millions who are unwittingly under the control of spyware, trojans, worms and botnets.

----------------------------------------------------------
I suggest you look up what dual core really means and how it is supported by the various OSes in current use.
When I raytrace with Cinema4D it uses both cores much the same as Seti does: one core raytraces the top half of the image and the other one raytraces the bottom half. The only difference is that Cinema is working on separate parts of one 'object' while Seti is using two objects. The user can assign what percentage of 'resources' Seti uses. I can choose how many cores it uses, and what percentage of that core it uses. There is nothing underhand about it. So where is the chicanery that you seem so anxious to bring to our attention?
Futhermore do you really think that the clandestine use of millions of computers would go undetected when the data sets being analysed are downloaded onto the host computers and are freely available to analyse? If this was all a big conspiracy then how come third party applications designed to crunch these sets in a more optimised way are being used with no reproach?

@ Blobzie and Vincent
Now that we have these 5.15 units, there seem to be more errors, even more than 5.12. I just stopped one unit that had been going for 12 hours and was stuck on 98%. On a single core machine, that will go forever and you'll get no progress with Seti if you don't stop it.
Just thought I'd remind you to check more often on the progress of your units :-)
-
Hum,
tnx for the heads up...
But no real problems here...
-
Are you doing any 5.15s, B?
-
Every day or so I have a quick gander at Boinc to see what type it's doing.
Not an error like you've had, but some of my results have been completely off.
God knows how I got that client error on the 12th May though, maybe that was something like this new one.
-
@X-ray
>>doing any 5.15s?
Hum,
Yeah, i have only the best (er, enhanced) version running...
http://setiathome.berkeley.edu/team_display (http://setiathome.berkeley.edu/team_display.php?teamid=33303)
-
And how long do your 5.15s take compared to the 5.12s?
(Can't see which ones are 5.12s and which ones are 5.15s in your list, they both show as enhanced units)
-
Hum,
The ones I've got uploaded just now all seem to be on average about 9 hours long...double the time i spent (on average) of the last load...
-
:laughing:
Hah... you trainspotters!

@ Hyperspeed
You seem to have an affliction that reduces your ability to contribute anything worthwhile to this thread.
In the beginning it was of mild amusement, similar to the discovery of a multicoloured bird dropping on the pavement.
But now it is taking on all the charm of a donkey repeatedly braying at his own reflection in the pond.
If you want to be the source of a few giggles, I can quickly arrange it...I'll slap an ode on your arse ;-)
-
I'm sorry X-ray... I was just teasing.
Maybe I'm a gentleman scorned... I wrote blobrana an insightful and ponderous scientific memo and she ignores it...
In the meantime, with my memo still in the mailbox, she searches for messages from wrinkly aliens from Uranus.
*sob*
-
Hum,
i didn't ignore it. You mean didn't get my telepathic message?
(i`m a bit busy just now to indulge myself with your insightful and perponderous scientific memo, but i`ll get back to dealing with you)

PlayStation 3 tackles world ills (http://news.bbc.co.uk/1/hi/technology/5287254.stm):
The spare processing power of Sony's PlayStation 3 (PS3) will be harnessed by scientists trying to understand the cause of diseases like Alzheimer's.
Sony has teamed up with US biologists who already run the distributed computing project, folding@home (FAH).
The project harnesses the capacity of thousands of PCs to examine how the shape of proteins, critical to most biological functions, affect disease.
FAH say a network of PS3's will allow performance similar to supercomputers.
With 10,000 machines joined together the researchers calculate they should be able to do a thousand trillion calculations per second.
If that was achieved it would be nearly four times as fast as the world's most powerful supercomputer, IBM's BlueGene/L System, capable of 280.6 trillion calculations per second.
Wonder how long it'll be before there's a BOINC port ;-)
-
Scientist 1: Yes! YES! Y E S! Eureka! Let's chain 10,000 Playstations together so we can calculate stuff!
Scientist 2: No.
