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.

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.

"...This talk of the program running on two seperate cores of the CPU at the same time is plain devious in my opinion..."
----------------------------------------------------------

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  :-)

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.

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...

@ 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)
