I think I have part of the answer here. It's just a matter of the server not taking no for an answer. I am the 8th one to get this work unit and in about 2 days it will be crunched and I will get no credit for it.

I think this is a different issue... that one is a bunch from one day. This issue is Maxwell 970/980 cards generating 80% invalids from any time.

I guess the MB CUDA just stresses the GPU more than AP or the Einstein code.

OK, I moved both 980s to my main machine. In doing so I noticed the elephant in the room that seems to have been overlooked:


I had one on a 525W named PSU and another on a 680W no-name, but I bet neither one could deliver the sustained ripple-free 14A the cards need. (Also NVidia has really pushed the reduced power requirements of the Maxwells... maybe to the point of "exaggeration.") Now that they are on the 1000W Azza Titan with the 86A 12V rail, all the work units are completing.

What make/model of PSU do you have Ryan?

how much CPU are you giving each MB?

0.4 on both. GPU util. usually about 78-80%.
(Edit: running with count=0.5 as they aren't very powerful.)

I'm having the same issue on two machines, this one (Win32) and this one (Win64). They are both generating hundreds of invalids.

* Both of them have GTX980s. (Hope this gets fixed or I've just wasted a lot of money. :^p )
* This happened running 100% stock on a fresh install of Windows with only the latest NVidia driver set (347.09), and continued once Lunatics with MB CUDA50 was installed.
* As indicated above, 32-bit/64-bit OS doesn't seem to make a difference.
* It doesn't seem to affect CUDA AP... the results are validated.
* It didn't affect E@H CUDA when I was running that. This host had zero invalids.

Here's a comparison of the bad result from mine and the good result from someone else of the same MB CUDA work unit. The others I checked also shows these excessive results. From watching them, they complete (sometimes long) before reaching 100% of course.

So this seems to be just an incompatibility in MB CUDA on Maxwells which is part of the stock code and hasn't been altered by Lunatics yet.

Hope this is of some use and if I can help out with any testing, etc. if there's a fix in the works please let me know... one of those machines is just a cruncher so I don't mind breaking it for a good cause. :^)

The "WOW" signal is anything but; it's an old, tiresome, overblown nothing. Nothing was recorded, as noted, so it's only a lump on a graph. It was never seen again and not from lack of trying. It wasn't confirmed by anyone else. Because of this, it also wasn't rigorously confirmed to be of distant extraterrestrial origin, either.

It wouldn't pass SETI@Home muster, and with SAH's fifteen years of accumulating a billion results there are probably thousands in there as good or better which did pass muster and still didn't amount to anything.

An atheist is someone who doesn't believe in any god or gods, an Agnostic is someone who doesn't claim to know for sure that any gods exist or not. A subtle difference. I think I'm a cross between the two. I'm damn sure that no Gods exist, but if I get incontrovertible proof that they do, then so be it. Yep 75% Atheist, 25% Agnostic.

Actually, you can be (and appear to be) 100% both. Atheist = lack of belief, and agnostic = lack of any claim of knowledge one way or another.

"Don't murder", "don't steal" and "don't bear false witness" is taken into account:

7. Treat others as you would want them to treat you, and can reasonably expect them to want to be treated. Think about their perspective.

It's not called the "Golden Rule" for nothing, you know. :^)

Also I'm predicting this is gonna end up in Politics.
48) Message boards : Number crunching : Update for contributors to GBT SERENDIP receiver - Cards obtained (Message 1616523)
Posted 20 Dec 2014 by Profile Mr. KevvyProject donor
There hasn't been any update from the SAH team in a long time on the Green Bank Telescope SERENDIP receiver, which will bring a second source of SETI@Home work online...

... So to anyone who contributed in the unofficial matching fundraiser here on March 20th of this year, the fundraised cards were finally purchased today. Your contributions made this project possible and were very much appreciated.

The delay was mostly due to the team evaluating the new NVidia offerings, ie the Maxwell cards such as the 980. In the end, they did what I hoped they would and stuck with the original requirement of the GTX780ti, most likely because this is what is being already used in the Arecibo SERENDIP receiver so is both proven and will provide consistency in results.

Hope there will be further updates in the near future. If they don't go into the News section I will try to post them here, if this thread doesn't go stale.

Nice... finally dry spell coming to an end (it will be difficult leaving E@H home though with the higher RAC!)

Two queries:

1) Is there enough storage (ie drive units) with this sudden amount of work? (Money burning hole in my pocket... heh.)

2) Is there going to be any Green Bank work mixed in, now or in the near future?

My avatar isn't in my profile, but if it were here it is enlarged:

It's the cover of this album.

I picked this for several reasons (aside from just liking it)... it's electronic and depicts a world dominated by computers, which pretty much happened, for us at least (one of the tracks, Computer Love, seems to predict social media and using one's computer to find partners.) And it was released in 1981 which when I started using computers and programming them at school, so is nostalgic; the computer is the old monolithic style with the integrated monochrome monitor and keyboard that I started with.

Just an idea but have you all ever considered trying one of the crowd funding site to get donations for the sole purpose of buying time on telescopes for the Seti project.

The upcoming Green Bank project will be dedicated time observing the Kepler Field. We're already going to be getting some prelim. data from it to crunch soon (I hope.)

"...developing a new splitter so we can start processing our Green Bank Telescope data..."

What the...? The receiver is done? Or is this just "interim" data from the test setup.

The last I had heard the team hadn't even settled on the GPU type, and that was only a week ago. If the receiver is well and truly built and we'll be getting Green Bank data finally (and long term) then this is wonderful news and I can finally splurge on new cards.

We are going to laugh and ridicule every new fusion concept right up to the one that works.

The laughter is an earnest requirement; ideally it should be loud enough that it is heard by bamboozled politicians about to throw more money their way.

I'm all for fusion research, but when groups start making the kinds of pronouncements I quoted, it sounds as though they are fleecing a public desperate for an alternative energy source to preserve its future. Or perhaps they just need a better press agent. :^p

This is yet another of a similar series of announcements this year from the 'secretive' 'Skunkworks'...

My suspicions are similarly suspicious for such grand claims with nothing of substance to believe...

All a game of funding?...

And there is this similarly dubious recent release which contained this absolute doozy:

Researchers ... say they have detected significant numbers of neutrons—byproducts of fusion reactions—coming from the experiment. This, they say, demonstrates the viability of their approach and marks progress toward the ultimate goal of producing more energy than the fusion device takes in.

Any bright middle-schooler can tell you this is utter twaddle... hundred-dollar tabletop Farnsworth fusors (including home-made) do fusion and produce neutrons, and have for seventy(?) years, and none of them have even approached an order of magnitude of closeness to breaking even. And theoretically, they couldn't no matter how they are designed.

I get the feeling that Tullio has a very low opinion of the work being done by the engineers and scientists under the employ of Lockheed/Martin in their quest for a working fusion reactor.

Tullio is skeptical and rightly so. Extraordinary claims require extraordinary evidence. Let's see a dozen independent analyses confirm that this device produces more energy via nuclear fusion than it consumes, and then we can break out the champagne and thank Lockheed Martin's scientists and engineers for saving humanity's future.

Until then, as you noted, it's yet another in a long line of failed attempts.

This is either the most amazing discovery in physics since, well, ever, which will force the rewriting of kinematics and other branches... or it's "Cold Propulsion." More confirmation and testing required. But definitely thanks for the heads-up. :^)

Due to relativity's mass/energy equivalence, emission of EM has "kickback" and a photon drive would work in under our current understanding of physcics, but to the tune of 150 megawatts per Newton of force (as a minimum; twice that if not reflected.) The Chinese team claimed 720 millinewtons which should require 108 megawatts of power. I rather doubt it was that high!

Posted 7 Sep 2014 by Profile Mr. KevvyProject donor
I think that the best argument against travel backwards in time ever being invented is the lack of time travelers from some unforeseen future turning up now at important events. Perhaps they are just good at hiding. :^)

Of course, there are the paradoxes as well. Once a time machine is invented, at at any time after that someone who didn't like time machines could prevent this from happening by going back in time and murdering the inventor(s).

Not a good idea for a septic tank system

Correct, but a great one for a building with wide pipes that won't clog.
