Yea I hope it'll be back up soon too, I've got 36 results rdy for u/l which expire 2/7/14 18.34! And then a load more for 3/7/.
They were finished yesterday/day before & were only crunched late because I started another project & BOINC shunted the remaining WUs back. Fortunately I'd already stopped A@H from getting new WUs (stopping A@H for a couple of months or so to crunch R@H).


I have hundreds of results to upload. ;)

I've switch to Enigma@Home for the time being, but will switch back when the project comes back online.

Hey man, just a few then ;), what's the soonest expiry date?

Now, the webpage is in clean XHTML, but I also have to change the way of putting results there. So I have to rewrite it to PHP and create a database table for it and create also some scripts.

Ah ok, look forward to it :)

Maybe a month. I am not sure. I have to first rewrite the whole webpage with results.

Can't you just tag on the new results onto the end of the list?

And whilst your at it add the suggestions as per message 3068 by Bazso-DA :)

Well, I have been thinking about it. But there is a problem. This is really time consuming. If the Asteroids@home would do this, then everything about it I would have to do myself and the problem is that this is not my full-time job. So this is in a long term plan if my situation changes. But I would really like to start it.


Maybe you get some help from your team?
Would be great to bring 'Orbit' to a new life ...

As I understand it NASA have agreed to fund Orbit@home, it just hasn't got off the ground yet, indications were it would be this year........

Another method discussed for deflecting asteroids is a 'mass driver', where a craft is landed on an asteroid & it then digs up & fires off chunks of the rock into space in a direction that gradually pushes the rock away from earth.

But in my original post in the GPU thread I was under the impression that mikey meant immediately available options (I see I was wrong & that he actually said 'foreseeable future'.
But anyhow, as far as right now goes, AFAIK the only available options are nuclear missiles & the gravity traction method using a random but suitable satellite.

Well, the first question should be: how good works the detection of asteroids? How much time will be left before impact, how many objects fail to be recognised? Are there numbers available?
Who tracks the asteroids?


Well a quick google shows that NASA's doing a fair bit of tracking :)
http://www.jpl.nasa.gov/asteroidwatch/
I know that some amateur astronomers are also watching out, in fact a couple discovered the 1 that exploded over Russia recently.
Also NASA are trying to get other people involved http://www.topcoder.com/asteroids/tracker/

Crunching SETI isn't a waste (not waist ;) ), until we find ET, then maybe it is :P.

Also you mentioned that theirs only a very small chance of finding anything, true, but if we don't look we'll never find!

Re A@H GPU app, it was only released fairly recently (just this year IIRC), significant speed gains are being seen in new releases.

Btw I agree with you that Asteroid hunting should be funded by the UN, although I will say, AFAIK A@H isn't about finding new asteroids it's about better understanding the properties of the ones we do know about.
I believe Orbit@home was going to find new asteroids but that's still on ice atm.

In my opinion (but I'm sure many will disagree) finding ET is a hopeless and most importantly pointless quest. Even if we found a signal, why would it matter?
Hopeless? Well maybe the current method will turn out to be, but the only way to find out is to try.
Pointless?? I'm still staggered that anyone could think that at least! ;) Are you seriously saying that if you suddenly heard a news flash on TV that an ET
signal had been received, & conclusively proven to be so, that you wouldn't sit up & take notice??

Regarding what could happen after the 'wow' factor, well travelling to these places has never been on the cards (don't know where you got that from, maybe it would be centuries into the future).
But for now, if they're not too far away (say a few tens of light years or so) then it could be possible to communicate with them (if we thought it was safe to!), obviously this would incur lengthy communication times & so would have to occur over generations.
Naturally any signals in the 100s of LYs away & up would pretty much bar communications, but if they transmitted regularly we could learn a lot about them. Imagine what would be learnt of us by an alien species 1000 LYs away picking up our radio & TV signals in ~950 yrs time.

Regarding discovered exoplanets, we've only really just started the planet hunt, so expect many more discoveries over our life times, the rate of discoveries has & will continue to accelerate rapidly (e.g. Kepler has given a big burst of info there).

. So if you ask me, mapping asteroids is a lot more important than looking for ET.

Agreed, which is why most of my CPU crunching power has been on A@H since I found out about it last year ;). I do roam a little & other slower/part time rigs crunch SETI as I still like to contribute to my 1st DC project :).


Oh & you could of made your links clickable ;).

Mikey
Regarding asteroid deflection, your not entirely right about having nothing at all to deflect them.
Their are 2 that I'm aware of offhand, although they only cover a very small range of likely scenarios.
1 option is using a satellite as a gravity tractor, i.e. you fly the satellite very close to the asteroid & it's own gravity very slowly pulls the asteroid off course. This option of course would require significant advance warning & not too large an asteroid to be effective.
2nd option (controversially) are nuclear missiles, but the scenarios where this would be possible &/or effective are likely smaller still. But if the asteroid is a solid one, not a collection of 'rubble' or ice but an iron or solid rock, if we get enough warning & again if it's not too big then it would be possible to detonate a nuke on it or very near it to deflect it.

Their are other ideas out their (mass projector, think that's the right name lol), but as you said, their not feasible right now.

Lol, I was going to say, I was talking about DP performance (which MW@H & A@H use) not SP, but you've spotted your mistake anyway ;).

And yea let us know your 760s score.

..... seems like their should be a benchmark thread ;).

Oh yea it's silly money! ;)

If you were only looking at DP performance then you'd be better off buying a bunch of HD 6970s, or maybe 7970s.

I agree with Alex, in MW my GPU is about 51x faster than my CPU!
Also seen massive speed ups in the GPU F@H app vs CPU.

What makes A@H different?
If you did mention it in another thread (I think you may of done??) then by all means link us :).

Btw Alex, big efficiency improvement in the 750 vs 550! :)

Thanks for the GPU list, Mikey! Really helpful, not just for me, but for other readers as well!


Just be aware that with the Nvidia cards the newer the model the slower the DP crunching it can do, since Asteroids IS Double Precision you MUST be careful to understand that newer does NOT always mean faster crunchers.


Except for the Titan ;)

Wow! No wonder the table is a slow grower ;)
Btw it would be interesting to know on that table how many results their are.

Re the ~3hr WU, if you mean this 1 http://asteroidsathome.net/boinc/result.php?resultid=37859435
It looks like you added ~40 mins by it presumably running alongside another CPU intensive task. CPU time is ~2400s less than runtime.

Other than that I don't know, I can't even check out my own tasks atm as I've suspended A@H until the BOINC Pentathlon is over.

Cool! :), btw have you got a link describing those TV sticks? I've got no idea what they are, lol.

So your PC does ~57 tasks/day whilst the ARM cluster does ~55/day (no need to round up :P), which with A@H's bizarre fixed credit rate per task regardless of it's length (compared with the same h/w) makes it easy to work out credit/w. So taking the average power draw of ~173w for the PC & 130w for the ARM cluster that's 3.035w/credit for the PC & 2.363w/credit for the ARM cluster, yep it's much more efficient! Forgot to say at the start btw, cool project :).

One question though, are those TV sticks designed to run fully loaded 24/7? I doubt it, I wonder how long they'd last like that? Keep us posted! ;)

Btw your PC is pretty efficient in my books anyway, my old PC (the main rig) draws 190w running A@H on all 4 cores!

So yea your ARM cluster is more efficient, at least whilst GPU crunching isn't big in A@H anyway, I think if you did a comparison in MW@H with ARM cluster vs mid to high end AMD GPUs you might find a different picture.

(Their, I ended that going back to GPUs ;) )

Well, I do not understand much what do you mean. There is still the same number of models in Scientific Results section. We are also processing many data but results are valid because the computation was right, but the "result" of the result doesn't have to be right. Data is usually very noisy because of high magnitude so there is low success of finding the right period, but without processing all data we can't know, what part and where is data for finding the right period, if any.

Interesting, roughly what % of data do you think yields results?

I pay 14p/kWh which at todays exchange rate is €0.17/kWh, so that's nearly 42% more! :(.

Btw I'm curious, why did you pick a 42hr period? ;)
It would be interesting to see how much your PC draws, you know you can get plug in the wall power meters for not too much, mine cost £25 but that was 8 yrs ago ;).
