1) Message boards : Number crunching : GBT ('guppi') .vlar tasks will be send to GPUs, what you think about this? (Message 1785064)

AFAIK there is no technical possibility currently to implement VLAR as "checkbox". So no opt-in or opt-out possible.


Is there any detailed reason why it wouldn't be possible?

Repost of what I wrote here:

I proposed in the Breakthrough Listen News thread that a checkbox be added to our project preferences akin to "Allow VLAR work on GPU" with an appropriate caveat ie if run on CUDA may complete slowly for less credit, cause machine slowness/lockup or work unit failure, etc.

The box would be initially off, so no one would get them and risk issue(s) unless they chose to do so. Einstein@Home has similar controls with similar caveats in their project preferences page for setting the Count parameter to allow multiple concurrent work units on GPU (which has the same risks of instability plus added bonus of hardware failure risk if the GPU overheats) and they seem to do just fine with the disclaimer, so no reason it wouldn't work here. Volunteers with mixed work and dedicated cruncher machines could set home/work/school profiles and put the machine types in them so computers they actually use wouldn't be slowed.

All I can suggest is that if you would like this to be implemented to post in that thread. If enough of us ask, it may be.


If there is a control for it, from a support and user-friendliness standpoint, it should definitely be implemented as an opt-in rather than an opt-out.

Hey - I just noticed that I have NO GBT WUs on my GPUs now. Is this because all the current GBT WUs are VLARs, or did somebody at SETI make a surreptitious change to keep them off the GPUs for RAC purposes?

Edit: Someone could also donate to Berkeley SETI Research Center to get an answer... $350 for an e-mail and $750 for a video reply. I already kicked in... sorry. :^)

Yes, it looks as though Modprobe is back in the repository with 16.04, as we know, it's Not in the Mint repository.


It just appeared for me last night (Mint 17.3); packages are cuda-drivers, nvidia-graphics-drivers-352, nvidia-modprobe and nvidia-settings in the Mint Update Manager all 352.93. I installed them on this machine and no known issues thus far. I'll probably do the rest whenever I have my next scheduled "patch Tuesday" clean day.

I used to get spammed with telemarketers. I don't anymore. I was called definitely over 50x, maybe up to 100x before I figured it out. There's a simple secret to making them stop, because threats, anger, hangups don't work:

You have to waste as much of their time as possible.

Their hit to miss rate is so bad that their margins are always close to not making money, so they have internal do-not-call lists and the only thing on them are waste-of-time numbers. They'd rather keep calling multiple quick disconnects at the same number in the hopes they will get a sucker, but a few large wastes of their time and suddenly they stop calling.

I was being called by the vacation scammers, so I would press whatever number the robocaller asked to get a person who would barely speak English, then answer their questions up to the next (and most expensive!) level of the person who could speak reasonably good English and do their spiel.

I made sure I was free ie waiting or relaxing or on transit at the time so that I could stay on the line as long as it took while they babbled, always responding positively when prompted. It took over ten minutes each time. They left the credit card part to the last, and then I would feign bad signal and hang up.

I had to do this three times, and I never got one again, and this is going on five months, whereas I was getting two or three a week for months. Hope this helps someone.

Ah thats terrible, sorry to hear that..


Thanks. :^) I'd probably be despondent if it wasn't under warranty, but I'll just Cross Ship and make do with a cruddy 570 in the interim.

This hobby certainly keeps me busy... lol.

Why not hail Thor today?
Hail Thor and his ways



Oh my... you run the risk of offending Týr on his day (Old English Tiw, Tiw's Day modernized to Tuesday.) Since his domain includes war, you don't want to get him mad.

Beater Cruncher #1 lost both a hard drive and a GTX980... good thing the card is still under warranty. Unfortunately all the cached work units were lost.

And thanks, folks, for pointing the thread in a more uplifting direction.


Hey, that's what we do and thanks for noticing. But you seem to be trying to point it back again. :^)

Please listen to what I sent clear through... it may prove helpful.

For readers of this thread who are a bit tired of melodrama, I offer unto you a small giggle today.


When I saw it, was sure it was going to be this version... was nominated for an Oscar and won a Genie for best animated short. (Probably just my Canadian biases showing... hah.) Didn't realize the song existed before the short.

Also please see this short by the same animator which won about fifty awards (no Oscar though) and is a must-see... especially for married couples. :^)

I would like to donate but unfortunately the only way I can send money abroad is via PeyPal.
Why contribution via PayPal is not possible ?


You can donate to SETI@Home via PayPal through the GPU Users Group (GPUUG). Just click the banner at the bottom of this post. (Or here is a direct link).Note that this is recognized by SETI@Home as the way to do so (read the PayPal users section).

I remember reading that Green Bank will scan the local group of galaxies, including the Maffei galaxies.


I thought the targeted search would only be the most promising Kepler objects... the furthest I know of is Kepler-40B at 8,800 ly. M31 is about 2.5Mly, so a signal from M31 would have to be at least (2.5M/8800)^2 ~ 80,700x stronger to be detected. Assuming evenly distributed signal power, we're the reciprocal of this as likely to discover something at that distance. If signal powers are more commonly what we can produce (into the megawatt range) it's even more unlikely or impossible (plus at that angular resolution isn't it going to be drowned out by the rest of the galaxy?) Hrm.

Edit: Maybe for these observations SAH is just "going along for the ride" as we do with Arecibo.

BTW, the MESSIER031 tasks are non-VLAR as far as I see and can be crunched on GPU, so no one is excluded.


Yes, getting them and very happy about that. :^) Unfortunately about 90% of them are going into -9 due to 30 or more triplets... hope it's just an initial hiccup. (These results are matching up with others', so not just my machines.)

I'm also curious what "MESSIER031" really means... Messier catalog object 31 is the Andromeda galaxy, and I doubt we are looking for ETI signals from that distance! Perhaps the area of?

I've been watching this for a week or so, and there's no way it's an illusion. I started because I was trying to figure out why mine was dropping... ie machines not getting GPU work due to GUPPI? Technical issues ie bad cruncher spitting out Invalids? One of the ways it can be seen that RAC is constantly falling is to check the Top participants. This list updates infrequently, so is a snapshot of participant RAC at that point in time. Going into each profile shows their current RAC.

Here's what we see from the top 12 at the time I posted this:

Name TP RAC Current RAC Change Lee Klopp 714,808 714,145 -663 MJS 543,177 540,824 -2,353 BojanR 455,817 454,691 -1,126 WB5TUF - Glenn 449,755 448,701 -1,054 Igor_b 426,679 426,241 -438 Fawkesguy 381,914 381,269 -645 Mr. Kevvy 375,483 374,294 -1,189 msattler 308,949 308,329 -620 DARRENS 283,672 283,181 -491 Charles Long 270,878 271,526 +648 TSTC - Cloud... 270,009 269,847 -162 toaster 260,086 259,899 -187


One increase and 11 decreases. Usually I don't even see the one increase, either. And this has been pretty much constant for over a week.

Hopefully you will see the graph which shows you what I am seeing

http://stats.free-dc.org/stats.php?page=user&proj=sah&name=71946


Don't see it there. I tried to post a graph but had the wrong one... I'll see if I can dig one one up, but yes, something has definitely changed.

Edit: The decrease can be seen here. Note the Credit per Day fall. (Ignore the Wednesdays as there is always a huge drop after the Tuesday outages.)

Well we can try to keep up


Ironic, as NVidia devices aren't getting any Breakthrough Listen data currently. Hope we are allowed to change that soon.

I don't see why someone would want to do only 1/3 or 1/4 of what he can actually do for the project.


I estimate we have from hundreds to thousands of times greater of a chance finding ETI in a GBT work unit than an Arecibo one, because it is targeted to stars that are nearby, known to have exoplanets, and known (or thought) to have them in favourable positions for life (as we know it, Jim.)

It comes down to quality over quantity. And it's rather sadly ironic that the people who have contributed to this project the most over the years in terms of work done and time/money/effort invested in doing so are now mostly excluded from its most anticipated and promising venture.
