Mark,

If one of the criteria of this decision is that you feel left out of the GBT data as you have an exclusively NVidia farm, as I do, I'd request you add your voice to the Breakthrough Listen News thread asking that we have the option to allow it on NVidia if we choose to. I think by now we know the risks. :^)

I hope you can stick around though. As I have told myself many time, at this points: what's left to do? You could dial it back a bit and save some $ though... I wouldn't be able to stomach those power bills.

Thanks for noticing. :^) Glad it's over the $5K threshold for at least a basic setup.

To be able to run VLARs on my Nvidia GPUs I'd live with a "health warning" as suggested by Mr.Kevvy. Although I suspect some would just ignore the warning and moan like crazy.


Enstein@Home, rather than using app_info.xml to set the <count> parameter, has it in the project preferences as follows:

GPU utilization factor of BRP apps
DANGEROUS! Only touch this if you are absolutely sure of what you are doing!
Wrong setting might even damage your computer! Use solely on your own risk!
Min: -1.0 / Max: 1.0 / Default: 1.0


This seems to mitigate the moaning, so a similar caveat would certainly be sufficient here where there's less chance of overheating/hardware damage.

(My Linux machines have both CUDA and OpenCL. If they were given GUPPI VLARs, wondering how it is determined which of the two would pick them up.)

Thor flunked grade three twice...


He passed the thord time!

(You're making this too easy for me. :^D)

As a warning you should not be so flippant, remember Thor's power. As an example the poster known as ID left the project after Thor arrived.


He underestimated the power of Nathoral Thorlection!

Credits at different projects are very much like national currencies: I could make a higher number elsewhere, but as they are worth correspondingly less, it isn't worth moving there over. :^)

When I was crunching for Einstein@Home, for example, I noticed that my daily production/RAC topped out at almost exactly 4x what it peaked at here with the same farm. SETI@Home, being run by the developers of BOINC, uses a credit system based the actual FLOP count of the work unit (you can see how many operations it took in your account -> valid tasks). Some projects pay a flat rate per work unit, and of course this is open to inflation.

The VLARs go out to ATI GPUs, but are held back from NVIDIA. If I could find a way to send VLAR to only NVIDIA OpenCL and not NVIDIA CUDA, I would...


What would be a possible workaround in the interim (until someone cracks the issue of why VLAR/VHAR(?) bogs CUDA pulse detection) is a default-off setting in SETI@Home Preferences ie "Accept VLAR work units on NVidia CUDA (warning: these units may complete very slowly and cause the computer to become unresponsive)"

(Those with both dedicated crunchers and workstation computers they actually use could prevent the ones they use from slowing down by adding "home"/"school"/"work" separate preferences, putting the dedicated crunchers in one "location" setting with accepting VLAR on CUDA on, and the workstations in another "location" setting with it off.)

Here's to hoping someday someone can figure out a way to make that happen. In the meantime, looks like the need for some CPU heavy rig building.


I'll have to look at it that if the work that my NVidia GPUs do frees up CPUs and AMDs to do the work to make The Great Discovery, it's still worth it... I'll be happy if anyone makes it. :^)

I'd expect about 50/50 for the time being.


Unexpectedly large amount... excellent: doubled workload (hope the infrastructure can keep up.)

Also it was noted in NC that much of this may be VLAR due to being targeted so may be minimal(?) GPU involvement.

Guess it's time for me to invest in a CPU only cruncher, lol...


This thread may prove helpful :^)

I noticed that possibly because this campaign uses crowdfund.berkeley.edu rather than give.berkeley.edu that the donation doesn't seem to cross over to our profile... mine still shows the same number and amount of donations as before I donated, and this means that our regular "little green star" probably won't appear or be extended by it (is this correct?)

Fantastic news... thank you!

Is there any estimate on what volume of workload is going to be released in comparison to the current MB workload from Arecibo?

Here you go.

Edit: Hoping that "new GBT files" means Lunatics v0.44, which is the release that supports MB v8 which supports GBT.

Oh, Martin. Scan the QR code, infect your android phone.


Anyone using this exploit would ensure that their payload would affect as many platforms as possible.

With this move possibly more people will realize the importance of Thor and his design especially to Canada, eh?

Have donated 250, wonder how my "special" star will look like :)


That's excellent, John. I remember you were also the final donor for my fundraiser for the GBT GPUs... your generosity is amplified by the fact that your donations aren't tax-deductible as mine are (are they?)

Now that I am certain of someone picking up a "special" star I can see what it is like; I may want one too. :^)

Yes indeed a noble initiative, but there is no way to physically donate any money.


The "Claim" buttons on the right.

Well there's my annual contribution; was waiting for a need... and finally achieved a lifelong goal of being in a peer-reviewed published scientific research paper. Unfortunately I had to buy my way in, but that will have to do. ;^)

And I loved this part:

But we still suffer by association with the tin foil hat brigade, who post shaky videos of unidentified lights in the sky to YouTube, write polemics about how the government are hiding alien spacecraft at Roswell, and circulate kooky manuscripts about how ET built the pyramids.


About time!

Also any intentional signal would not be encrypted whatsoever.


Why not? Could be an intelligence test... an easy-to-find signal containing a cryptic message. Break the code and receive a copy of the Encyclopedia Galactica, membership in the Galactic Federation, etc.

We just don't know.

Unofficially, as it's third-hand, today's outrage was caused by BOINC database replica server Carolyn crashing last night, possibly due to a RAID card issue. This was from the SETI Is Down Cafe which we flock to when we can't flock to here. :^)

Before I think up a way of kludging that, would you mind doing a speed test on the Yonah, comparing both SSE2 and SSE3 with the stock app (both exist for 32-bit - I'll make up packs for you, suitable for the Main project (the ones I got for the installer were configured for Beta testing).

Edit - do you have experience of using the Lunatics 'knabench' - I can perhaps make up a barebones copy for this specific test?


Sure... would be happy to test. I've used that for testing (for raistmer) but it was scripted so I didn't need to do much but copypaste. I'll PM you with contact info so you can send files.
