I'm looking for a pure GPU number, surely 20-25k includes the CPU, right? If not that would be an amazing RAC :)

Thanks!

I'm thinking of buying a RX480 GPU for the sole purpose of raising my RAC. Do you know what RAC can be expected from such a card? Bonus question, would 8GB of VRAM make difference as opposed to the 4GB versions?

Thanks!

Is AMD better for crunching SETI? Obviously it is all in the details, hence the similarly priced latest generation GPUs in the thread's title, but I seem to recall seeing something on the subject of AMD being better in general. Something about its architecture being better suited for the SETI tasks...

Any thoughts?

Hi Songbird,

. . May I ask what you are running?? Stock? Lunatics? And CUDA or S0G? There are tweaks to release the CPU from the monopolistic grip of SoG if you want to.

. . For the GTX970 if you are running SoG, in the command line file in your BOINC data directory "Projects/Seti@Home" called "mb_cmdline_win_x86_SSE3_OpenCL_NV.txt" (there may be _S0G after the NV if you are running r3500) [you can edit it with a text editor like Notepad] add "-high_prec_timer -use_sleep" you will then find your CPUs are no longer wholly monopolised.

I'm running lunatics 0.45 beta for SoG.(MB8_win_x86_SSE3_OpenCL_NV_SoG_r3500.exe). I did the command line thing. CPU dropped significantly. It's better but still nothing like the CUDA apps from before.

Thanks!

I have a question. Is there an ETA on when this silliness with the 100% CPU usage (when crunching on GPU) is going to end? I have a GTX 970 specially bought to crunch, instead of the CPU and now my brain hurts every time I see the full CPU core when crunching on GPU.

Hi,

May I ask what does "Signal on GPU" mean? We've been testing signals on GPUs for years, haven't we? What changed?

Regards,
Georgi

It's in the New York Times. I'm putting the answer to my question as a definite maybe!

11) Message boards : Number crunching : New app? (Message 1756372)

Couldn't post it to the beta forums so let me use this one.

I just started crunching with the cuda50 app on beta, do i need to do anything else regarding the testing (taking notes, reporting stuff) or you get your info from some BOINC logging facilities? If I want to be useful that is...

And here is Richards release post for CUDA on Beta:
https://setiweb.ssl.berkeley.edu/beta/forum_thread.php?id=2266&postid=55789#55789

Notice that he says:

"First availability of Windows SETI MB v8 CUDA applications for NVidia cards.

These are for use on the BETA SITE ONLY".
--------------------------------------------------------------------------
But then of course, should one want to do it anyhow, hiding ones computers would be the first step....

Hmm, Science of RAC, Science or RAC....:-)
Nuff said about that....

I hadn't seen that. I don't really have a problem not using the cuda app on main - I just was not aware of the constraints...

I tried using the OpenCL app for NV but it was just not working for me. I'll just wait for it to go to main.

It is highly recommended that Beta apps stay on beta.

I think RIchard posted something about consequences if you are caught.

So best to leave testing apps on the testing site.

I think it was about V7 app being used for V8 workunits. I've already used beta apps openly (the OpenCL one) and nobody said I should not.

Yeah, I'm at least 50k RAC down since V8 was introduced. About 17k because of a GPU only cruncher and a bunch other machines that have lunatics installed on them.

I tried the MB8_win_x86_SSE3_OpenCL_NV_r3310 app on my GTX970 but it seems to hog a CPU core as well. Any info on that?

Is there going to be a Cuda app in the near future?

This is a question that only a handful of SETI staff can actually answer but nonetheless let me post it here...

Have the Chinese been approached for installation of a piggyback device, similar to the one installed on Arecibo, for the FAST radio telescope currently under construction?

I recently plugged in this computer. It produces in my opinion an abnormal amount of invalids. Could this be diagnosed?

I'm using the optimized apps from Lunatics 0.43b installer.
