1) Message boards : Number crunching : GTX 1060 or RX 480? Best bang for Buck seti-wise? (Message 1804962)
Posted 2 days ago by Profile petri33Project Donor
Hi,

I'm sorry, but I do not make public release, not even a beta yet,

TBar can release, if he wants to, the alpha version he has tested in Linux and in MAC. MrKevvy is testing my version too and jason_gee is doing his magic.

But with a high rate of inconclusives (and low rate of errors) it is not ready. It only works with some cards (Kepler, Maxwell, Pascal), runs preferrably one at a time, needs a lot of memory, and does not get it's full potential out of the box without setting a parameter or two.

I keep on developing and experimenting with new things.

Well, the reason I am asking about these is that I am putting together One. Last. System., and it is going to be an interesting one. Similar to both my CrunchMonster and LotzaCores systems, in that like my CrunchMonster it is going to be a multi GPU setup, and like my LotzaCores system, it will be based upon a Supermicro motherboard, this time a X10DRX dual proc board. What makes this one interesting, is that it has ten 8x PCI-E slots, and the plan is to (eventually, as finances allow) utilize all 10 of them using the USB-PCI adapters. My goal is to use the 750Ti SC cards, which do not require external power, with a 1600w PSU.

The biggest thing I believe I need to worry about is properly distributing the power for those adapters, because I'm pretty sure it will be easy to overload those Molex/SATA power cables off of the PSU, considering that they were pretty much designed for floppy or DVD drives, not something sucking up 150-225+ watts...

If they don't have enough connections/cables, I will see if I can locate any 6 or 8 pin to Molex/SATA power adapters. Not sure if they are even made or not, or if they actually supply the proper voltage thru them for those USB adapters. Just thought of that off the top of my head, will def need to do more research while assembling it. Should be interesting though! :-)


The cards may not require external power, but how about the copper wires on motherboard and the connections leading to them: Can they supply?

My Linux-Knowledge is near zero.
I am happy that it is runnung. self compiling will be something to do if i have to much free time and to much money - which is still not in sight.

The CUDA60 app works fine for me, i just want it to run as only app without the other (openCL/guppi)


OK.

Wait a few weeks and You will get a better app for Your Cuda. All automagic,

You can also specify your 'exclusive app' that needs frame rate so BOINC can suspend seti work during that app.

Or you can try another linux seti app that may behave more friendly. Just PM.

The App, that needs the fps ist die GUI itself.
So i also could say boinc: only run the GPU, if nobody is using the PC. But then the PC is off. It should run while i am working with it.

So i will try to find out how to get the coproc-option working.


Hi,

Can you selbst an executable compilieren? There is a CUDA source that is schnell und has a möglichkeit to use nanoleep durch LD_PRELOAD in Linux to replace the Yield() command so there is no need for a free CPU core. (Google für instructions: setiathome nanosleep) http://setiathome.berkeley.edu/forum_thread.php?id=74160&postid=1480595

The source code is in die SVN. (The up-leftmost toolbar 'HOME' - 'porting & optimization' - 'branches' - 'sah_v7_opt' - 'Xbranch' - 'client' - 'alpha' - 'PetriR_raw3'

Download and install cuda dev toolkit 6.5, 7.5 and 8.0 from NVIDIA. Yes. You need all of them. I use 8.0 compiler (NVCC), 7.5 include files and 6.5 libraries (cudart and cufft).

export PATH=/usr/local/cuda-8.0/bin/:$PATH
and
make

Test offline. I use KWSN MB benchmark from Lunatics for offline testing.

Then deploy.

(Or just wait a few weeks-months more for a pre-compiled version to show up.)[url][/url][url][/url]

Posted 11 days ago by Profile petri33Project Donor
On my Ubuntu-PC with a GTX750ti i want to not allow guppis and OpenCL to be downloaded.
These WUs lead to an framerate of about 0.5fps. The PC cannot be used any more.
Normal CUDA-WUs work fine, so i only want to get theses WUs. In Windows i only got them, maybe because of the 2 years old grafic driver.
Aborting the unwanted WUs makes a lot of work and is not the best way.

So i tried a app-info.xml:
<app_info> <app> <name>setiathome_v8</name> </app> <file_info> <name>setiathome_8.01_x86_64-pc-linux-gnu__cuda60</name> <executable/> </file_info> <app_version> <app_name>setiathome_v8</app_name> <version_num>801</version_num> <file_ref> <file_name>setiathome_8.01_x86_64-pc-linux-gnu__cuda60</file_name> <main_program/> </file_ref> </app_version> </app_info>


At first it seems to work, but after restart, all apps were deleted and all WUs were aborted (but not reported as aborted by the boinc-manager, so they are in the nirvana now)

What is wrong in the app-info.xml? (i only want the normal CUDA60-WUs)

Is it possible at the project side to get openCL-normal, openCL-guppi, CUDA-normal and CUDA-guppi as separated sub-projects (like astropulse) instead of all together put in "seti v8"?

Where (with a red X) would a random computer (with an experimental software) be?

I assume you're talking about your monster?

It looks like average of 1873cr/hr per GPU -- looking at your RAC that's about right. I'm not really sure you're your managing to do it but you're somehow out-performing the average by nearly a factor of 2.


As a programmer I'm used to make the most out of any given hardware.

a) The guppi wu's do not have more work in them, they just happen to have low ar that makes the current software not to parallelize the pulse find calculations. I've fixed that.
b) Cuda streams can be used to utilize the GPU more efficiently
c) Memory access pattern and cache utilization can be improved
d) Instruction level parallelism can be increased
e) The autocorrelation can use the nvidia R2C fft implementation more efficiently than the current C2C fft.
e) As the performance grows so does the heat production too. My cpu's are running at high 60's C even with a HVAC duct blower aimed directly at them.

146 points in under 4-6 minutes. I wouldn't swap. Just wait -- it is coming to you all NV people.

Soon?
Please say "very soon."


Will 'pretty soon' do ? Probably will be spending today trying to find out if my Father's still in Turkey or not, but other than that plan was to escalate Several builds to wider testing, while some boincapi and older gen issues get ironed out.



I think 'pretty soon' would be enough. -- too late some would say :)

The results weren't too crazy:




First of all, Shaggie, really nice work we have here !! Big service to the community, as deciding what to use to crunch is easyer now!!

But you scared me : my system has 3x GTX660ti, 1x GTX780ti and 1x GTX1080, so, by visually extrapolating my data from your graph :

- Worst scenario : 2700 WU/h
- Best scenario : 3010 WU/h

And my average credit per day now is about 1950, and with medium OC !!!

Dunno what to say...

Care to run a report on last 5 crunching days of my system, or is it too much work ? http://setiathome.berkeley.edu/results.php?hostid=8035198

Anyway, thank you !!

A.


Nice graphs! Thank You!

I copied a piece of a code so that Cuda special edition obeys the same convention. For debugging convenience.

Petri R.

Oh, very good! At last we will be able to investigate validation issues directly, w/o re-running offline first.
Also, look into -v 2 functionality. It prints best signals as they develops. I found it quite useful too while in validation-check more.


I'll do that next as soon as I have time.

I am using a couple of these with success, but some motherboards simply refuse to see them on the PCIE buss.
A mobo bios update might help, or might not.


Any of Your kitties coming to Europe? I'd strap back a GTX780 and some kibble with instructions to the airlines to keep good care of.

I'm afraid my two remaining kitties are much too old to be gallivanting about anymore.
But, thanks for the offer.

Meow - see my EDIT.

I had a friendship with a cat - that friendship lasted for 17 years. MeoW!

-- for the memory of my password recovery question. --

Well, mine are both just a couple of months away from 15yo....so, no traveling for them....LOL.


So, yeah

No travelling for them.

I'll have to wait some more agile kitties to come, hopefully with their families and ready to tell their stories and stay with us a little longer.

Calm down. Guppi is a piece of cake. See my times.

All I see is your RAC and your rig with 4 GTX 1080!!!
I would laugh at guppis too with that rig ;-}
...but I'll settle for your new apps. What's the ETA?
Cheers,

Hi Rob,

If you'd look at my results you'd see that I have but only a single one 1080. :)

There are some errors to iron out, but with the help of my friends and the long summer vacation and the ultimate understanding of my spouse and my family You all will be eventually enjoying the fruits of my lonely nights at the keyboard etc.

That's what I hope. And I know there are a couple of Heavy Duty professionals ... So I'll get a good night sleep.

I'm awaiting as much as all of the rest of you with NV HW. We know where the slowness comes from. I know what to do with it. But I have a life. *


* Committed to crunching.
19) Message boards : Number crunching : What is "an exclusive app?" (Message 1801418)
Posted 20 days ago by Profile petri33Project Donor
A whole bunch of tasks had the following heading: GPU suspended - an exclusive app is running

What does that mean?

Only two S@H tasks were running, none of the other projects.

S.Gaber


An exclusive app is an application that You want to run as if there were no scientific applications running at all in the background.

I.e. if your game or a video or whatever application is experiencing any king of lag or stutter or having any kind of anomaly you can say it is an exclusive app and the Boinc system will give it a way to run without any Boinc app disturbing its execution. Kind of keeping the user experience at th highest definition level of any (and not including some of the major commercial) standards.

That is one of the mechanisms to keep peoples computers responsive and still productive.

Hi there,

I tried two different USB riser cards with molex power connectors with a bad luck - couldn't get them working.

If any of You or your relatives or friends are traveling north Europe I could gift the three first ones with a (one per traveler or a group) very well used GTX780 for free. The two first get an USB riser as a bonus.

Me.
