Is it CUDA 4.2 related problem? Or is it general? I have problem with my cuda app, which stuck when syncing with cpu on linux.

Thanks
Zdenek

Why wouldn't (possibly) the fix for the titan not fix the 780?

Edit: HA: its gotta be a problem with CUDA 4.5, because mine crunches fine on Einstein and is returning valid results. It does encounter a hiccup on occassion though, maybe once a week.

I have problems with my titan on linux with cuda 5.0 also. No problem with 5xx and 6xx cards. I try to figure out where is problem? driver, card or an app. (or motherboard and pci maybe)

back to the gtx-670...

Nvidia has now recognized the problem and it is working on a fix for Titans which should be out in a month or so. It could be a new driver or a bios update.

It's not the fact there's no fix that bothers me. It's that they didn't say anything about thia topic the entire time. In the meanwhile, people, including myself are purchasing parts. Because why not, we haven't been told there was any serious issues.

We were told the dev was away. Serious breakdown in communication, and is making me think about switching projects.

Cheers.

Hmm i dont know.i dont want to sound rude...but buying hardware thats not supported is not the fault from the projectadmin i would presume O.o

But i would think more positive now and hope that the update will work for both titans and 780.

That I understand. What I don't like was the complete lack of communication in regards to the topic. If they knew it wasn't functioning, was able to contact NVIDIA, and get a response. That's a lot of time we were all left in the dark. Not a word was spoken.

Thank you for responding. What I'm attempting to get at is simply WUs failing does not bother me. That isn't a sign the cards could *never* work.

I haven't lost an investment either :) Ive been wanting to build a new rig for awhile, since the next one won't be to Maxwell comes out, and I can hopefully pair them with an 8 core has well-e

I'm looking forward to hearing back from you guys in regards to what NVIDIA does. Just remember, all we saw was very few actually completed, most failed. But some did complete. There was no reason for us to expect this updated thread today.

Again, I enjoy crunching here. I just wish there was more communication at times.

Just to point out, these are the relevant dev responses, and why I'm bringing this up:

1) Update on Titan app:
First of all, Titans should only work on the Beta queue right now. Once we are sure it works we will extend it to the other queues. But we need to do some final testing which I think I am going to organize later today, since there is noone else actively working on it.

What we have: Supposedly the app works fine for Linux and Titans
What we lack: Even a single occurrence where a Windows Titan crunched a Beta app successfully.

So, later today I am going to tell someone in the lab to send some stable simulations to the Beta queue and if there are any successes from Titan users especially from Windows (Linux users can report too) we would have some very helpful results.

Also, MJH tells me that if you are using Titans and the WU's run for a while and then always crash before completion, then you might need to downgrade to driver 310.44 or later in the 310 series as it is supposed to help a bit in our experience.

I will keep you updated.

2) Hm didn't know that. Then maybe MJH meant that it worked locally on our Linux Titans? Sorry for the confusion. Well in any case, it's Windows we want to test right now.

3) @Zarck Yes I was watching your machine. Actually right now all the beta WUs seem to fail which would rather point to a general problem in the new app and not just the Titans. Once this batch is done I will pass on the information.

Thanks for the testing and info though!

4) Unfortunately our developer for the TITANs (and their kind) comes back in July so we will have to wait a bit more. But it is quite high on our priorities to fix the problem with the new GPU's considering that eventually everyone will switch to the new generation (and they provide great performance boost).
-------

No where here does it even hint that there is a problem near the magnitude as currently described to us. All that's really said is, Linux seems to work on ours, it appears to be a problem with our app (fixable on your end), and we need to do some final testing (final testing tends to be good).

This is all I'm getting at. There was nothing about, "At the moment Titans and GTX780s do NOT work. After a short time the application crashes". Meaning, NOTHING is working correctly, this could take some time. Best hold off on getting these parts, because we don't know what's going on or why :)

Hope my point finally get's across. Again, best of luck with NVIDIA. Hope they clear everything up in a short time frame.

GDF: Out of curiosity is it technically possible to break the WU into smaller units? Thanks

I do not know where the problem is.

I have a Titan is a number of Boinc projects run smoothly with my Titan and any version of Boinc and nVidia driver, for example,
Moo!, DistrRTgen, PrimGrid, WCG HCC, Einstein, Seti.
Is it really a problem of nVidia driver and Boinc?

GPUGRID use functions that other projects do not use? so that GPUGRID does not work with my Titan?

Folding @ Home also runs smoothly.

I calculated what units BitCoin GPU in Utopia, it makes many units without problem, and occasionally I have a blue screen, and windows restarts.
The manager of BitCoin Utopia project asked me to send him the "Windows event log", you need this file?

Je ne sais pas ou est le problème.

J'ai une Titan est un certain nombre de projets Boinc tournent sans problème avec ma Titan et n'importe quelle version de Boinc et du pilote nVidia, comme par exemple,
Moo!, DistrRTgen, PrimGrid, WCG HCC, Einstein, Seti.
Est ce vraiment un problème du pilote nVidia et de Boinc ?

GpuGrid utillise des fonctions que d'autres projets n'utilise pas ? ce qui fait que GpuGrid ne fonctionne pas avec ma Titan ?

Folding@Home tourne aussi sans problème.

J'ai calculé quelles unités GPU sous BitCoin Utopia, il enchaine de nombreuses unités sans problème, et de temps en temps, j'ai un écran bleu, et windows redémarre.
Le gestionnaire du projet BitCoin Utopia; ma demandé de lui envoyé le "Windows event log", avez-vous besoin de ce fichier ?

Folding@home WUs did work, but were fairly slow. Their new beta tasks however were blazing fast.

Again, I am curious as to why the fix wouldn't be for both, I know you don't know the answer, nor understand yourself, just curious is all. :)

Best of luck to Titan owners in the coming weeks. Their recent drivers have been buggy as hell with these gpus, so I'm actually wondering why these are so different compared to other cards, since its the same architecture.

Folding is now optimized for GeForce Titan, and performance are now multiplied by 2. Future nVidia driver will support the compilation just in time "JIT" and still allow new significant performance gains.

http://folding.typepad.com/news/2013/06/welcome-to-fahcore-17.html

"Welcome to FahCore 17!

We are proud to announce that our latest GPU core, FahCore 17, was recently moved from beta to advanced testing, the last quality assurance step before a full release. As we previously mentioned, this core is a significant step for us. FahCore 17 is a complete overhaul from our previous GPU cores. It brings a cleaner and more streamlined codebase, new serialization mechanisms that allow us to set up diverse simulations, and improved stability. Its use of OpenCL has united our development, allowing the single core to run on both Nvidia and AMD cards, and theoretically any OpenCL-capable device. It is also our first GPU core to run natively in Linux, although we are only supporting Nvidia GPUs there for the time being as we wait for AMD's Linux drivers to mature a bit more. Overall, this core sets a strong foundation for the future of GPU core development.
On AMD cards, FahCore 17 is about 10 times faster than the old GPU cores, and on Nvidia it's about twice as fast. This is mainly due to its OpenMM 5.1 base, which contains many optimizations which deliver a significant speedup. One optimization in particular that we are waiting for is CUDA JIT, a just-in-time compiler that Nvidia may be introducing into its drivers in the coming future. Not only will this technology allow us to offer support for the CUDA platform with FahCore 17, but the JIT compiler is likely to deliver a massive speedup. For the time being, we continue to work at finding additional optimizations on our end. We have also successfully tested FahCore 17 with extremely large proteins (500,000+ atoms), which are on par with the ones used by "bigadv" CPU projects.

To run FahCore 17, you need a Fermi GPU or better and Windows or Linux, or a AMD HD5000 or better and Windows. It also currently requires proprietary drivers from these vendors. You can test FahCore 17 by adding the "client-type = advanced" setting into the extra core options in the V7 client, as in the Configuration FAQ. Another excellent resource is the GPU FAQ which describes why GPUs are so helpful to us.

We'd like to thank all the alpha testers on FreeNode's #fah IRC channel, as well as the beta testers on foldingforum.org, who have all helped us bring the core to this point!"

You mention Titans working at Primegrid...it's true that they work, but not at all as expected. I've done some PG testing of my own with my Titan on GFN and some PSA apps, which require FP64, something the Titan is supposed to excel at. It does not. Turning the FP64 ability on and of in the Control Panel adds 4-5% speed increase at best, when it should be closer to 650% (taking into account the clock speed reduction when enabling FP64). So although it "works", it does not work properly.

I also did some testing at Albert@home. Again, the Titan "works", but not properly. WUs take 2x longer to complete on the Titan than on a GTX 560. I haven't tested if the results are the same for Einstein, but you might assume they are.

There is something seriously wrong somewhere, and hopefully Nvidia finally gets it right sooner rather than later, especially since i spent the extra cash and got the EVGA Hydro Copper version. It never runs above 39C at full load, so temps have nothing to do with these issues.

Edit: Also i've had no luck at Poem either. Instant crashes everytime, same as with GPUgrid.

Einstein does not use FP64. So, that is a non issue there. The gk110s do work there, and that is where mine are currently at. However, due to a bug that it would appear NVIDIA is unwilling to fix, they cannot move forward optimizing their CUDA app. AMD excels there on their latest tasks because of it. It's not that they don't perform well, they do, just not as well.

Einstein is running new WUs, and for whatever reason, I'm having scaling issues on my 780. They don't scale at a 50% increase in time anymore. In fact, mine were pretty much double.

Again, I can only assume this has something to do with the new WUs, and the bug NVIDIA seems unwilling to fix for them. They're stuck on CUDA 3 or something like that.

If you are going to use a Titan at Einstein I think it's best to run several WU's consecutively. IIRC running 7 Einstein WU's takes as long as running 1, but you get 7 times the credits. It's probably the same situation at Albert too.

This seems to be finally fixed in the current release candidate of CUDA 5.5. We'll see how it comes out when they actually release it.

This driver works for titan and gtx780 in the sense that simulation is now stable.

We will be getting out a new application asap.

Well thats one down. Fingers crosser windows is released and stable.

This is the one:

My guess is yes, thats the one. But if youre asking for einstein, they're their own app, but I do hope these fix their issue as well.

release the betas!!

You misunderstand. Einstein is running on CUDA 3, thx to a bug that apparently may be fixed in 5.5. It runs, but is very poorly optimized for 600+ nvidia gpus

Splash away my friend. I've bought 2 780s. Same deal happened to me when the 680s were released. Had to wait several+ weeks in order to get GPUgrid to get their app functioning. Used them over at Einstein@home in the meantime.

Always takes awhile. Sometimes longer than others. I'm expecting Maxwell to take them awhile to release a functioning app when those GPUs come out as well. The anticipated jump in computing performance is so large that I just can't fathom everything working smoothly.

Play some games, d/l 3d mark and try to get a high score. Enjoy your hardware til the devs get their end straightened out. Personally, I've been debating on purchasing crysis 3 and running it at 1440p just to see how far I can push everything.

It's fun.

I've only seen Zarcks Titan complete a beta. Well three actually but only a 2.6% success rate. Using 326.41 driver, Windows8, Boinc 7.2.1

I get off work in 4 hours. I can download the new driver and attach my 780s then. Dont know if the fix is only for titans though.

hi,
can you attach the titan to the beta application?

gdf

6.49 is old beta app. I think.

All WUs are crashing instantly.

Not sure if I have show others enabled (or how to) but here ya go http://www.gpugrid.net/result.php?resultid=7138686

I have opted out of betas in my preferences but I'm still getting them. What's up with that?

For my Titan, back to BitCoin utopia, and Rosetta for my Cpu.

"Lots of changes
I made three new projects:
Project #1: Donating $1000 for Mars One
Project #2: Donating $1000 for SETI@home
Project #3: Donating $399 for Hydroponics Research Stage 1

I also changed the bitcoin pool. The old was 50BTC. The new is BitMinter. It also generates some namecoins when mining bitcoins for BitMinter. I also tested p2pool.org (the one I used for mining a good amount of terracoins), but I cancelled most of those workunits yesterday. Not only namecoins, but Bitminter also allows to use Java application to mine for Bitminter pool. I'll add that to the project website soon.

Operator: At this point only the Beta queue is supposed to work for Titans. So we are testing them there. If we see that they work in the Beta we will put it to the other queues too. So it's pretty clear that it would crash on the short (or is Santi long?)

Will try it again with 'beta only' preferences to see what happens.

Operator.

Just FYI.

I've had weird sporadic crashes with Titan on all CUDA applications so haven't been able to try any science applications properly, mainly Primegrid Genefer & Genefer WR though. Crashes happened even when downclocking the Titan all the way down and even now on totally new platform (Haswell).

Been following different projects which would have Titan support, but it seems it really was the driver which have been faulty.

The new Nvidia Beta driver 326.41 seems to have fixed this, at least my Primegrid Genefer runs have been all successful with no crashes on Cuda and OpenCL after updating to that driver version.

Before that using any driver and downclocking the GPU did not help. Now it runs happily with double precision enabled on default clocks of the card, with driver 326.41. No crashes and no errors.

I might be able to test GPUGrid beta run later on to see if it works for your application also. Will try to set up everything later on the evening.

Hello!,
