Very good result. AMD has an even bigger lead in 32B. My GTX 980@stock had to crunch for nearly 51 minutes.
-
I've just added "GPUPI - 32B" and "GPUPI for CPU - 1B" to the benchmarks. Let's hope you use it.
Btw, I guess there should be a discussion if it's allowed to use CUDA for NVIDIA cards to compete in the rankings. Well, that's why I have so carefully implemented CUDA and OpenCL so close together. I think it would be fair, because any performance improvement is due to the vendor's implementation and optimization of kernel, which is basicly the same.

Guys, version 1.3 is here. The whole code was refactored and allows multiple APIs now, that are loaded when the system supports it. The new version also includes a standalone for OpenCL and CUDA. The main reason is that the OpenCL version will run on Windows XP, the CUDA version won't.
The CUDA implementation was pretty easy and also uses less code to work. Especially the part to setup the application and prepare the calculation was a piece of cake compared to OpenCL. That said, I tried to be as fair as possible and implemented both APIs with each of their advantages, but still rely on the same algorithms and the same basic optimizations. I've also adjusted the OpenCL code a little bit to get them closer together, so the new version might differ a few milliseconds from the results of 1.2. Please use the new version as of now.
As requested I added two more digits to reach: 20B and 32B. Smaller graphics cards and CPUs will have to crunch those for days. Karl would have loved it!
Have a fun and let me know your results and what you think!

I'm currently testing the CUDA implementation with 32B digits. Takes about 50 minutes on a GTX 980 with stock clocks. Long enough?
I will release version 1.3 later today.
-
10B already takes about 15 minutes on my GTX 980. 20B would be possible without adapting the algorithm for higher precision. But I have to test.If you don't mind... please do a 2nd setting which takes a bit longer. What about 32B? Sure, most people prefer short benchmarks, but something heavy is also worth considering.I am currently working on a CUDA implementation. Just curious to see how good the OpenCL implementation of NVIDIA really is.
-
Did you install the newest drivers? Are you sure they can handle OpenCL? If the device doesn't support double precision but can be detected on the system, it will get listed as ignored when starting the benchmark. I'm not sure about your cards, GTS 250 seems to have double support, I think.i know its beta.my gts 250 and Radeon HD 7650M not detected
Detection is mostly a driver issue and has not much to with the benchmark itself.

Under 20 seconds with R9 290X.

No. It's pure OpenCL with C++. I used no libraries/APIs except pure WIN32, STL and of course OpenCL via the Intel SDK.
-
It should be easy. These DLLs are needed for every C++ application that's done in Visual Studio 2013. Just be sure to install the vcredist_x86.exe and run GPUPI.exe, the 32 bit version of the bench. Ignore the 64 bit version, even if you're on a 64 bit OS. It's not faster in any way.I read faq and had to download software but when I did it was already installed so stopped install. Get same error messagr missing xxxxx -
Dinos, have you read the FAQ? What's the problem? Which graphics card are you using?
No, it's not 1M, it's 1B. 1 BILLION!
1M is like 0.01 seconds or so.
-
I've seen no difference at all. High GPU core frequency is what counts, and of course choosing the best graphics card for the task.I barely even know what it means but was suprised when I saw HD4850 supported... HD5770 - NOPE.How do you think performance between quadro and geforce are? If it's anything like oclhashcat then there's virtually no difference...?
It seems like the R9 290 is the best choice so far, because it has a very good integer performance.
-
I renamed the bench to "GPUPI - 1B". And thanks!
The first submissions are rolling in ... yeah!

I've just found out that I can release the benchmark in a beta version myself. It's now listed in the Videocard benchmark list.
-
Yes. Target platform for compilation was Windows XP upwards. Please try it out, I didn't test it myself yet. But I wouldn't know of any advantage in doing that. Currently it seems like the newest drivers get the best results.Does it also work in XP? -
Thanks!
I've already written Pieter on Facebook, but he seemed busy. He said that he will have a look tomorrow or so. The benchmark is already submitted to the HWBot application thingie.

In the last few weeks I've been working on a benchmark to calculate pi on graphics cards. It's an idea that's in my head for some years now, but I couldn't put it to life until now. Somehow the death of our beloved Turrican inspired me - I wanted to do something good, something that matters. So I tried hard and it finally worked out. I want to dedicate this benchmark to Turrican, like a virtual monument to never forget his legend. A benchmark in his honour.
Together with the community of overclockers.at I've tested the benchmark for the last week and put out some new versions, wrote a technical description and added some frequently asked questions. It's still a beta version, but it should be pretty stable with most of the graphics cards and processors around. But be sure to install the latest GPU/OpenCL drivers for the target device, old ones can be very bugged.
Here are a few examples for calculating the billionth digit of pi:
GPUPI 1B: AMD Radeon R9 290, NVIDIA GeForce GTX 980 and Intel Core i7-4960X@4 GHz
I think that there's a lot of potential in a benchmark like this, it's just fun to crunch pi on a gpu. If you like it, I would consider implementing multi gpu support and hwbot direct submission. Bugs and feature suggestions can be made here or in the international support thread at our forums.

Great score. Congrats!

Before any doubts of hardware sharing come up, we've binned 11 modules of Hynix MFR from ADATA and Corsair. Our best module died from high voltage but 2nd and 3rd stick could do 1930 mhz (splmann's result) and 1901 mhz (my result).
Pictures and a back story (in German) can be found on our site: http://www.overclockers.at/articles/the-show-must-go-on/page_3

It's a relative link (/submission/...), but it should be an absolute one (http://hwbot.org/submission). Just click the link, go to the address bar an remove the "forum." part.odd that all score links are broken when you try to view the score via forum -
We have binned a 3770K that easily does 6 GHz benchstable and maybe a bit more with 1.4 volts under cold. But guess what ... it does not scale with voltage, so 6.2 GHz is about the maximum the cpu can do with 4 cores. And that was one piece out of 55 cpus we tested.
-
We used the ASUS Engineering BIOS, so the voltage was locked at 1,21 volts. We had no throttling and slowdowns after that. Our Titan was also pretty easy to work with, no shutdowns until -140 °C (measured on the pot but near gpu). But cold did not help that much, without vmods the card is limited as hell. But I guess it could get some pretty decent scores, if it's modded.Ok, on our first titan, we try to put LN2 without mod. With cold, boost stay @max, but Vgpu start @1.17v and drop at 1.02v few seconde after
.I have to made "GPU shutdows and slowdown" mod to keep full Vgpu under cold. Titan is realy powerfull, but it need a lot of Vmod.
On your card, no throttle or Vgpu drop under cold ?
Congrats to everybody who made the cut. Have a nice time in Moscow, you earned it!
-
We poured ln2 on the card, but that was already risky. No volt mods allowed though, so we couldn't do too much damage either way.@Mat : Strategos San and I have made some score under LN2 with stock VRM...but be careful, VRM are very cheap. Be sure you can remove every thing properly in case of RMA... 2 Titan already gone...
-
Everyone is doing zombie mods now? Overclocking has certainly evolved!
oanvoanc and me just started with our first results. We have a good cpu, but only a borrowed Titan - and we're not allowed to hurt it (whatever that means!
). Well, we're doing our best anyways, because that's what it's all about, right? Here are some pictures from our first days:
We are trying to get the Austrians involved in our progress, so you can find more pictures in our (german) article: http://www.overclockers.at/articles/asus-open-overclocking-cup-2013-wir-sind-dabei

That's the way it is. And doing it live in front of an audience doesn't help either! So congratulations on your huge score, Mike!thanks guys. Moose, i've been having issues with TW on this board for a few days now. When i did the amd stuff, i tried this setup and only managed 63k, TW was all over the place. When I did this install at home, i got around 48k TW on air at 5ghz. Thats whats been hurting my score the most. You know this bench is a balance of getting everything to work right, and it was enough for a score, but not everything was working right.
