Default GPUPI - SuperPI on the GPU



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.

A graphics bench that is actually only using the GPU, about time really

That's awesome! Maybe we can add it as Beta benchmark.

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.

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.

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.

Please rename the benchmark to GPUPI 1Billion or whatever default setting you expect us to run.
And good job on this!
