No. It's pure OpenCL with C++. I used no libraries/APIs except pure WIN32, STL and of course OpenCL via the Intel SDK.

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.

Detection is mostly a driver issue and has not much to with the benchmark itself.

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.

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.

I am currently working on a CUDA implementation. Just curious to see how good the OpenCL implementation of NVIDIA really is.

What about 16B, then? 20 would be cool. It would be somewhat interesting in a few years - even wprime 1024m is not what it used to be because it's almost over before it really began

+1 for really large problem instances. Computing power in GPUs grows a lot faster than "+5%" per year so if a test takes 20s now, in a couple of years it will be faster than 1M.
