If you change the action to Print[DownValues[DuplicateNotebook]], it strangely prints {}.

comment Trial version 10 vs Version 10 Prerelease 13
I tried to write a general answer that will be useful to more people with similar problems. I hope it will solve the problem you see as well.

Close Mathematica, then hold down Shift-Control while starting it again. Did it fix the problem? (Reference)

comment OpenCL vs. CUDA with Mathematica
This is a useful read. In Mathematica, CUDALink has more useful functions that OpenCLLink. Both the CUDALink and the OpenCLLink demos work fine for me on a 2012 MacBook Pro, but I didn't go deep into the technologies. I think using them from Mathematica will be quite similar.

comment Does Dataset round?
Yes, that's a very useful observation, you already got my +1 for it. I meant that I'd say it's a formatting/display bug.

If you agree that it's a bug, go ahead and add the tag.

comment Does Dataset round?
That's pretty misleading though, I'd still call it a bug. It is possible that it simply rounds to 4 digits, regardless of how many digits are to the left of the decimal point and how many to the right. It might make sense to round 2.34567 * 10^6 to 2.346 * 10^6, but it makes no sense to round 2345670 to 2346000 for display purposes.

comment Mathematica cannot find the c compiler
Then the compiler is likely not properly installed. There should be an environment variable names VS90COMNTOOLS or similar. Can you check if it exists? Evaluate GetEnvironment[] and look for it.

comment Mathematica cannot find the c compiler
Do not set $CCompiler. If the Microsoft compiler is installed correctly, Mathematica will auto-detect it. Re-start Mathematica (including the front end) after installing the compiler.
