Minor cleanups and CMake Min. Versions

[ax3l]

• CMake: check for boost 1.49+ (move) and CUDA 5.0+ (hypnos fallback)
• includes: add missing mpl/find header
• virtual inheritance: remove : virtual public BaseClass (not really necessary but complicates GPUOcelot parses)
• kernels: remove only static kernel function in the whole code (not necessary)

Dare you compile suite, why does no one update your cuda? :)

[f-schmitt]

What's the dependency that forces this?

[ax3l]

Actually, we require CUDA 5.5 due to driver bugs at least with the sm_35 architecture. But one can use cuda 5.0 with cuda-5.5-like drivers.

@psychocoderHPC Knows why we need CUDA 5.0+ itself. I have in mind some minor features/bugs required updating (at least today, I recognised compile errors with cuda 4.2 + recent boost versions).

[f-schmitt]

CUDA 5.5 drivers are currently unavailable on Taurus due to ECC problems.

[ax3l]

I know, that complicates the whole dependency problem cycle, but forcing 5.0+ should be flexible enough for that.

[psychocoderHPC]

CUDA 5.0 is now one year old. I think it is OK to say that we support 5.0+ (we had no system with 4.2 to check bugs).

[ax3l]

👍 One also has to keep in mind, that installing CUDA only gets easier with new versions and new CUDA versions usually run on old hardware without problems.

[f-schmitt]

Agreed. I see no particular problem in enforcing CUDA 5.0. Once we start to grow our user base, we might think about staying backward compatible, since many users won't be able to alter the installations on their clusters.

[ax3l]

I am updating the CompileSuite client to run with boost 1.49 (already) and Cuda 5.5. Afterwards I will push an other commit (find libSplash version number in CMake) to trigger a new test.

[f-schmitt]

I'll have a last look and merge that tomorrow.

[f-schmitt]

Looks good to me, it goes in.
