The core problem was the cuda hefty Thread per block set to high
but took me several hours to find that...
btw... +25% in heavy 12500 with 256 threads per block... vs 128 & 512
if max reg count is set to 80...
Small echo rewrite. +10KHASH on the 650(compute 3.0)
tpruvot: add Linux Makefile - Force to 80 registers (else -30KH/s)
Note : the hashrate seems more constant with this change
nvml.dll doesnt exists for 32bit binaries! use nvapi to get infos
seems to have more/different features than NVML... like pstate etc..
This is nvapi r343 : https://developer.nvidia.com/nvapi

There was a different behavior on linux and visual studio
That was making it hard to link functions correctly
That remove some ifdef / extern "C" requirements
note about x86 releases, x86 nvml.dll is not installed on Windows x64!
Based on mwhite73 <marvin.white@gmail.com> implementation
Linked to the api system
Also fix Makefile to support standard c++ files
This prevent nvcc use without device code

Displayed data is the average of the last 50 scans in the 5 last minutes
Also move cuda common functions in a new file (cuda.cu)

stratum: handle a small cache of submitted jobs
Prevent to send duplicated shares on some pools like hashharder..
This cache keeps submitted job/nounces of the last 15 minutes
so, remove exit on repeated duplicate shares,
the submitted cache now handles this problem.

Cleaned up and adapted to my changes (cputest added)
Remove Makefile.in which should be in gitignore
(Plz refresh it with ./config.sh to compile on linux)
Project was updated for VS2013 and CUDA SDK 6.5
add also a --cputest function to dump cpu hash results
TODO: x15 is not fully functional, but first loop seems ok
