d195f2e8a2 intensity: do not reduce throughput before init 
Else the memory allocated could be less than required later

btw, use the new "cuda" function to apply intensity/throughput

8ad180cc70 various small changes 
heavy: reduce by 256 threads default intensity to all -i 20
cuda: put static thread init bools outside the code (made once)
api: fix nvml header to build without

1b65cd05cc heavy: add error checks, fix strict aliasing and linux 
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...

b128312efb cuda: store device SM in a global var 
sample usage made for blake and fugue (higher intensity for SM5.2)

add these to cuda_helper and clean unused code

ec709af62f Store and display average hashrate (benchmark + on share) 
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)

a747e4ca0f blake512: use a new SWAPDWORDS asm func (0.05ms) 
small improvement, do it on pentablake and heavy variants too

based on sp commit (but SWAP32 is already used for 32bit ints)

06763c20b1 Implement x14 (cuda + cpu functions) 
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
