REVERT: temporarily disabled fastest CUDA detection, since it strangely causes error on dvl machine (reverted from commit 1459580e)

adding older preliminary data for the initial Autotuning algorithm. Results obtained on dvl01 machine

WATCH OUT! This is additional CUDA timing profiling activated by setting BIOEM_DEBUG_OUTPUT=4. However, this profiling is quite intrusive, as it adds additional synchronizations between GPUs and OMP that are now sequentially working on maps comparison. If the BIOEM_DEBUG_OUTPUT<4, code is ignored and the performance is back to normal
