Change flag precision to flag stride, better description.
Add flag error_tolerence to define the search stopping criteria.
Move the equal condition in the binary search to smaller than condition.
Wrap get_cpu_usage(), so on non-linux platform, the compiler won't
complain and will get cpu usage to be 0.
