Syntax
ok = multi_atomic_run(y_squared, square_root)

It is assumed that this function is called by thread zero and all the other threads are blocked (waiting).

y_squared
This argument has prototype       const vector<double>& y_squared  and its size is equal to the number of threads. It is the values that we are computing the square root of.

square_root
This argument has prototype       vector<double>& square_root  The input value of square_root does not matter. Upon return, it has the same size and is the element by element square root of y_squared .

ok
This return value has prototype       bool ok  If it is false, multi_atomic_run detected an error.
