Automatic variables are stored in the memory. As accessing a memory location takes time (much more time than accessing one of the machine's registers), one can make the computer to keep only a limited number of variables in their registers for fast processing.Whenever some variables are to be read or repeatedly used, they can be assigned as register variables.

Are automatic variables (that are defined in functions, lambdas, blocks) in C++11 thread local? Is the following code correct:

auto f1 = [
 SomeClass1 obj1;
 double z = obj1.f2(y);
 return cos(z);

// Some function which creates several threads which call f1.
