Testing parallel mode/extension of g++.
See Parallel Mode of GCC for more details.
See the task.cpp for details - basically it generates some large vector of random numbers and sorts them few times using standrd std::sort and parallel version of it.
Just run make.
Then running ./task produces following results on my machine:
./task
Generating 10000000 numbers...done (1329.56)
