How to make parallel execution of several functions?

Question

C++ / C#

There is a vector vector, you need to sort it in parallel and bring it to lower case.
I don't even know what to do :(

Answer 1

C++11: std::async, std::thread,
VS (Parallel Patterns Library): concurency::parallel_for and more https://msdn.microsoft.com/en-us/library/dd492819.aspx
posix : pthread library
as well as boost::thread, tbb ( https://www.threadingbuildingblocks.org/ )
And in general, a bunch of all sorts of solutions.

Answer 2

If Windows - CreateThread to help.
You can also use openCL/CUDA.

Answer 3

I advise you to read and learn in all subtleties.

Answer 4

One stream sorts another transforms? Or parallel sorting, and parallel transformation?
If the latter, then I would start by describing how I present a parallel solution in this case, because there are many options. If the former, then I would start with an example

int main(){
  std::vector<char> a = {'B', 'a'};
  std::thread t1(&mySort, &a);
  std::thread t2(&myToLower, &a);
  t1.join();
  t2.join();
}

Answer 5

in my opinion and openMP can help here
