Thereof, how many threads can run at once?
In context of Operating System, only one thread can run at a time. Even your application has multiple threads, at a time one of the thread will be executing and rest will be waiting for their turn.
Similarly, how do I know my CPU thread count? First tab. You'll see how many cores it has listed and near the bottom it'll have yes or no for "hyper threading technology". If yes, double your cores. If no, your cores = your threads.
Subsequently, question is, how many is too many threads?
Try it out with 1 thread per CPU core, try it out with 5 threads per CPU core, compare the results, move forward. However, there are some heuristics you can use to get started. Plus, if you're new to this, it's good to have a ballpark idea of what's sane. Is 100 threads too many?
Can two threads run simultaneously?
Yes, A program can run two threads at the same time. it is called Multi threading.
