The Prime Counting Function model uses the trial division algorithm to compute the number of primes less than or equal to the number n. Although the trial division algorithm is inefficient, we use it to perform a lengthy calculation while a standard EJS simulation thread accumulates and plots data from the parallel computation. Users can vary the number of independent threads and observe the computational time.

The Prime Counting Function Model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the model's jar file will run the simulation if Java is installed.

Please note that this resource requires
at least version 1.6 of
