The article introduces the program application for seeking binary signals of specified bit length that have specified correlative properties. The application seeks these codes using parallel (multithreaded) permutation of the possible values from all of the range specified by a bit length. The article contains the results of researches of speed parameters of the permutator working in single–threaded and multithreaded modes. Analysis was made for multithreaded specific conditions of speed reductions. The researches are made according to the priority national project "Education" in the centre of high performance computations of the Far Eastern National Technical University. The centre allows parallel computations in remote access.
