We are presenting a parallel GPU implementation of the Traveling Salesman Problem (TSP) solver. Our method is based on the iterative hill climbing algorithm first proposed by O'Neil et al., but modified in order to solve large instances of the problem. Our results show that GPU can be used to find an approximate solution of a problem which size is up to 6 thousand cities in a very efficient way achieving over 170 GFLOPS on a single TESLA C2050 card running thousands of independent threads. Due to computation-oriented architecture of GPUs, a more universal algorithm can be obtained with relatively little performance degradation.
