【Abstract】 The SMT GA algorithm, which is a genetic algorithm for task mapping and scheduling in Heterogeneous Computing Systems (HCS), is introduced. First the task scheduling problem for HCS is described. Then the structure of the algorithm, chromosome design, the method to generate scheduling solution from a chromosome, the design of fitness function, the crossover and mutation operator design, are discussed respectively. In the end, the algorithm realization, experiment result analysis and the conclusions are presented.更多还原
