Allocating Tasks in Multi-core Processor based Parallel System

After a discussion of the task allocation problem in multi-core processor based parallel system, this paper gives the task allocation model, and proposes an iteration-based heuristic algorithm, which is composed of two rounds of operations, in which the processes are assigned to processing nodes in the first round and threads in process are assigned to processor cores in the second round respectively. Each round of operation partitions the task interaction graph by iterations with backtracking. Evaluation result shows that the algorithm can find near-optimal solutions in reasonable time, and behaves better than genetic algorithm when the number of threads increases, since it can find solutions in much less time than genetic algorithm.
