  Over the past two decades, PC speeds have increased from a few instructions per second to several million instructions per second. The tremendous speed of today's networks as well as the increasing need for high-performance systems has made researchers interested in parallel and distributed computing. The rapid growth of distributed systems has led to a variety of problems. The most important problem that has been addressed by many researchers is the task allocation in such environments in order to obtain effective system efficiency. The task allocation problem is, except in a few specific cases, an NP-complete problem; so, heuristic methods are used to achieve suboptimal solutions in the desired time. Although different methods have been used in research, finding an effective and efficient method for this problem is still needed and desirable. This study used a parallel genetic algorithm to find the optimal solution for allocating a graph of tasks to the processors in a distributed system. The results showed that the proposed algorithm can provide optimal or near-optimal allocations for problems of different sizes. Also, the proposed method was able to solve problems of large and medium-size in a much faster time than traditional genetic algorithm with super linear speedup. Manuscript profile

  In distributed systems, due to performing remote procedure calls, there is the possibility of generating orphan processes. Actually orphan processes are remote computations which their callers are crashed for any reason. The existence of orphan computations are not desirable because they waist resources and also there is the possibility that they see inconsistent situations in shared data. In this paper, a new approach in order to detect and eliminate orphan processes is presented. Proposed approach has significant advantages over existing methods in this area. The main advantages of this method are as follows: detection and elimination of all remote children and grandchildren of orphan process, few numbers of communication messages, no decrease in efficiency, load balancing and increase in fault tolerance.
