presentation of a comparative method for grid reliability

every year, with regard to rapid development of data, grid computing that is a kind of distributed computing system is that it has attracted the attention of most people and considerably taken into account. computing that cannot be done by huge computers can be performed by grid computing. if load balance is used, efficiency will increase in grid. resources have an important and effective role in grid efficiency. when resources are available and accessible, the access time and efficiency will improve. in this paper, swarm intelligence algorithm has been used and applied in grid in order to provide load balance. since grid environment is a dynamic environment, glowworm algorithm is used to provide load balance in sites. the results of algorithm simulation presented by matlab software show that, by using this algorithm, efficiency as well as reliability will increase in grid environment. also, this algorithm has been compared with two other algorithms in this field.
