Abstract: Grid evaluation approaches usually focus on some
special aspects of grid environment and there have been few researches on a
technique which is able to comprehensively evaluate a grid system in terms of
its performance. In this paper an algorithm is proposed in order to evaluate
the performance of grid environment based on4 metrics of reliability, task
execution time, resource utilization rate and load balance level. In the
proposed algorithm, a new method for evaluating the resource utilization rate
has been presented. Also, in the paper an application of Technique for Order-Preference
by Similarity to Ideal Solution (TOPSIS) is presented in order to choose the
most efficient system based on these 4 metrics. Algorithm and TOPSIS
performances are demonstrated through analytical and numerical examples. Then,
using simulation, it has been demonstrated that the proposed algorithm
estimates the amount of utilization rate with high accuracy. Using the
suggested approach, one can choose the most efficient algorithm so that a
compromise is established between managers’ and users’ requests.
