The problems of simulation by using different Grid resource schedulers
are developed. A statistical analysis of real workflows Grid clusters,
calculated characteristics of the distribution of tasks which are used to
adjust the simulation model and subsequent simulation of the system. The results of the simulation Grid in the use of different values
of the characteristics of the workflows, resources, and periodicity of scheduling.
In order to optimize the scheduling algorithms are constructed regression of
the dependence between the calculated values of the performance metrics of Grid
systems. Showing the direction of improving the work proposed in a heuristic
scheduling algorithm based on changes in the intensity of the workflows and the
amount of system resources.
Keywords: algorithm, Grid-system, the laws of
distribution, the cluster, minimal cover, parameters of the model, the
scheduler, simulation.
