We are concerned with the performance analysis of finite-source networks with users retrials (repeated calls) and two heterogeneous servers classes using Markov Chains Model. Emphasis is done on comparison of two servers allocation disciplines, namely the Random Server discipline and the Fastest Free Server discipline. It is known that an analytical solution of the corresponding retrial queueing model...
This paper addresses the problem of scheduling and load balancing in heterogeneous computational grids. We proposed a two-level load balancing policy for the multi-cluster grid environment where computational resources are dispersed in different administrative domains or clusters which are located in different local area networks. The proposed load balancing policy takes into account the heterogeneity...
