Opis:: The present paper discusses an effective adaptive methods suited for use in parallel environment. An in-house, parallel flow solver based on the residual distribution method is used for the solution of flow problems. Simulation is parallelized based on the domain decomposition approach. Adaptive changes to the mesh are achieved by two distinctive techniques. Mesh refinement is performed by dividing element edges and a subsequent application of pre defined splitting templates. Mesh regularization and derefinement is achieved through topology conserving node movement (r-adaptivity). Parallel implementations of an adaptive use the dynamic load balancing technique.

Opis:: Cloud environments made up of a large number of compute and storage servers provide ondemand services in a usage-based consumption model (pay-as-you-go). Load balancing is one of the major problems in the cloud. Indeed, the dynamics of demand requirements and QoS, as well as the variability of cloud resources and its provisioning models make difficult the operation of performance evaluation of the system. To face this issue and to ensure the viability of cloud computing, IT resources must be managed effectively by a dynamic monitoring of the current workload of virtual machines (VMs). In this study, we propose the design of a cloud services simulation tool at the infrastructure level based on cloud computing simulation platform named CloudSim. It allows real-time monitoring of a load of each VM in terms of CPU utilization, memory utilization and bandwidth utilization ratio. The result of this case study can be useful for carry out dynamic environment simulations for VMs monitoring and fast decision making that can be used in load balancing mechanisms.

Opis:: Dynamic data transfer demands are often being a challenge for present communication networks, as they appear in unpredictable time and must be satisfied prior to deadline. Important kind are the multi-target demands occurring in task of replication, backup, database synchronization or file transferring in pear-to-pear networks. Optimal scheduling usually depends of the nature of transport network. In the paper dynamic deadlinedriven multicast scheduling problem over elastic optical network is considered. Particularly, the method for improving link utilization by traffic balance for multicast demands is proposed. Few heuristic algorithms and results of experiments, proving the benefits of balancing concept are presented
