Consolidation and overbooking are two important methods to improve the resource utilization in cloud computing. In overbooking cloud environment, the resources occupied by virtual machine are restricted to guarantee performance fairness between multi-tenants. However, the interaction among co-host applications results in performance degradation because of the resource sharing and competition. Previous...
The most effective algorithms of solving large sparse linear system are Block Wiedemann and Block Lanczos, sparse matrix-vector multiplication iterations is the main process of these algorithms, to achieve parallel computing of its process, we have established three different parallel algorithm models and analyzed the characteristic features of their computing and communication, and through the analysis...
