In cloud systems, big data must be partitioned and then stored over several data nodes (DNs) for being processed by virtual machines(VMs). Thus, there exists access latency among DNs and their assigned VMs. Meanwhile, the access latency also exists among the pairs of assigned VMs for the computing result collection. Different VM assignment strategies for DNs result in different access latency. It...
Graph partitioning has been widely applied in cloud computing, data centres, virtual machine scheduling, hardware/software co-design, and VLSI circuit design, etc. The general graph partitioning problem is known to be NP-hard. This paper investigates how to partition the vertex set of an undirected weighted graph into two disjoint subsets, such that the total vertex-weights of the two subsets are...
