报告题目Maximum Elastic Scheduling Based on the Hose Model

报告人Prof. Jie Wu, Temple University 美国天普大学吴杰教授




Resource allocation is important design issue in the cloud-based data center network (DCN) in maximizing its efficiency. We consider provisioning the maximum admissible load (MAL) of virtual machines (VMs) in physical machines (PMs) in the tree-based DCN using the hose model for communication. The limitation of static load distribution is that it assigns tasks to nodes in a once-and-for-all manner, and thus, requires a priori knowledge of program behavior. To avoid load redistribution during a run time where the load grows, we introduce maximum elasticity scheduling, which has the maximum growth potential subject to the node and link capacities. Given a tree-based DCN, we aim to find the schedule with the maximum elasticity across both nodes and links. We have found a distributed linear solution based on message passing, and we discussed several extensions. Various simulations and test-bed experiments have been conducted using the proposed elastic scheduling.
