SADLBoIB: Self-Adaptive Dynamic Load Balance over InfiniBand

InfiniBand, as a new industry standard of advanced interconnection architecture for high-performance computing and data-center applications, provides superior performance, QoS, and management features compared with other classic high-speed interconnections, e.g., Myrinet, GigE and etc. However, how to design and implement a load balancing strategy in an InfiniBand connected system which can make full use of the features of InfiniBand has not been deeply explored yet. This paper presents the self-adaptive dynamic load balance over InfiniBand (SADLBoIB), a load balancing system which efficiently utilizes RDMA-operation and one-side communication capabilities provided by InfiniBand to dramatically reduce load-balance messages overhead and improve the system reliabilities with a new self-management mechanism. Besides, the multi-level design model of SADLBoIB provides more configurability and customization than normal load-balance systems. Performance evaluation shows that compared with traditional load balancing implementation, SADLBoIB can shorten the communication times at least by half through the one-side communication provided by RDMA operation
