碩士 === 國立成功大學 === 電機工程學系碩博士班 === 90 === In the distributed shared memory system, load balancing plays an important role to improve system efficiency. It dynamically adjusts workload distribution by the runtime collected system information, and the goal is to share various resources among nodes. In the early days, many researches about load balancing focus on CPU resources but do not take memory resources into account. Without this consideration, the additional time may arise due to costly memory access latency in some nodes that are low memory resources, and then the parallelism of program execution is down. So we consider the affection of the memory resource in our load balancing design; that is to say, the mechanism arranges workload distribution by both CPU and memory resource consideration. In our results show that load balancing with memory resource consideration reduces the system waiting time to increase parallelism, and our design has better system improvement compared with that of only one resource consideration. We also show that the overhead is low in our design.
