一种多线程负载均衡分析方法研究
Research on analyzing load equilibrium of multi-threads
摘要
Abstract
In order to accurately analyze the load balance problem and improve the performance of OpenMP program, this paper defined the unit of load balance analysis and measured the degree of load imbalance with the adjusted efficiency of latency parallel, then proposed a method for monitoring, analyzing and adjusting OpenMP multi-thread load balance. It used an approach based on directive rewriting for instrumentation and obtaining performance data with the help of unfolding hidden synchronization operations and adjusted selectively OpenMP program at the side of load balance according to the adjusted efficiency of latency parallel. Experimental results demonstrate that the method is feasible and effective.关键词
