동시 다중 쓰레딩 마이크로프로세서를 위한 스케쥴링 알고리즘의 성능 평가

Abstract

Recently, many processor manufacturers have implemented simultaneous multi threading technology, which can simultaneously execute independent threads in one processor cycle, as a way of increasing processor efficiency, and, one particular example is Hyper Threading. Hyper Threading technology, which enables many logical processors to reside a physical processor, differs from the current multiprocessing environment, which has many independent processors, and calls for a particular work assignment method optimized for Hyper Threading environment. Thus, in this paper, We have proposed a scheduling algorithm compatible with Hyper Threading technology and analyzed its performance using various methods. As a result, we shall expect its efficient performance by properly understanding and managing Hyper Threading system.
