초록

현재 널리 이용되는 멀티코어 프로세서 구조의 설계 초기에 그 성능을 분석하기 위하여 명령어 트레이스 모의실험을 이용하는 경우, 시간과 공간을 많이 차지하기 때문에 비실용적이다. 본 논문에서는 프로화일링 기법에 기반하는 통계적 모의실험에 의하여 다양한 하드웨어 사양을 갖는 멀티코어 프로세서의 성능을 측정하는 기법에 대하여 연구하였다. 이것을 위하여 SPEC 2000 벤치마크 프로그램의 특성을 통계적 프로화일링 기법으로 모델링하고 여기서 얻은 통계적 프로화일을 바탕으로 벤치마크 트레이스를 합성하여 멀티코어 프로세서에 대한 모의실험을 수행하였다. 그 결과, 통계적 모의실험에 의하여 측정한 성능이 명령어 트레이스 모의실험에 의하여 측정한 성능에 근접한 결과를 가져왔으며 모의실험 시간을 크게 단축시켰다.

When the trace-driven simulation is used for the performance analysis of widely used multicore processors in the initial design stage, much time and disk space is necessary. In this paper, statistical simulations are performed for a high performance multicore processor with various hardware configurations. For the experiment, SPEC2000 benchmarks programs are used for profiling and synthesizing new instruction traces. As a result, the performance obtained by our statistical simulation is comparable to that of the trace-driven simulation with the benefit of tremendous reduction in the simulation time.
