4. 주의사항 / Error 항목
Vortex00.outorder0*.gcc.100M.ss 에 대해 압축을 푸는데 있어, 윈도우상에서 풀었을 경우
실행 1초만에 실행 완료  에러
Tar 파일 형태로 리눅스상에서 받아 직접 압축 해제후 실행  정상 실행 후 종료
절대경로 /edu/simplesim-3.0/ 에 입력파일 복사후 직접 실행시 sim-profile 명령 실행 오류
/edu/bin/ 에서 절대경로 ‘/edu/simplesim-3.0/sim-profile’ 명령 수행시 에러 없이 실행됨.

17. 결 론
Vortex00.outorderO0.gcc.100M.ss의 경우 예시된 수치와 상당히 상반된 결과를 발생하였다. 2회에 걸쳐 재 수행해 보았으나, 역시 같은 수치가 나온것을 볼때, 잘못된 결과는 아니라 본다.
Vortex00.outorderO0.gcc.100M.ss 과 Vortex00.outorderO1.gcc.100M.ss 사이의 상당히 많은 program text size의 크기가 줄었으며, 실행명령어의 수도 감소하였다. 이를 볼때, 최적화 레벨상태에 따른 프로그램 수행의 감소 상태를 확인할 수 있다. 그러나 Vortex00.outorderO1.gcc.100M.ss 과 Vortex00.outorderO2.gcc.100M.ss 사이의 경우, Program text size와 실행명령어의 차이는 미미하다.
