그러면 출력이 혼란스러울 것입니다. 동시에 실행하는 동안 출력이 순서대로 나오도록 하려면 어떻게 해야 합니까? 감사합니다.
답변1
해당 명령을 모두 분기하면 분기가 순서대로 실행되지 않으므로 STDOUT에 대한 출력이 순서대로 이루어지지 않습니다.
모든 csce.py호출을 개별 파일로 리디렉션한 다음 해당 파일을 추적할 수 있습니다. 어떤 파일이 어떤 프로세스를 나타내는지 이해하려면 파일 이름에 대한 루프 변수를 사용하십시오.
그러나 확장성과 제어를 위해 다음을 사용합니다.GNU 병렬시도해 볼 가치가 있을 수도 있습니다.
그런데 파일 이름은 *.dat호출 매개변수에 의존하지 않으므로 Python 스크립트의 작동 방식에 따라 스크립트를 호출할 때마다 파일 이름이 막히거나(덮어쓰기) 커질 수 있습니다.
답변2
예, Gnu 병렬은 잘 작동하지만 & 연산자를 통해 수행하려면 리소스가 동일한 stdout을 공유하므로 출력이 혼란스러워 보일 수 있으므로 포크된 프로세스는 리소스를 확보할 때만 실행된다는 점을 알아야 합니다. .
