CPU 0번 메모리 고갈 문제

[HanMinGyun]

• mvrlu_bench 실험진행중 (user-level)
  • thread개수 16개 이상일 경우 실험이 종료되지않는 문제가 발생함

[MadPlayer]

thread 개수가 32개 이상 늘어나면 mvrlu_bench가 종료되지 않는 문제가 param.h의 time quantum값을 10으로 했을 때와 같은 이유라고 생각되어서 scalefs에서 qemu로 param.h의 time quantum을 10으로 하고 mvrlu_bench를 실행하여 block된 상태에서 메모리를 지속적으로 확인한 결과입니다. CPU 0번의 메모리가 지속적으로 고갈되는 것을 알 수 있었습니다.

@MadPlayer kbench나 application benchmark 실행시 특정 코어의 메모리 고갈이 성능에 크게 영향을 미치는건지 알아볼 필요가 있겠네요?

[bigsys-gnu]

@MadPlayer 창희학생 이게 좀전에 얘기한 CPU 0번 메모리 고갈 문제 로그에요? CPU 0번 메모리가 줄어드네요?

@MadPlayer 창희학생 이게 좀전에 얘기한 CPU 0번 메모리 고갈 문제 로그에요? CPU 0번 메모리가 줄어드네요?

예 맞습니다 이때와 수정된 코드가 있어서 새로 실행해보겠습니다

@MadPlayer free page가 없는 경우인가요? 아래 두가지 케이스에서 숫자들이 의미하는것이 뭔지 확인이 필요해 보여요.
