DRAM ECC error이것이 어디서 왔는지 모르겠습니다 . 어쩌면 내 마더보드, CPU 모델 또는 버전이 호환되지 않을 수도 있나요 Intel compiler SDK?
이러한 오류는 실행 중 약 5분마다 발생합니다.
저는 Intel 컴파일러 버전을 사용하고 있습니다 compilers_and_libraries_2020.1.217.
공식 Open-MPI Debian 10 저장소 버전에서 MPI를 사용하여 컴파일할 때도 동일한 오류 메시지가 나타났습니다.
BIOS에 변경해야 할 옵션이 있지만 확실하지 않습니다.
누구든지 이 문제를 해결할 아이디어가 있다면 알려주는 것이 좋습니다.
답변1
메모리에 문제가 있는 것 같습니다. 하드웨어 문제입니다. 오랫동안 memtest를 실행하거나 메모리 스틱을 교체하고 애플리케이션을 다시 시도해 보는 것이 좋습니다. 응용프로그램이 결함이 있는 섹터에 액세스하기 위해 너무 많은 메모리를 할당했을 수 있습니다.
