我不知道这些DRAM ECC error来自哪里，也许我的主板、CPU 型号或版本不兼容Intel compiler SDK？
这些错误在执行过程中大约每 5 分钟出现一次。
我使用的是英特尔编译器版本compilers_and_libraries_2020.1.217。
当我从官方 Open-MPI Debian 10 存储库版本使用 MPI 进行编译时，我也遇到了相同的错误消息。
我应该修改 BIOS 中的一个选项，但我不确定。
如果有人有解决这个问题的想法，那么告诉它就好了。
答案1
看来你的内存有问题，这是一个硬件问题。我建议您长时间运行 memtest 或更换内存条并再次尝试您的应用程序。可能是应用程序分配了过多的内存来访问故障扇区。
