DRAM ECC errorこれがどこから来たのかわかりません。おそらく私のマザーボード、CPUモデル、またはバージョンが互換性がない可能性がありますかIntel compiler SDK？
これらのエラーは実行中に約5分ごとに発生します。
私はIntelコンパイラのバージョンを使用していますcompilers_and_libraries_2020.1.217。
公式のOpen-MPI Debian 10リポジトリバージョンでMPIを使用してコンパイルすると、同じエラーメッセージが表示されました。
BIOSに変更する必要があるオプションがありますが、わかりません。
誰でもこの問題を解決するアイデアがある場合は、教えてください。
答え1
メモリに問題があるようです。ハードウェアの問題です。長い間memtestを実行するか、メモリースティックを交換してアプリケーションを再試行することをお勧めします。アプリケーションが欠陥のあるセクターにアクセスするために多すぎるメモリーを割り当てている可能性があります。
