XC50システム利用者各位

いつも国立天文台・天文シミュレーションプロジェクトのXC50システムをご利用いただき、誠にありがとうございます。

XC50システムにおきまして、大規模なジョブを実行した際にI/Oによりネットワーク通信での遅延が生じてLustreファイルシステムがタイムアウトとなる現象が確認されました。
このエラーが発生したことにより、XC50システムより出力されたファイルの一部が破損した事例が報告されています。
以下に5/29の定期保守作業以降に記録されたエラーログとそのノードで実行されていたジョブを記載いたしますので、
該当するジョブを投入していたユーザは出力ファイルの確認をお願いいたします。

また、ログインノードにおいて生じたエラーにつきましてはユーザの特定ができませんでした。
エラーの発生原因もまだ完全に特定できてはおりませんので、全てのユーザの皆様に今一度出力ファイルに破損がないかをご確認いただきますようお願い申し上げます。
あわせて、本エラーによる被害規模を把握するため、出力ファイルに破損が確認された場合にはお手数ですがご報告いただけますと幸いです。
