Description
The KEK Central Computer System (KEKCC) is a computer service and facility that provides large-scale computer resources, including Grid and Cloud computing systems and essential IT services, such as e-mail and web services.
Following the procurement policy for the large-scale computer system requested by the Japanese government, we replace the entire system once every four or sometimes five years. The current system has replaced the previous system and has been in production since September 2020, and decommissioning will be planned to begin in Q3 of 2024.
During about 30 months of operation in the current system, we have decommissioned some legacy Grid services, like LFC, and migrated some Grid services to the newer operating system, CentOS7. In this talk, we would like to share our experiences and challenges regarding Grid services introduced in the KEKCC. Also, we will review the ongoing activity to enable Grid services in the token-only environment.
