D6.2: Final Report on the PRACE Operational Services

The objective of this deliverable is to present the activity done in the reporting period (May 2018 - April 2019) to operate and coordinate the common PRACE Operational services, foreseen by task 6.1 of WP6 in PRACE-5IP project. The operation of the PRACE distributed HPC infrastructure involves the coordination of a set of services which integrate the Tier-0 systems and a number of national Tier-1 systems, providing services for Tier-0, in a “single” pan-european HPC infrastructure.
This work is the continuation of the work done by task 6.1 in the previous PRACE-IP projects to give continuity to the PRACE Operational services for the HPC Eco-system.
Eight Tier-0 systems were operational in the second year of the PRACE-5IP project period:

• JUWELS at GCS@JUELICH;
• IRENE SKL at GENCI@CEA;
• IRENE KNL at GENCI@CEA;
• HAZELHEN at GCS@HLRS;
• SuperMUC phase2 at GCS@LRZ;
• MARCONI (BDW & KNL) at CINECA;
• MareNostrum4 at BSC;
• PizDaint at ETHZurich@CSCS

Furthermore, operational support has been provided to 23 national Tier-1 systems that provide services for Tier-0 (i.e. used from SMEs for the SHAPE activity, or as stepping stone towards Tier-0 systems, or to prototypes and asses new operational services). These Tier-1 systems are distributed among 14 different countries, ensuring a wide distribution of the European HPC eco-system.
Based on the procedures for incident and change management the complete set of PRACE common services as defined in the Service Catalogue (Networking, Data, Compute, AAA and Security, User, Monitoring and Generic) have been operated and monitored on a day-by-day basis to assure continuity and integrity of the services.
The Security Forum, responsible for all security related activities, is also coordinated by task 6.1, with periodic teleconferences to monitor the infrastructure and prevent possible incidents which could cause vulnerability on the PRACE RI. The PRACE CSIRT team has been established and is now in status of listed – a prerequisite to be fully Accredited to GÉANT’s Trusted Introducer program. The full accreditation is ongoing.
