D6.2.1: First Annual Integration Report

This report describes the activities of Task 6.2 (WP6): Integration and upgrade of new Tier-0 and Tier-1 systems.
A comprehensive procedure for monitoring and reporting the upgrade of a system in PRACE has been designed and tested. This procedure for the upgrade of a system must guarantee as much as possible an undisturbed migration of the PRACE services, with minimal impact on the services at other sites. It has been designed to be applied both for Tier-0 and Tier-1 systems. The procedure has been successfully applied for the upgrade of three systems: MareNostrum at BSC from Tier-1 to Tier-0, which is reported in this document, and Cartesius at SURFsara and SiSu at CSC. The upgrades of the latter two are both for Tier-1 systems and are managed by PRACE-2IP as part of the operations of the Tier-1 infrastructure. The experience of these upgrades is used for improving the procedure itself. The upgrade procedure, as discussed in this document, consists of nine steps that should cover all possible scenarios.
Two new Tier-0 systems have successfully been taken in service in this project period, an IBM BlueGene/Q system at CINECA, Italy, and an IBM iDataPlex DX360M4 system at BSC, Spain. Both these systems replaced an existing Tier-1 system.
This task also started the integration of two new Tier-1 sites, NIIF in Hungary and CaSToRC on Cyprus. The procedure being used to integrate these systems is the same used by other Tier-1 systems in PRACE-2IP.
