EN The new European HPC facility for Fusion is in operation since July 2016. It replaces, for European fusionresearchers, the Helios supercomputer installed in Japan in the context of the Broader Approach agreement. Thesupercomputer is hosted at CINECA and it is a fraction of the MARCONI system. Thanks to a customizedtechnical project done by ENEA, in a joint development agreement with CINECA, the European community offusion modelling can exploit the latest available CPU technologies, following the CINECA HPC roadmap towards50 PFlops planned for 2019. The MARCONI Fusion fraction is being delivered in two phases: thefirst one, 1PFlops of CPU multi-core architecture based on the Intel Broadwell processors, is already in operation since July2016, and the second one, 5 PFlops of the same architecture based on the INTEL Skylake processors, will bedeployed in July 2017. Furthermore the project includes 1 PFlops of the third generation of Intel Xeon Phi many-core architecture (Knights Landing generation).Within this framework, ENEA/CINECA provides, in addition, the operation support of the Gateway infra-structure of EUROFusion Work-Package Code Development. A new Gateway HPC system is in operation atCINECA since Jan. 2017 thanks to the data migration and software porting activities carried out by ENEA/CINECA team together with the Core Programming Team of the Infrastructure and Support Activity workpackage from EUROfusion. The new Gateway infrastructure is tightly coupled with the MARCONI Fusionfraction, sharing the same 100 Gbps low-latency network based on the Intel OmniPath technology.The paper describes the technical details and the performances of MARCONI, one of the largest HPCOmniPath based infrastructure.
