Marconi is the new Tier-0 system, co-designed by Cineca and based on the Lenovo NeXtScale platform, that substitutes the former IBM BG/Q system (FERMI). MARCONI, based on the next-generation of the Intel® Xeon Phi™ product family alongside with Intel® Xeon® processor E5-2600 v4 product family, offers the scientific community a technologically advanced and energy-efficient high performance computing system.
This achievement represents the first step of the Italian infrastructure development plan put forward by the Cineca governing bodies, aimed at supporting scientific research. The global plan entails an investment of Euro 50 million in two phases. The first, just started, will make available a computational power of about 20Pflop/s and a data storage capacity of more than 20 petabytes, which will go into production, reaching completion in the second half of 2017. The second phase will start during 2019, with a final goal to increase available computing power to approximately 50 to 60 Pflop/s by 2020.
The new system, logically named ‘MARCONI’, has been designed to be gradually completed in about 18 months, between mid 2016 and beginning 2018, according to a plan based on a series of updates:

Login nodes: 8 Login (3 available for regular users). Each one contains 2 x Intel Xeon Processor E5-2697 v4 with a clock of 2.30GHz and 128 GB of memory. Login nodes are shared between three partitions: A1 (BDW), A2 (KNL) and A3 (SKL). The three partitions are served by a single SLURM server.
In January 2020 the A2(KNL) partition has been upgraded to a new nVIDIA accelerated architecture. The MARCONI2 cluster is described in a separate document (UG3.1.1)

Marconi Network
Network type: new Intel Omnipath, 100 Gb/s. MARCONI is At the time of setup, MARCONI was the largest Omnipath cluster of in the world.
Network topology: Fat-tree 2:1 oversubscription tapering at the level of the core switches only.
Core Switches: 5 x OPA Core Switch "Sawtooth Forest", 768 ports each.
Edge Switch: 216 OPA Edge Switch "Eldorado Forest", 48 ports each.
Maximum system configuration: 5(opa) x 768 (ports) x 2 (tapering) → 7680 servers.
