CURIE is a supercomputer of GENCI, located in France at the Très Grand Centre de Calcul (TGCC) operated by CEA near Paris. CURIE BULLx system composed by 5 040 compute blades (called thin nodes), each node having 2 octo core Intel SandyBridge EP processors 2.7 GHz, 4 GB/core (64 GB/node) and around 64 GB of local SSD acting as local /tmp. These nodes are interconnected through an Infiniband QDR network and accessing to a multi-layer Lustre parallel filesystem at 250 GB/s. The peak performance of the thin nodes partition is 1.7 Petaflops.

The successor of Curie is JOLIOT CURIE , with a first tranche starting service Q2 2018, will be a BULL Sequana system based on 9 compute cells integrated into 2 partitions:
– a SKL partition of 79 488 cores composed by 6 cells each containing 272 compute nodes with two 24-core Intel Skylake 8168 processors 2.7 GHz, 4 GB/core (192 GB/node). These 6 cells are interconnected by an Infiniband EDR 100 Gb/s high speed network.
– a KNL partition of 45 288 cores composed by 3 cells each containing 222 nodes with one Intel Knights Landing 7250 68-core 1.4 GHz manycore processor with 16 GB of high-speed memory (MCDRAM) and 96 GB of main memory. These 3 cells are interconnected by an BULL BXI 100 Gb/s high speed network.
– This configuration is completed with 5 fat nodes for pre/post processing (3 TB of memory each and a fast local storage based on NVMe) and 20 hybrid nodes used for remote visualisation.
– These resources are federated across a multi-layer shared Lustre parallel filesystem with a first level (/scratch) of more than 5 PB at 300 GB/s. The peak performance of this system will be close to 9 Petaflops

Italian supercomputer systems complement the PRACE infrastructure from spring 2012.

CINECA’s Tier-0 system named MARCONI provides access to PRACE users since July 2016. The MARCONI system is equipped with the new Intel Xeon processors and it has two different partitions:

  • Marconi – Broadwell (A1 partition) consists of ~7 Lenovo NeXtScale racks with 72 nodes per rack. Each node contains 2 Broadwell processors each with 18 cores and 128 GB of DDR4 RAM.
  • Marconi – KNL (A2 partition) was deployed at the end of 2016 and consists of 3600 Intel server nodes integrated by Lenovo. Each node contains 1 Intel Knights Landing processor with 68 cores, 16 GB of MCDRAM and 96 GB of DDR4 RAM.

The entire system is connected via the Intel OmniPath network. The global peak performance of  the Marconi system is 13 Petaflops. In Q3 2017 the MARCONI Broadwell partition will be replaced by a new one based on Intel Skylake processors and Lenovo Stark architecture, reaching a total computational power in excess of 20 Petaflops.

JPEG - 68.7 kbSuperMUC is the Tier-0 supercomputer at the Leibniz Supercomputing Centre (LRZ) in Garching, Germany. It provides resource to PRACE via the German Gauss Centre.

SuperMUC Phase 1 consists of 18 Thin Node Islands with Intel Sandy Bridge processors and one Fat Node Island with Intel Westmere processors. Each compute Island contains (512 compute nodes, each node having 16 physical cores) 8192 cores for the user applications. Each of these cores has approx. 1.6 GB/core available for running applications. Peak performance is 3.1 Petaflops. All compute nodes within an individual Island are connected via a fully non-blocking Infiniband network (FDR10 for the Thin Nodes and QDR for the Fat Nodes). A pruned tree network connects the Islands.

SuperMUC Phase 2 consists of 6 Islands based on Intel Haswell-EP processor technology (512 nodes/island, 28 physical cores/node and available memory 2.0 GB/core for applications, 3072 nodes, 3.6 PF). All compute nodes within an individual Island are connected via a fully non-blocking Infiniband network (FDR14). A pruned tree network connects the Islands. Both system phases share the same Parallel and Home filesystems.
