Galileo
Galileo 100
The new infrastructure GALILEO100, co-funded by the European ICEI (Interactive Computing e-Infrastructure) project and engineered by DELL is available to the Italian public and industrial researchers until September 2021.
It is the national Tier-1 system for scientific research.
System Architecture
Compute Nodes:
- 528 computing nodes each 2 x CPU Intel CascadeLake 8260, with 24 cores each, 2.4 GHz, 384GB RAM, subdivided in:
-
- 348 standard nodes (“thin nodes”) 480 GB SSD
- 180 data processing nodes (“fat nodes”) 2TB SSD, 3TB Intel Optane
- 36 GPU nodes with 2x NVIDIA GPU V100 with 100Gbs Infiniband interconnection and 2TB SSD.
-
- 77 computing server OpenStack for cloud computing, 2x CPU 8260 Intel CascadeLake, 24 cores, 2.4 GHz, 768 GB RAM, with 100Gbs Ethernet interconnection.
- 20 PB of active storage accessible from both cloud and HPC nodes.
- 5 PB of fast storage for HPC system.
- 1 PB Ceph storage for Cloud (full NVMe/SSD)
Login and Service nodes:
10 Login nodes are available. 5 service nodes for I/O and cluster management.
All the nodes are interconnected through an Infiniband network, with OPA v10.6, capable of a maximum bandwidth of 100Gbit/s between each pair of nodes.
