System Architecture
Compute Nodes:
- 636 computing nodes each 2 x CPU Intel CascadeLake 8260, with 24 cores each, 2.4 GHz, 384GB RAM, subdivided in:
- 422 standard nodes ("thin nodes") 480 GB SSD
- 180 data processing nodes ("fat nodes") 2TB SSD, 3TB Intel Optane
- 34 GPU nodes (visualization "viz" ) with 2x NVIDIA GPU V100 with 100Gbs Infiniband interconnection and 2TB SSD.
- 77 computing servers OpenStack for cloud computing (ADA CLOUD), 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.
- 1 PB Ceph storage for Cloud (full NVMe/SSD)
- 720 TB fast storage (IME DDN solution)
Login and Service nodes:
10 login nodes and 5 service nodes. 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.
Access
All the login nodes have an identical environment and can be reached with SSH (Secure Shell) protocol using the "collective" hostname:
