CRESCO5F

Cluster Features

The CRESCO5F cluster located in Frascati is a computing system composed of 8 nodes, some equipped with GPU accelerators and one with FPGA.

Node configuration:

  • cresco5fx001 : front-end node with 2 NVIDIA A100 GPUs

  • cresco5fx002 : node with 2 NVIDIA A100 GPUs

  • cresco5fx003–004 : nodes with 1 NVIDIA A100 GPU

  • cresco5fx007–009 : nodes without GPU and without FPGA

  • cresco5fx010 : node with Intel FPGA

General hardware configuration of the nodes:

  • 2 sockets with 16 cores AMD EPYC 7313 processors at 3.0 GHz

  • 256 GB RAM (8 GB per core)

  • 1 × 500 GB SATA II disk

  • InfiniBand MLX5 100 Gb/s interface (≈80 Gb/s effective bandwidth)

  • Two 10 GbE interfaces

  • BMC/IPMI support and software for remote console management

The cluster provides 256 CPU cores interconnected through a low-latency network based on Mellanox InfiniBand EDR (100 Gb/s) managed by a Mellanox switch.

Nodes run the operating system:

Rocky Linux 8.5

This is a newer major release compared to CentOS 7.3 (CRESCO6) and CentOS 7.8 (CRESCO4). Users are therefore advised to verify the portability of their codes and recompile them if necessary.

Each node also provides a local scratch disk: /tempwork

The local scratch area is 1 TB NVMe.

Note

Access to the /tempwork area must be requested through a support ticket.
