The HPC@PoliTO initiative provides computing resources for research and teaching activities to hundreds of users at the Politecnico di Torino. HPC@PoliTO users include thesis students, PhD candidates, researchers, faculty members, and student groups across all departments of the Politecnico. HPC@PoliTO’s computing resources contribute to all major research areas active at the Politecnico di Torino, ranging from computational fluid dynamics to physical chemistry, and from bioinformatics to generative AI.
The HPC cluster “Legion” consolidates high-performance computing resources within a centralized infrastructure. Users access a common login interface, through which they can submit their workloads and choose among different specialized hardware options. Computing resources are shared among users via a dedicated scheduler, which manages job requests and allocates resources fairly.
The cluster is composed of 150 high-performance computing nodes:
- 98 CPU-based nodes (Intel Xeon Skylake & Sapphire Rapids)
- 52 GPU-based nodes (NVIDIA V100, A40 & A100)
Some key figures:
- 13.2 TB VRAM
- 60 TB RAM
- 1.8 PB flash storage
The computing nodes and storage systems are interconnected via a dedicated Infiniband network (200 Gb/s and 100 Gb/s) offering extremely high performance and very low latency, ensuring excellent scale-out even for the most demanding workloads.
The cluster is complemented by an additional internal Ethernet network with a 10 Gb/s bandwidth to provide user connectivity and support the operational management of the system.
