The HPC@PoliTO Infrastructure

The HPC@PoliTO infrastructure is currently made of two separate clusters. HACTAR is our legacy cluster, it was first deployed in 2015 and currently only used for light workloads by students teams and for teaching purposes. LEGION is our flagship cluster, it was first deployed in 2020 and underwent a major upgrade in 2024. It is used by research groups at Politecnico di Torino for their heavier workloads.

The High Performance Computing infrastructure is supported by two complementary storage systems: a high-capacity Network Attached Storage (NAS) to store users' homes and data and a lower-capacity BeeGFS parallel filesystem that provide a scratch space for IO intensive workloads that require parallel high-speed operations

LEGION is our flaghsip cluster, based on a high-bandwidth and low-latency RDMA network (Infiniband) it currently consists of 132 computing nodes, 34 of which are equipped with NVIDIA GPUs. The cluster currently aggregates 5420 CPU cores (Intel Xeon Gold), 60.4 TB of RAM, 108 NVIDIA A40, 4 NVIDIA A100 and 24 NVIDIA V100.
