Thanks to the NVIDIA Hopper architecture and its high-throughput interconnects, this partition provides exceptional performance for massively parallel workloads, neural-network training, and large-scale data modeling.

By combining these two components — the universal CPU partition and the accelerated GPU partition — the PERUN system enables optimal allocation of computing resources based on task requirements.

Its architecture ensures high performance, stability, and scalability to support research, education, and innovative technological projects.

• Total Performance: 10.7 PFlops (Rmax)

The PERUN Supercomputer is directly connected to a high-speed InfiniBand network and the HPC PERUN data storage system, enabling efficient data processing and full utilization of available computational power.
