Assistive Technologies

The operation of the PERUN supercomputer requires a precisely engineered technical foundation that ensures reliable, secure, and energy-efficient performance.

These supporting technologies form an integral part of the Supercomputing Center’s infrastructure at the Technical University of Košice (TUKE).
They include the power supply system, advanced cooling infrastructure, and environmental control mechanisms that maintain long-term stability of the data hall.

1. Data Center Power Supply

The power system of the HPC PERUN environment is designed for high reliability, redundancy, and uninterrupted operation.

  • Electrical energy is supplied from two independent transformers, ensuring operational stability even if one branch fails.
  • Backup power is provided by a Vertiv UPS system with battery arrays, which maintains power during short outages.
  • For extended resilience, the system includes a CGM motor generator (900 kVA) that activates when needed.

This configuration ensures seamless transitions between power sources, preventing interruptions to computing nodes, storage systems, and networking equipment.

2. HPC Cooling System

Given the extremely high computational density, the PERUN cooling system is designed as a redundant, automated, water-based cooling solution.

  • The primary cooling medium is a water–glycol mixture, providing stable thermal management even under extreme load.
  • Cooling is delivered by three STULZ chillers, operating outside the building in redundant automatic mode.

Cooling is divided into two circuits:

  • Cold-water circuit – cools HPE ARC in-rack units that remove heat directly from high-density racks.
  • Warm-water circuit – circulates through heat exchangers, mixers, and manifolds to cool both the universal and accelerated GPU partitions.

Together, these components deliver precise thermal balance and maximize energy efficiency.

3. Management of Data Center Environment

The HVAC system ensures:

  • proper air exchange
  • stable temperature
  • controlled humidity
  • long-term microclimatic stability

It works in coordination with the water-based cooling system to maintain optimal environmental conditions for all computing technologies.

An automated management layer continuously monitors environmental parameters and dynamically adjusts cooling based on real-time system load.
