WUTR Collaboration

Project Overview

WUTR Project Overview

A ground-breaking collaboration showcasing how CodeZero's design, architecture, and optimisation skills are revolutionising High-Performance Computing (HPC) for Computational Fluid Dynamics (CFD).

WUTR High Performance Computing Challenge

The Challenge: Bottlenecks in Race Car Design

Warsaw University of Technology Racing (WUTR), a competitive Formula Student team, faced significant computational constraints in their race car design process. Their aerodynamics department, critical for performance, was running over 30 CFD simulation cases weekly, with each case demanding 6-8 hours on limited university CPU-based HPC resources.

This bottleneck severely restricted their ability to iterate designs and optimize aerodynamic performance. "Using all of the computing power provided to us by Code Zero we can reach a new high in our simulations and rise to the highest level of our capabilities." – Benedict, Aerodynamicist, WUT Racing.

WUTR Immersion Cooling Approach

The Solution: World-First Immersed GPU-Powered CFD

CodeZero implemented a cutting-edge, sustainable HPC solution leveraging liquid immersion cooling. This project marks another world first: running Ansys Fluent CFD simulations on Immersed GPUs.

Utilizing just a single virtual machine on our Nutanix-powered Dell R750 cluster (funded by Intel), CodeZero configured:

  • 64 CPU Cores
  • 128GB RAM
  • A single Nvidia A40 GPU (with GPU passthrough)

The key to this success lies in our optimised architecture, pulling resources from a single host to maximize performance and efficiency, running in a state-of-the-art immersion cooling environment.

WUTR Project Results

The Impact: Triple the Speed, Double the Design Iterations

CodeZero's immersed GPU platform delivered transformative results for WUT Racing:

  • 3x Faster Simulations: Aerodynamics simulations on their Formula Student car now run three times quicker than on the university's entire HPC cluster.
  • Increased Capacity: The team can now run at least twice as many simulations per day, significantly accelerating their design and development cycle.
  • Optimal Performance & Sustainability: The Nvidia A40 GPU operates at 96-100% utilization while maintaining an incredibly stable 45°C thanks to the immersion cooling technology.
  • Cost-Effective & Sustainable: The solution provides enterprise-grade HPC capabilities at a reduced Total Cost of Ownership (TCO) and supports environmental goals by enabling 100% heat capture and repurposing from the immersion rack.

"Our platform has delivered their CFD simulation three times quicker using the GPU in immersion than their entire HPC cluster." – CodeZero Representative.

Ecosystem Collaboration: The Power of Partnership

This project wouldn't have been possible without the invaluable support of our ecosystem partners.

  • GRC (Green Revolution Cooling): Providing leading immersion cooling technology.
  • BP Castrol: Supplying advanced immersion cooling fluid for optimal thermal management and power efficiency.
  • CADFEM UK: Delivering an Enterprise Ansys Fluent license with HPC packs and crucial technical guidance for GPU optimization.
  • CentersquareDC & UNICOM Engineering: Key infrastructure and integration support.

This collaboration demonstrates how strategic partnerships can remove computational barriers and democratize access to cutting-edge technology.

Future Outlook: Driving Performance Further

This case study kicks off an exciting 12 months for both WUTR and CodeZero. We aim to drive further improvements to WUTR's race car performance by enabling more complex simulations. Future plans include scaling to a full cluster to run 140 million cell mesh simulations, comparable to the capabilities of leading Formula 1 teams.

CodeZero is committed to delivering innovative, sustainable, and cost-effective HPC solutions that empower educational institutions and businesses to overcome computational challenges and achieve breakthrough results.
