Durham University Implements CoolIT’s Direct Liquid Cooling Technology in the Cosmology Machine-8 Supercomputer

Durham University Elevates Scientific Computing with CoolIT’s Advanced Liquid Cooling in the COSMA-8 Supercomputer Launch.

[Calgary, Alberta, Canada, and Durham, United Kingdom – October 13, 2023] – The Institute for Computational Cosmology (ICC) at Durham University has officially inaugurated the Cosmology Machine-8 (COSMA-8) supercomputer on Friday, 13th October. This remarkable infrastructure, part of the National Infrastructure DiRAC facility (DiRAC) incorporates CoolIT’s state-of-the-art Direct Liquid Cooling (DLC) technology, making it one of the largest supercomputers in the UK committed to pioneering scientific exploration.

Hosted by the Institute for Computational Cosmology at Durham University on behalf of the DiRAC HPC facility, COSMA 8 is set to take center stage as part of the DiRAC Memory Intensive service. This powerful tool will empower scientists to further explore the realms of astronomy and particle physics through extensive simulations.

CoolIT Systems is the industry-leading provider of efficient Direct Liquid Cooling (DLC) and Rear Door Heat Exchangers (RDHx) that enable heat reuse and help customers meet key Environmental, Social, and Governance (ESG) targets. CoolIT‘s DLC technology is featured as a factory-installed, warranty-approved feature from most major servers OEMs.

From its early Direct Liquid Cooling investment in 2020 with 32 nodes Proof of Concept, the ICC at Durham University has progressively expanded its capabilities, currently boasting 10 racks of CoolIT’s DLC, which is essential for achieving the computational power and memory required for its cutting-edge cosmology simulations.

Dominik Dziarczykowski, CoolIT’s Global Channel Sales Manager, expressed, “Collaborating with Durham University and DiRAC on the COSMA-8 project exemplifies the efficiency, scalability, and transformative potential of Direct Liquid Cooling. Not only has it empowered Durham to achieve their ambitious computational objectives, but it’s also a great example of how Data Centers can be modernized to ensure the sustainable and energy-efficient trajectory for modern infrastructure globally.”

The key benefits of incorporating CoolIT’s DLC technology include the university’s ability to maintain cooling water at elevated temperatures, which many other systems cannot achieve. Without DLC, Durham would have faced challenges in achieving the same computational density. The COSMA-8 system uniquely integrates CoolIT’s DLC with the Rear Door Heat Exchanger system, creating a synergistic cooling solution that effectively manages and dissipates heat.

Dr. Alastair Basden, Head of the DiRAC Memory Intensive HPC Service at Durham University and co-chair of the DiRAC Technical Directorate, elaborated, “COSMA-8 is a testament to our dedication to unraveling the mysteries of our universe. From simulating the Big Bang to understanding the intricacies of black holes, this machine is a powerhouse. Its memory-intensive service, tailored for cosmology simulations, underscores our commitment to pushing the boundaries of knowledge.”

The substantial investment in COSMA-8, approximately 10 million pounds, was funded by UK Research & Innovation (UKRI) via the World Class Laboratories funding scheme, and the Digital Research Infrastructure funding scheme, administered by the Science and Technology Facilities Council. Notably, CoolIT collaborated with Dell on this project, delivering a comprehensive product portfolio including the CoolIT CHx750s and Rear Door Heat Exchangers.

The opening ceremony for the COSMA-8 Systems was graced by Chi Onwurah, MP for Newcastle upon Tyne Central and Shadow Minister for Business, Energy and Industrial Strategy, further underscoring the national significance of this project.
