CSC/UPM/AMD: World-class energy efficiency at Kajaani


A recognized pioneer in the sustainable development of ICT services, CSC is committed to promoting climate objectives in all of its operations. Thus, by supporting the green transition, reducing its carbon footprint and achieving positive green growth, CSC aims to minimize the environmental impact caused by its activities.

The company is working with UPM and AMD to upgrade its data center in Kajaani/Finland to deliver world-class energy efficiency. “The key to energy efficiency is that all energy consumed by data centers is spent on meaningful activities, i.e. computing power with low PUE. And the residual heat generated by the DC operator is used sustainably. It also significantly reduces energy costs,” says Jukka-Pekka Partanen, Data Center Ecosystem Director at CSC – IT Center for Science.

A modern business park in Kajaani, based on a former UPM paper mill, hosts over 40 customers, including data centers. Kajaani Data Center Program has the ambition to further grow its customer base with domestic and international clients.

“We want to create a synergy of benefits within the ecosystem for data centers and related businesses. We also want to broaden and deepen knowledge on data invocation, machine learning and artificial intelligence (AI), as well as support the visibility, reputation work, internationalization and business of Kajaani and the Greater Kainuu Region,” says Partanen.


Founded in 1971, CSC – IT Center for Science is a Finnish center of expertise in information technology. It is owned by the Finnish state and higher education institutions. CSC’s mission is to provide high quality ICT expert services – internationally – for higher education institutions, research institutes, culture, public administration and business.

CSC’s Kajaani Data Center Program was created to attract new domestic and/or international data center customers to Kajaani, as well as to create synergies within its ecosystem for data centers; broaden and deepen their knowledge of data invocation, machine learning and artificial intelligence; and support Kainuu’s visibility, reputation work, internationalization and business.


Founded in 1996, UPM is a large Finnish forestry company. UPM supplies a variety of products made from wood. Due to structural changes in papermaking, many of the organization’s stationery facilities are empty. UPM aims to introduce new ways of operating in these premises. UPM is dedicated to creating a future beyond fossils.

Although its main business is not real estate, after the closure of its stationery business, UPM has been dedicated to developing its real estate in locations suitable for other uses.


Founded in 1969, AMD has been at the forefront of innovation for 50 years in high-performance computing, graphics and visualization technologies, the building blocks of games, immersive platforms and data centers.

AMD employees are focused on creating cutting-edge, high-performance, adaptive products that push the boundaries of what’s possible. Billions of people, leading Fortune 500 companies and leading scientific research institutes around the world trust AMD technology every day to improve the way they live, work and play.

Create a safe, secure and energy-efficient ecosystem

Working collaboratively, CSC has developed a strong partnership with UPM and AMD to develop a safe, secure and energy efficient data center ecosystem at Kajaani.

“AMD strongly believes in environmental sustainability and energy efficiency improvement efforts. We have announced an ambitious goal to increase the energy efficiency of AMD processors and accelerators 30x between 2020 and 2025,” said Andrew Dieckmann, Corporate VP & GM for the Data Center GPU Business Unit at AMD. “We are also committed to creating a future beyond fossil fuels. Sustainability is at the core of our business,” adds Hannu Havanka, Vice President Real Estate at UPM Kymmene Oyj.

As part of their joint efforts on this front, the three partners support the EuroHPC joint venture, which operates and develops high-end supercomputers to strengthen Europe’s scientific excellence and industrial strength, and to support the transformation digitalisation of the EU economy.


One of these supercomputers is located in Kajaani. “LUMI was ranked third on the Green500 list, released on May 30, 2022. The supercomputer was built on environmental sustainability and world-class cost efficiency criteria. It helps the European ICT sector drive the greener and more cost-effective operations needed to achieve the EU’s ambitious climate goals and pave the way for the green transition. With the smallest possible environmental burden and the lowest cost to European taxpayers, LUMI is second to none,” says Partanen.

The LUMI system leverages a consistent CPU and GPU interconnect using AMD Infinity Fabric™ technology, which provides high-speed, low-latency interconnect, unified memory for applications, and improves efficiency.

“Applications using HPL code take advantage of this coherent interconnect to run the serial portions of the code in the CPU, with the parallel portions of the code on the GPUs making efficient use of both the high performance AMD EPYC™ CPU cores and from AMD Instinct™. GPU computing units. It also makes it possible to intelligently manage the movement of data, thereby simplifying programmability and facilitating the adoption of GPUs for HPC applications,” says Dieckmann.

He continues, “The LUMI system also has a downstream network card directly attached to each of the Instinct MI250X GPUs that operates at 25 Gbps, enabling low-latency messaging from GPUs to off-node node, helping to overlap the calculation and communication, thus using the system efficiently. and improving overall performance. These innovations are key to delivering a system capable of delivering 152 peak PF and 62.7 GFlop/W, earning #3 spots in the Top500 and Green500.

Partanen adds: “The LUMI supercomputer is a truly unique investment in the Kajaani data center. It is a modern and efficient project which was completed on time and on budget. Kajaani is a proven location suitable for data centers and data center ecosystems. As proof, the LUMI data center has already won three international competitions in the category of the most innovative projects.

Make Kajaani and her abilities known

A unique data center ecosystem with world-class solutions and services, CSC, AMD and UPM strongly believe in the capabilities of the Kajaani site and the opportunities it can provide to drive business growth.

“We have a proven data center ecosystem at Kajaani. There’s plenty of room for data center businesses to grow in our park facilities, where we offer fast delivery to market – thanks to the decommissioned site – and a smooth permitting and planning process. “, says Havanka.

As interest and visibility grows in the Kajaani region, CSC is dedicated to growing businesses related to its program, finding new operators who can benefit from hosting part of their footprint in the region. from Kainuu. Finland.

These advantages and opportunities of operating in the Kainuu region include:

  • Cost efficiency – cheap electricity and reimbursement for the use of waste heat.
  • World Class References – such as the LUMI EuroHPC project.
  • One of the most eco-efficient data centers in the world – low carbon footprints and excess amounts of renewable energy are increasingly in demand.
  • Data – extremely efficient connection.
  • Provision of HPC environments – CSC has solid knowledge and a track record of reliability and excellence in this field.
  • Unique ecosystem – offering professional partner expertise, dedicated training and RDI.

“We want everyone to understand the opportunities and benefits that can be derived from hosting their data centers in our Kajaani base. Our data center ecosystem with the LUMI EuroHPC supercomputer as a public benchmark significantly strengthens the role of Finland – and Kainuu in particular – in the European and global high-performance computing ecosystem,” says Partanen.

He concludes: “At the same time, it will strengthen the national and international status of Kainuu’s ICT and Data Center services. Kainuu now has the opportunity to take advantage of the new insights and build its data center ecosystem to a new and improved level. Now is the perfect time to attract new operators, to establish their presence as the best data center location in the world.
