Nov 3 (Reuters) – Supercomputer maker Bull and Schwarz Digits, the technology arm of Lidl-owner Schwarz Group, ​signed a preliminary agreement on Tuesday ‌to jointly develop AI computing services that would operate entirely under European jurisdiction, a link-up of two companies with big AI bets.

Under ‌the ​agreement, Schwarz Digits will ⁠offer the service through ⁠its STACKIT business, which rents out computing power and data storage over the internet. Bull, the state-owned French maker of ​Europe’s fastest supercomputers, will handle manufacturing.

The two companies plan to design servers filling ⁠the data centres together, ⁠and could eventually offer business ​software from Germany’s SAP through the partnership, they ​said. Financial terms of the deal ‌were not disclosed.

Companies and public bodies using STACKIT will also be able to use Bull’s software for building and running ⁠AI applications directly on the service.

Bull in October doubled production capacity in the only plant in ⁠Europe dedicated ‌to building supercomputers, while Schwarz ⁠is leading a C$7 billion ($5 ​billion) ‌funding round for Canadian AI ​lab Cohere, which ⁠is expanding in Europe through the acquisitions of German AI startup Aleph Alpha and Czech-based cybersecurity firm Aisle.
