Created by Philippe Notton, SiPearl is designing the high-performance, low-power microprocessor for European exascale supercomputers. This new generation of microprocessors will enable Europe to set out its technological sovereignty in strategic HPC markets such as artificial intelligence, medical research or climate modelling. The company is working in close collaboration with its 27 partners from the European Processor Initiative (EPI) consortium - leading names from the scientific community, supercomputing centres and industry - which are its stakeholders, future clients and end-users. SiPearl employs more than 100 people in France (Maisons-Laffitte, Grenoble, Massy, Sophia Antipolis), Germany (Duisburg) and Spain (Barcelona).
