This powerful supercomputer can now run on light instead of electric current

In addition to being one of the most powerful computers in the world and currently ranked 105 on the Top500 list, France’s Jean Zay supercomputer is now the first HPC to have a photonic coprocessor.

Unlike traditional processors that use electrical current, LightOn’s photonic coprocessor transmits and processes information using light. The company’s photonic coprocessor was added to the Jean Zay supercomputer under a pilot program with GENCI and IDRIS and represents not only a technological advance but also an industry first.
