Atos is building the new MareNostrum 5 supercomputer, with a new $160 million contract signed in part of the EuroHPC JU initiative, and once it's built it will be the fastest supercomputer in the European Union.

NVIDIA's new Grace Superchips will be powering the new Atos MareNostrum 5 supercomputer, which will be built in Spain and delivered to the Barcelona Supercomputing Centre (BSC) in 2023. Inside, the new MareNostrum 5 supercomputer will pack 314 petaflops of FP64 computing performance.
The compute and storage partitions will be operational within the year, reports HPC Wire, adding that the remainder of the MareNostrum 5 supercomputer to be "operational within the year". NVIDIA has also added that the system is "expected to enter deployment in 2023". BSC says that the new MareNostrum 5 supercomputer will be "fully powered with green energy, and will utilize heat reuse technology".
