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".

Mateo Valero, director, BSC explained: "The acquisition of MareNostrum 5 will enable world-changing scientific breakthroughs such as the creation of digital twins to help solve global challenges like climate change and the advancement of precision medicine. In addition, [BSC] is committed to developing European hardware to be used in future generations of supercomputers and helping to achieve technological sovereignty for the EU's member states".
