description This thesis presents a comprehensive evaluation of the New Generation General Pur- pose Partition of the MareNostrum 5 supercomputer, deployed at the Barcelona Su- percomputing Center, and built on the NVIDIA Grace CPU architecture. The anal- ysis is conducted at three levels: micro-benchmarks targeting specific system compo- nents, High Performance Computing benchmarks for system-to-system comparisons, and a performance study using a scientific application that simulates a real-world workload. Additionally, this work compares the new cluster to the two existing oper- ational partitions of MareNostrum 5, the General Purpose and Accelerated Partition, both of which are based on Intel's Sapphire Rapids micro-architecture. This com- parison aims to assess the maturity and competitiveness of the NVIDIA Grace-based system relative to established technologies.
