Abstract
In this paper we take a look at what the Intel Xeon Processor 7500 family, code namedNehalem-EX, brings to high performance computing. We compare two families of Intel Xeonbased systems (Intel Xeon 7500 and Intel Xeon 5600) and present a performance evolutionof 16 node clusters based on these CPUs. We compare CPU generations utilizing dual socketplatforms and a cluster across a number of HPC benchmarks and focused on differentperformance field and aspect. We will evaluate also technologies and features like Intels HyperThreading Technology (HT) and Intel Turbo Boost Technology (Turbo Mode) and theperformance implication of these technologies for HPC.
