Title:

Experiences with Intel dual-core processor systems: From small to large scales

Abstract:

In the past months Intel has moved its two processor lines used in HPC to dual-core technology. In this timeframe the RRZE has installed a 9 TFlop/s Infiniband Cluster based on Intel Xeon5160 (Woodcrest) and the LRZ Munich has upgraded its SGI Altix to 62 TFlop/s using Intel Montecito processors. The talk reports about experiences with both systems and discusses the performance characteristics of these machines using small benchmark kernels as well as large scale user applications such as lattice Boltzmann solver and a Multigrid solver based on hierarchical hybrid grids.
