Abstract

Processor and system architectures that feature multiple memory controllers and/or ccNUMA characteristics are prone to show bottlenecks and erratic performance numbers on scientific codes. Although cache thrashing, aliasing conflicts, and ccNUMA locality and contention problems are well known for many types of systems, they take on peculiar forms on the new Sun UltraSPARC T2 and T2+ processors, which we use here as prototypical multi-core designs. We analyze performance patterns in low-level and application benchmarks and put some emphasis on a comparison of performance features between T2 and its successor. Furthermore we show ways to circumvent bottlenecks by careful data layout, placement and padding. © 2008 World Scientific Publishing Company.
