Abstract :
The performance of a CC-NUMA system heavily depends on the amount of interconnection traffic. To reduce the number of remote accesses, an operating system needs to exploit the potential locality of the architecture. In this paper, we present a UNIX-based operating system enhanced for CC-NUMA. The kernel data structures and algorithms are revised for the architecture. We analyze the performance of the enhanced kernel by running SDET and AIM VII commercial benchmarks on a real CC-NUMA system
