Abstract

NUMA system depends heavily on software to deploy underlying hardware architecture to obtain the optimized performance. The routing table of NUMA nodes is a critical architecture information for optimization. The routing table is not always available and dynamic routing for broke links make it more complex. But there is no work addressing automatically generating the routing table without prior knowledge of inter-processor connection. The authors proposed an algorithm based on detecting the uncore disturbance by memory bandwidth or PMU events counting variance. The disturbance pattern vectors are obtained by running a dedicate benchmark. Then calculate the routing table begin with direct connected nodes and then to the longer distance routing path step by step. The experiment shows that the authors' algorithm work effective for some real NUMA systems and synthesized topologies and generate the correct routing tables.
