Clusters of seemingly homogeneous compute nodes are increasingly heterogeneous within each node due to replication and distribution of node-level subsystems. This intra-node heterogeneity can adversely affect program execution performance by inflicting additional data-access costs when accessing non-local data. In this work-in-progress paper, we present extensions to the Cbench Scalable Testing Framework for analyzing main memory and PCIe data-access performance in modern NUMA architectures. The information provided by this tool will be of use for task scheduling, performance modeling, and evaluation of NUMA systems.
