摘要
The last decade has seen high-performance computing (HPC) systems become denser and denser. Higher node and rack density has led to development of multi-level networks - at socket, node, ‘pod’, rack, and between nodes. As sockets become more complex with integrated or co-packaged heterogeneous architectures, this network complexity is going to increase. In this paper, we extend Structural Simulation Toolkit (SST) to model these multi-level networks designs. We demonstrate this newly introduced capability by modeling a combination of a few different network topologies at different levels of the system and simulating the performance of collectives and some popular HPC communication patterns.
