Scalability & Performance
Resource Efficiency
Current Bottlenecks in AI Network Simulation
Training larger AI models is severely limited by network performance, yet analytically modeling these complex networks is nearly impossible. Existing software-based discrete event simulators (SDES) struggle significantly with scale, requiring over a week to simulate just one second of an 8,192-node AI cluster. This inefficiency makes designing and prototyping AI supercomputers prohibitively costly and time-consuming, hindering advancements in AI development.
FPGA-Based Network Simulation
Miniature introduces an FPGA-based network simulator that leverages hardware parallelism to model AI supercomputer networks. It abstracts networking elements into specialized hardware circuits for switches and endpoints, accurately emulating queues, internal states, and protocol stacks. Key design principles include a precise virtual timer for high fidelity, efficient header compression, and time-multiplexing circuits to share hardware resources among multiple simulated nodes.
Achieving Hyper-Scale Simulation
Miniature demonstrates exceptional scalability, simulating a 65,536-node AI cluster 4332 times faster than state-of-the-art software simulators on a single FPGA. It achieves this by efficiently modeling network nodes on FPGAs and using checkpointing and restore mechanisms with off-chip memory (HBM) for capacity expansion. Furthermore, the architecture supports scaling out to multiple FPGAs, enabling near-linear speedup as the number of FPGAs increases, making it viable for future AI clusters of 200,000 GPUs or more.
Optimized Resource Utilization
Miniature is designed for maximum efficiency, utilizing FPGA resources judiciously. A basic endpoint circuit requires just over 0.05% of FPGA logic cells and 0.3% of BRAM tiles. A 64-port switch uses only 2.77% of logic cells. This low resource footprint, combined with time-multiplexing and checkpointing, allows a single FPGA to accommodate a large number of simulated network nodes, ensuring that high-performance simulation is achieved with minimal hardware cost.
