GeoOrchestra: Orchestrating Heterogeneous Geo-Distributed Training with Network-Aware Scheduling

GeoOrchestra is a system that decouples resource filtering from fine-grained strategy search by abstracting compute nodes via computation and memory profiles while modeling WAN links as a virtual hard pipe, which employs hetero-aware pruning to filter invalid resource sets and a resource-driven search that exploits resource disparities to maximize efficiency.
