InfraGraph (INFRAstructure GRAPH)
InfraGraph defines a model-driven, vendor-neutral API for capturing a system of systems suitable for use in co-designing AI/HPC solutions.
The model and API allows for defining physical infrastructure using a standardized graph like terminology.
In addition to the base graph definition, user provided annotations can extend the graph allowing for an unlimited number of different physical and/or logical characteristics/view.
Additional information such as background, schema and examples can be found in the online documentation.
Using InfraGraph CLI
InfraGraph ships with a CLI that lets you convert existing system descriptions into InfraGraph format and visualize infrastructure topologies.
Install using pip:
pip install infragraph
Or clone the repo and run make clean && make install, or download the .whl from releases and install it with pip install infragraph-<version>.whl.
Convert system formats to InfraGraph — translate output from tools like lstopo directly into an InfraGraph YAML/JSON definition:
# Convert lstopo XML output to an InfraGraph YAML file
infragraph translate lstopo -i lstopo_output.xml -o my_device.yaml --dump yaml
Visualize infrastructure topologies — generate an interactive, drillable HTML visualization from any InfraGraph definition:
# Generate a visualization with host and switch hints
infragraph visualize -i my_infrastructure.yaml -o ./viz --hosts "dgx_a100" --switches "leaf_switch,spine_switch"
# Then open ./viz/index.html in a browser
The visualizer produces a multi-level view: a top-level graph of instances and inter-device connectivity, with drill-down into each device's internal components (xPUs, NICs, CPUs, memory, PCIe topology, etc.).
Note: More converters and tools are work-in-progress. See the Ecosystem documentation for the full roadmap and we invite contributions from the community.
Chakra + InfraGraph Ecosystem
MLCommons Chakra captures AI workload details as Execution Traces — graphs of operators, tensors, dependencies, and timing. InfraGraph complements Chakra by representing the underlying infrastructure — hosts, NICs, xPUs/accelerators, interconnects, and topologies. Together, Chakra + InfraGraph let you pair workload traces with infrastructure blueprints to analyze current systems and co-design future ones, while safely sharing artifacts across teams and partners.
For more details, see the Ecosystem documentation.
Versioning Rules
Infragraph follows a structured versioning scheme to maintain consistency across releases and ensure clear dependency management. Each version reflects compatibility, schema evolution, and API stability expectations.
For versioning rules, refer this readme.
