How it was built
- Architecture
- HPE Cray EX
- Node
- One HPC- and AI-optimised 3rd Gen AMD EPYC CPU paired with AMD Instinct accelerators
- CPU–GPU interconnect
- AMD Infinity Fabric
- System interconnect
- HPE Slingshot, multiple NICs per node at 100 GB/s
- Cabinets
- 74
- Frontier was the first machine to record an exaflop on the TOP500's LINPACK benchmark.
- ORNL reached it with far fewer cabinets than its predecessors — 74, against 256 for Summit and 200 for Titan — by making each node substantially more powerful rather than adding floor space.
- The design goal was workloads that mix traditional modelling and simulation with AI.
