How it was built
- Architecture
- Cray XK7
- Node
- One AMD Opteron CPU with one NVIDIA K20X Kepler GPU
- CPU–GPU interconnect
- PCI Gen2
- System interconnect
- Cray Gemini
- Cabinets
- 200
- Storage
- 32 PB at 1 TB/s, Lustre
- Titan was a rebuild of Jaguar rather than a new installation, with GPUs added to the existing cabinets.
- It made the case that accelerators, not more CPU sockets, were the route to the next order of magnitude.
