System Configuration
Bridges comprises over 850 computational nodes,
- Regular Shared Memory (RSM) nodes with 128GB RAM each
- Large Shared Memory (LSM) nodes with 3TB RAM each
- Extreme Shared Memory (ESM) nodes with 12TB RAM each
- Regular Shared Memory GPU (RSM-GPU), 48 nodes of two types:
- 16 nodes with 2 Tesla K80 GPUs and 128GB RAM each
- 32 nodes with 2 Tesla P100 GPUs and 128GB RAM each
- AI-GPU (AI-GPU) nodes - ten nodes of two types.
- Nine with 8 Volta V100 GPUs, 16GB GPU memory and 192GB RAM each ("Volta 16")
- An NVIDIA DGX-2, with 16 Volta V100 GPUs, 1.5TB RAM and an NVSwitch, which tightly couples the GPUs for capability and scaling ("Volta 32")
Bridges' computational nodes supply 1.3018 Pf/s and 274 TiB RAM. The Bridges system also includes more than 6PB of node-local storage and 10PB of shared storage in the Pylon file system.
In addtion to its computational nodes, Bridges contains a number of login, database, web server and data transfer nodes.
